Configuring the Simple Network Management Protocol (SNMP)

RFC 1213 (MIB-II) MIB

The system group

sysDescr: A textual description of the entity. This value should include the full name and version identification of the system's hardware type, software operating-system, and networking software. It is mandatory that this only contain printable ASCII characters.
sysObjectID: The vendor's authoritative identification of the network management subsystem contained in the entity. This value is allocated within the SMI enterprises subtree (1.3.6.1.4.1) and provides an easy and unambiguous means for determining `what kind of box' is being managed. For example, if a vendor was assigned the subtree 1.3.6.1.4.1.4242, it could assign the identifier 1.3.6.1.4.1.4242.1.1 to its router.
sysUpTime: The time (in hundredths of a second) since the network management portion of the system was last re-initialized.
sysContact: The textual identification of the contact person for this managed node, together with information on how to contact this person.
sysName: An administratively-assigned name for this managed node. By convention, this is the node's fully-qualified domain name.
sysLocation: The physical location of this node (for example, `telephone closet, 3rd floor').
sysServices: A value which indicates the set of services that this entity primarily offers.
The value is a sum. This sum initially takes the value zero, Then, for each layer, L, in the range 1 through 7, that this node performs transactions for, 2 raised to (L - 1) is added to the sum. For example, a node which performs primarily routing functions would have a value of 4 (2^(3-1)). In contrast, a node which is a host offering application services would have a value of 72 (2^(4-1) + 2^(7-1)). Note that in the context of the Internet suite of protocols, values should be calculated accordingly: Layer 1 is the physical layer (for example, repeaters). Layer 2 is the datalink/subnetwork layer (for example, bridges). Layer 3 is the internet layer (for example, IP gateways). Layer 4 is the end-to-end layer (for example, IP hosts). Layer 7 is the applications layer (for example, mail relays). For systems including OSI protocols, layers 5 and 6 may also be counted.

The interfaces (if) group

ifNumber: The number of network interfaces (regardless of their current state) present on this system.
ifTable: A list of interface entries. The number of entries is given by the value of ifNumber.
ifEntry: An interface entry containing objects at the subnetwork layer and below for a particular interface.
ifIndex: A unique value for each interface. Its value ranges between 1 and the value of ifNumber. The value for each interface must remain constant at least from one re-initialization of the entity's network management system to the next re- initialization.
ifDescr: A textual string containing information about the interface. This string should include the name of the manufacturer, the product name and the version of the hardware interface.
ifType: The type of interface, distinguished according to the physical/link protocol(s) immediately `below' the network layer in the protocol stack.
ifMtu: The size of the largest datagram which can be sent/received on the interface, specified in octets. For interfaces that are used for transmitting network datagrams, this is the size of the largest network datagram that can be sent on the interface.
ifSpeed: An estimate of the interface's current bandwidth in bits per second. For interfaces which do not vary in bandwidth or for those where no accurate estimation can be made, this object should contain the nominal bandwidth.
ifPhysAddress: The interface's address at the protocol layer immediately `below' the network layer in the protocol stack. For interfaces which do not have such an address (for example, a serial line), this object should contain an octet string of zero length.
ifAdminStatus: The desired state of the interface. States are running(1), down(2), and testing(3). The testing state indicates that no operational packets can be passed.
ifOperStatus: The current operational state of the interface. States are running(1), down(2), and testing(3). The testing state indicates that no operational packets can be passed.
ifLastChange: The value of sysUpTime at the time the interface entered its current operational state. If the current state was entered prior to the last re- initialization of the local network management subsystem, then this object contains a zero value.
ifInOctets: The total number of octets received on the interface, including framing characters.
ifInUcastPkts: The number of subnetwork-unicast packets delivered to a higher-layer protocol.
ifInNUcastPkts: The number of non-unicast (that is, subnetwork- broadcast or subnetwork-multicast) packets delivered to a higher-layer protocol.
ifInDiscards: The number of inbound packets which were chosen to be discarded even though no errors had been detected to prevent their being deliverable to a higher-layer protocol. One possible reason for discarding such a packet could be to free up buffer space.
ifInErrors: The number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol.
ifInUnknownProtos: The number of packets received via the interface which were discarded because of an unknown or unsupported protocol.
ifOutOctets: The total number of octets transmitted out of the interface, including framing characters.
ifOutUcastPkts: The total number of packets that higher-level protocols requested be transmitted to a subnetwork-unicast address, including those that were discarded or not sent.
ifOutNUcastPkts: The total number of packets that higher-level protocols requested be transmitted to a non- unicast (that is, a subnetwork-broadcast or subnetwork-multicast) address, including those that were discarded or not sent.
ifOutDiscards: The number of outbound packets which were chosen to be discarded even though no errors had been detected to prevent their being transmitted. One possible reason for discarding such a packet could be to free up buffer space.
ifOutErrors: The number of outbound packets that could not be transmitted because of errors.
ifOutQLen: The length of the output packet queue (in packets).
ifSpecific: A reference to MIB definitions specific to the particular media being used to realize the interface. For example, if the interface is realized by an ethernet, then the value of this object refers to a document defining objects specific to ethernet. If this information is not present, its value should be set to the OBJECT IDENTIFIER { 0 0 }, which is a syntactically valid object identifier, and any conformant implementation of ASN.1 and BER must be able to generate and recognize this value.

The address translation (at) group

atTable: The Address Translation tables contain the NetworkAddress to `physical' address equivalences. Some interfaces do not use translation tables for determining address equivalences (for example, DDN-X.25 has an algorithmic method); if all interfaces are of this type, then the Address Translation table is empty, that is, has zero entries.
atEntry: Each entry contains one NetworkAddress to `physical' address equivalence.
atIfIndex: The interface on which this entry's equivalence is effective. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex.
atPhysAddress: The media-dependent `physical' address.
Setting this object to a null string (one of zero length) has the effect of invaliding the corresponding entry in the atTable object. That is, it effectively disassociates the interface identified with said entry from the mapping identified with said entry. It is an implementation-specific matter as to whether the agent removes an invalidated entry from the table. Accordingly, management stations must be prepared to receive tabular information from agents that corresponds to entries not currently in use. Proper interpretation of such entries requires examination of the relevant atPhysAddress object.
atNetAddress: The NetworkAddress (for example, the IP address) corresponding to the media-dependent `physical' address.

The internet protocol (ip) group

ipForwarding: The indication of whether this entity is acting as an IP gateway in respect to the forwarding of datagrams received by, but not addressed to, this entity. IP gateways forward datagrams. IP hosts do not (except those source-routed via the host). Note that for some managed nodes, this object may take on only a subset of the values possible. Accordingly, it is appropriate for an agent to return a `badValue' response if a management station attempts to change this object to an inappropriate value.
ipDefaultTTL: The default value inserted into the Time-To-Live field of the IP header of datagrams originated at this entity, whenever a TTL value is not supplied by the transport layer protocol.
ipInReceives: The total number of input datagrams received from interfaces, including those received in error.
ipInHdrErrors: The number of input datagrams discarded due to errors in their IP headers, including bad checksums, version number mismatch, other format errors, time-to-live exceeded, errors discovered in processing their IP options, etc.
ipInAddrErrors: The number of input datagrams discarded because the IP address in their IP header's destination field was not a valid address to be received at this entity. This count includes invalid addresses (for example, 0.0.0.0) and addresses of unsupported Classes (for example, Class E). For entities which are not IP Gateways and therefore do not forward datagrams, this counter includes datagrams discarded because the destination address was not a local address.
ipForwDatagrams: The number of input datagrams for which this entity was not their final IP destination, as a result of which an attempt was made to find a route to forward them to that final destination. In entities which do not act as IP Gateways, this counter will include only those packets which were Source-Routed via this entity, and the Source- Route option processing was successful.
ipInUnknownProtos: The number of locally-addressed datagrams received successfully but discarded because of an unknown or unsupported protocol.
ipInDiscards: The number of input IP datagrams for which no problems were encountered to prevent their continued processing, but which were discarded (for example, for lack of buffer space). Note that this counter does not include any datagrams discarded while awaiting re-assembly.
ipInDelivers: The total number of input datagrams successfully delivered to IP user-protocols (including ICMP).
ipOutRequests: The total number of IP datagrams which local IP user-protocols (including ICMP) supplied to IP in requests for transmission. Note that this counter does not include any datagrams counted in
ipOutDiscards: The number of output IP datagrams for which no problem was encountered to prevent their transmission to their destination, but which were discarded (for example, for lack of buffer space). Note that this counter would include datagrams counted in ipForwDatagrams if any such packets met this (discretionary) discard criterion.
ipOutNoRoutes: The number of IP datagrams discarded because no route could be found to transmit them to their destination. Note that this counter includes any packets counted in ipForwDatagrams which meet this `no-route' criterion. Note that this includes any datagrams which a host cannot route because all of its default gateways are down.
ipReasmTimeout: The maximum number of seconds which received fragments are held while they are awaiting reassembly at this entity.
ipReasmReqds: The number of IP fragments received which needed to be reassembled at this entity.
ipReasmOKs: The number of IP datagrams successfully re- assembled.
ipReasmFails: The number of failures detected by the IP re- assembly algorithm (for whatever reason: timed out, errors, etc). Note that this is not necessarily a count of discarded IP fragments since some algorithms (notably the algorithm in RFC 815) can lose track of the number of fragments by combining them as they are received.
ipFragOKs: The number of IP datagrams that have been successfully fragmented at this entity.
ipFragFails: The number of IP datagrams that have been discarded because they needed to be fragmented at this entity but could not be, for example, because their Don't Fragment flag was set.
ipFragCreates: The number of IP datagram fragments that have been generated as a result of fragmentation at this entity.
ipAddrTable: The table of addressing information relevant to this entity's IP addresses.
ipAddrEntry: The addressing information for one of this entity's IP addresses.
ipAdEntAddr: The IP address to which this entry's addressing information pertains.
ipAdEntIfIndex: The index value which uniquely identifies the interface to which this entry is applicable. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex.
ipAdEntNetMask: The subnet mask associated with the IP address of this entry. The value of the mask is an IP address with all the network bits set to 1 and all the hosts bits set to 0.
ipAdEntBcastAddr: The value of the least-significant bit in the IP broadcast address used for sending datagrams on the (logical) interface associated with the IP address of this entry. For example, when the Internet standard all-ones broadcast address is used, the value will be 1. This value applies to both the subnet and network broadcasts addresses used by the entity on this (logical) interface.
ipAdEntReasmMaxSize: The size of the largest IP datagram which this entity can re-assemble from incoming IP fragmented datagrams received on this interface.
ipRouteTable: This entity's IP Routing table.
ipRouteEntry: A route to a particular destination.
ipRouteDest: The destination IP address of this route. An entry with a value of 0.0.0.0 is considered a default route. Multiple routes to a single destination can appear in the table, but access to such multiple entries is dependent on the table- access mechanisms defined by the network management protocol in use.
ipRouteIfIndex: The index value which uniquely identifies the local interface through which the next hop of this route should be reached. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex.
ipRouteMetric1: The primary routing metric for this route. The semantics of this metric are determined by the routing-protocol specified in the route's ipRouteProto value. If this metric is not used, its value should be set to -1.
ipRouteMetric2: An alternate routing metric for this route. The semantics of this metric are determined by the routing-protocol specified in the route's ipRouteProto value. If this metric is not used, its value should be set to -1.
ipRouteMetric3: An alternate routing metric for this route. The semantics of this metric are determined by the routing-protocol specified in the route's ipRouteProto value. If this metric is not used, its value should be set to -1.
ipRouteMetric4: An alternate routing metric for this route. The semantics of this metric are determined by the routing-protocol specified in the route's ipRouteProto value. If this metric is not used, its value should be set to -1.
ipRouteNextHop: The IP address of the next hop of this route. (In the case of a route bound to an interface which is realized via a broadcast media, the value of this field is the agent's IP address on that interface.)
ipRouteType: The type of route. Note that the values direct(3) and indirect(4) refer to the notion of direct and indirect routing in the IP architecture. Setting this object to the value invalid(2) has the effect of invalidating the corresponding entry in the ipRouteTable object. That is, it effectively disassociates the destination identified with said entry from the route identified with said entry. It is an implementation-specific matter as to whether the agent removes an invalidated entry from the table. Accordingly, management stations must be prepared to receive tabular information from agents that corresponds to entries not currently in use. Proper interpretation of such entries requires examination of the relevant ipRouteType object.
ipRouteProto: The routing mechanism via which this route was learned. Inclusion of values for gateway routing protocols is not intended to imply that hosts should support those protocols.
ipRouteAge: The number of seconds since this route was last updated or otherwise determined to be correct. Note that no semantics of `too old' can be implied except through knowledge of the routing protocol by which the route was learned.
ipRouteMask: Indicate the mask to be logical-ANDed with the destination address before being compared to the value in the ipRouteDest field. For those systems that do not support arbitrary subnet masks, an agent constructs the value of the ipRouteMask by determining whether the value of the correspondent ipRouteDest field belong to a class-A, B, or C network, and then using one of the following masks: 255.0.0.0 for a class-A network; 255.255.0.0 for a class-B network; 255.255.255.0 for a class-C network. If the value of the ipRouteDest is 0.0.0.0 (a default route), then the mask value is also 0.0.0.0. It should be noted that all IP routing subsystems implicitly use this mechanism.
ipRouteMetric5: An alternate routing metric for this route. The semantics of this metric are determined by the routing-protocol specified in the route's ipRouteProto value. If this metric is not used, its value should be set to -1.
ipRouteInfo: A reference to MIB definitions specific to the particular routing protocol which is responsible for this route, as determined by the value specified in the route's ipRouteProto value. If this information is not present, its value should be set to the OBJECT IDENTIFIER { 0 0 }, which is a syntatically valid object identifier, and any conformant implementation of ASN.1 and BER must be able to generate and recognize this value.
ipNetToMediaTable: The IP Address Translation table used for mapping from IP addresses to physical addresses.
ipNetToMediaEntry: Each entry contains one IpAddress to `physical' address equivalence.
ipNetToMediaIfIndex: The interface on which this entry's equivalence is effective. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex.
ipNetToMediaPhysAddress: The media-dependent `physical' address.
ipNetToMediaNetAddress: The IpAddress corresponding to the media- dependent `physical' address.
ipNetToMediaType: The type of mapping. Setting this object to the value invalid(2) has the effect of invalidating the corresponding entry in the ipNetToMediaTable. That is, it effectively disassociates the interface identified with said entry from the mapping identified with said entry. It is an implementation-specific matter as to whether the agent removes an invalidated entry from the table. Accordingly, management stations must be prepared to receive tabular information from agents that corresponds to entries not currently in use. Proper interpretation of such entries requires examination of the relevant ipNetToMediaType object.
ipRoutingDiscards: The number of routing entries which were chosen to be discarded even though they are valid. One possible reason for discarding such an entry could be to free-up buffer space for other routing entries.

The icmp group

icmpInMsgs: The total number of ICMP messages which the entity received. Note that this counter includes all those counted by icmpInErrors.

icmpInAddrMasks: The number of ICMP Address Mask Request messages received.
icmpInAddrMaskReps: The number of ICMP Address Mask Reply messages received.
icmpOutMsgs: The total number of ICMP messages which this entity attempted to send. Note that this counter includes all those counted by icmpOutErrors.
icmpOutErrors: The number of ICMP messages which this entity did not send due to problems discovered within ICMP such as a lack of buffers. This value should not include errors discovered outside the ICMP layer such as the inability of IP to route the resultant datagram. In some implementations there may be no types of error which contribute to this counter's value.
icmpOutDestUnreachs: The number of ICMP Destination Unreachable messages sent.
icmpOutTimeExcds: The number of ICMP Time Exceeded messages sent.
icmpOutParmProbs: The number of ICMP Parameter Problem messages sent.
icmpOutSrcQuenchs: The number of ICMP Source Quench messages sent.
icmpOutRedirects: The number of ICMP Redirect messages sent. For a host, this object will always be zero, since hosts do not send redirects.
icmpOutEchos: The number of ICMP Echo (request) messages sent.
icmpOutEchoReps: The number of ICMP Echo Reply messages sent.
icmpOutTimestamps: The number of ICMP Timestamp (request) messages sent.
icmpOutTimestampReps: The number of ICMP Timestamp Reply messages sent.

icmpOutAddrMaskReps: The number of ICMP Address Mask Reply messages sent.

The tcp group

tcpRtoAlgorithm: The algorithm used to determine the timeout value used for retransmitting unacknowledged octets.
tcpRtoMin: The minimum value permitted by a TCP implementation for the retransmission timeout, measured in milliseconds. More refined semantics for objects of this type depend upon the algorithm used to determine the retransmission timeout. In particular, when the timeout algorithm is ``rsre '' (3), an object of this type has the semantics of the LBOUND quantity described in RFC 793.
tcpRtoMax: The maximum value permitted by a TCP implementation for the retransmission timeout, measured in milliseconds. More refined semantics for objects of this type depend upon the algorithm used to determine the retransmission timeout. In particular, when the timeout algorithm is ``rsre'' (3), an object of this type has the semantics of the UBOUND quantity described in RFC 793.
tcpMaxConn: The limit on the total number of TCP connections the entity can support. In entities where the maximum number of connections is dynamic, this object should contain the value -1.
tcpActiveOpens: The number of times TCP connections have made a direct transition to the SYN-SENT state from the CLOSED state.
tcpPassiveOpens: The number of times TCP connections have made a direct transition to the SYN-RCVD state from the LISTEN state.
tcpAttemptFails: The number of times TCP connections have made a direct transition to the CLOSED state from either the SYN-SENT state or the SYN-RCVD state, plus the number of times TCP connections have made a direct transition to the LISTEN state from the SYN-RCVD state.

tcpConnTable: A table containing TCP connection-specific information.
tcpConnEntry: Information about a particular current TCP connection. An object of this type is transient, in that it ceases to exist when (or soon after) the connection makes the transition to the CLOSED state.
tcpConnState: The state of this TCP connection. The only value which may be set by a management station is deleteTCB(12). Accordingly, it is appropriate for an agent to return a `badValue' response if a management station attempts to set this object to any other value. If a management station sets this object to the value deleteTCB(12), then this has the effect of deleting the TCB (as defined in RFC 793) of the corresponding connection on the managed node, resulting in immediate termination of the connection. As an implementation-specific option, a RST segment may be sent from the managed node to the other TCP endpoint (note however that RST segments are not sent reliably).
tcpConnLocalAddress: The local IP address for this TCP connection. In the case of a connection in the listen state which is willing to accept connections for any IP interface associated with the node, the value 0.0.0.0 is used.
tcpConnLocalPort: The local port number for this TCP connection.
tcpConnRemAddress: The remote IP address for this TCP connection.
tcpConnRemPort: The remote port number for this TCP connection.
tcpInErrs: The total number of segments received in error (for example, bad TCP checksums).

egpOutErrors: The number of locally generated EGP messages not sent due to resource limitations within an EGP entity.
egpNeighTable: The EGP neighbor table.
egpNeighEntry: Information about this entity's relationship with a particular EGP neighbor.

egpNeighOutErrMsgs: The number of EGP-defined error messages sent to this EGP peer.
egpNeighStateUps: The number of EGP state transitions to the UP state with this EGP peer.
egpNeighStateDowns: The number of EGP state transitions from the UP state to any other state with this EGP peer.
egpNeighIntervalHello: The interval between EGP Hello command retransmissions (in hundredths of a second). This represents the t1 timer as defined in RFC 904.
egpNeighIntervalPoll: The interval between EGP poll command retransmissions (in hundredths of a second). This represents the t3 timer as defined in RFC 904.
egpNeighMode: The polling mode of this EGP entity, either passive or active.
egpNeighEventTrigger: A control variable used to trigger operator- initiated Start and Stop events. When read, this variable always returns the most recent value that egpNeighEventTrigger was set to. If it has not been set since the last initialization of the network management subsystem on the node, it returns a value of `stop'. When set, this variable causes a Start or Stop event on the specified neighbor, as specified on pages 8-10 of RFC 904. Briefly, a Start event causes an Idle peer to begin neighbor acquisition and a non-Idle peer to reinitiate neighbor acquisition. A stop event causes a non-Idle peer to return to the Idle state until a Start event occurs, either via egpNeighEventTrigger or otherwise.
egpAs: The autonomous system number of this EGP entity.

snmpInReadOnlys: The total number valid SNMP PDUs which were delivered to the SNMP protocol entity and for which the value of the error-status field is `readOnly'. It should be noted that it is a protocol error to generate an SNMP PDU which contains the value `readOnly' in the error-status field, as such this object is provided as a means of detecting incorrect implementations of the SNMP.
snmpInGenErrs: The total number of SNMP PDUs which were delivered to the SNMP protocol entity and for which the value of the error-status field is `genErr'.
snmpInTotalReqVars: The total number of MIB objects which have been retrieved successfully by the SNMP protocol entity as the result of receiving valid SNMP Get-Request and Get-Next PDUs.

snmpOutGenErrs: The total number of SNMP PDUs which were generated by the SNMP protocol entity and for which the value of the error-status field is `genErr'.
snmpOutGetRequests: The total number of SNMP Get-Request PDUs which have been generated by the SNMP protocol entity.
snmpOutGetNexts: The total number of SNMP Get-Next PDUs which have been generated by the SNMP protocol entity.
snmpOutSetRequests: The total number of SNMP Set-Request PDUs which have been generated by the SNMP protocol entity.
snmpOutGetResponses: The total number of SNMP Get-Response PDUs which have been generated by the SNMP protocol entity.
snmpOutTraps: The total number of SNMP Trap PDUs which have been generated by the SNMP protocol entity.
snmpEnableAuthenTraps: Indicates whether the SNMP agent process is permitted to generate authentication-failure traps. The value of this object overrides any configuration information; as such, it provides a means whereby all authentication-failure traps may be disabled. Note that it is strongly recommended that this object be stored in non-volatile memory so that it remains constant between re-initializations of the network management system.
