What Is RFC-1213-MIB?
RFC-1213-MIB is the standard IETF MIB (RFC 1213), universally known as MIB-II, defining the foundational system, interface, address-translation, IP, ICMP, TCP, UDP, EGP, transmission, and SNMP object groups implemented by virtually every SNMP-managed device. Its objects include the system group (sysDescr, sysObjectID, sysUpTime, sysContact, sysName, sysLocation, sysServices), the interfaces group (ifNumber and the ifTable with ifIndex/ifDescr/ifType/ifMtu/ifSpeed/ifPhysAddress/ifAdminStatus/ifOperStatus/ifLastChange and traffic/error counters), and further groups for IP, ICMP, TCP, UDP, and EGP statistics. As the baseline management MIB it lets an administrator or NMS discover basic identity, uptime, and per-interface status/traffic on any compliant SNMP agent, forming the foundation nearly all monitoring tools build on. It is implemented by essentially every SNMP-capable network device, server, and appliance. This is the single most heavily searched foundational MIB in existence, since RFC 1213 (MIB-II) defines the baseline system/interface/IP/ICMP/TCP/UDP objects that virtually every SNMP-managed device on the internet implements.
IPNetwork Monitor allows you to monitor SNMP objects defined in RFC-1213-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
What Can Be Monitored
- baseline system identity, uptime, and interface status/traffic
Supported Devices
- Virtually every SNMP-capable network device, server, and appliance
Monitoring Examples
A monitoring tool queries sysUpTime and walks ifTable to establish basic reachability, uptime, and per-interface status for virtually any SNMP-managed device, using nothing but the universal RFC 1213 MIB-II.
OIDs
| OID symbolic | OID numeric | Type | Access | Description |
|---|---|---|---|---|
| mib_2 | 1.3.6.1.2.1 | |||
| system | 1.3.6.1.2.1.1 | |||
| STR sysDescr | 1.3.6.1.2.1.1.1 | DisplayString | read-only | 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. |
| OID sysObjectID | 1.3.6.1.2.1.1.2 | OBJECT IDENTIFIER | read-only | 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 vendor `Flintstones, Inc.' 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 `Fred Router'. |
| TIK sysUpTime | 1.3.6.1.2.1.1.3 | TimeTicks | read-only | The time (in hundredths of a second) since the network management portion of the system was last re-initialized. |
| STR sysContact | 1.3.6.1.2.1.1.4 | DisplayString | read-write | The textual identification of the contact person for this managed node, together with information on how to contact this person. |
| STR sysName | 1.3.6.1.2.1.1.5 | DisplayString | read-write | An administratively-assigned name for this managed node. By convention, this is the node's fully-qualified domain name. |
| STR sysLocation | 1.3.6.1.2.1.1.6 | DisplayString | read-write | The physical location of this node (e.g., `telephone closet, 3rd floor'). |
| INT sysServices | 1.3.6.1.2.1.1.7 | INTEGER | read-only | 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 functionality 1 physical (e.g., repeaters) 2 datalink/subnetwork (e.g., bridges) 3 internet (e.g., IP gateways) 4 end-to-end (e.g., IP hosts) 7 applications (e.g., mail relays) For systems including OSI protocols, layers 5 and 6 may also be counted. |
| interfaces | 1.3.6.1.2.1.2 | |||
| INT ifNumber | 1.3.6.1.2.1.2.1 | INTEGER | read-only | The number of network interfaces (regardless of their current state) present on this system. |
| ifTable | 1.3.6.1.2.1.2.2 | not-accessible | A list of interface entries. The number of entries is given by the value of ifNumber. | |
| ifEntry | 1.3.6.1.2.1.2.2.1 | not-accessible | An interface entry containing objects at the subnetwork layer and below for a particular interface. | |
| INT ifIndex | 1.3.6.1.2.1.2.2.1.1 | INTEGER | read-only | 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. |
| STR ifDescr | 1.3.6.1.2.1.2.2.1.2 | DisplayString | read-only | 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. |
| INT ifType | 1.3.6.1.2.1.2.2.1.3 | INTEGER | read-only | The type of interface, distinguished according to the physical/link protocol(s) immediately `below' the network layer in the protocol stack. Additional entries retrieved at iana.org. |
| INT ifMtu | 1.3.6.1.2.1.2.2.1.4 | INTEGER | read-only | 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. |
| GAU ifSpeed | 1.3.6.1.2.1.2.2.1.5 | Gauge | read-only | 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. |
| PHY ifPhysAddress | 1.3.6.1.2.1.2.2.1.6 | PhysAddress | read-only | 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 (e.g., a serial line), this object should contain an octet string of zero length. |
| INT ifAdminStatus | 1.3.6.1.2.1.2.2.1.7 | INTEGER | read-write | The desired state of the interface. The testing(3) state indicates that no operational packets can be passed. |
| INT ifOperStatus | 1.3.6.1.2.1.2.2.1.8 | INTEGER | read-only | The current operational state of the interface. The testing(3) state indicates that no operational packets can be passed. |
| TIK ifLastChange | 1.3.6.1.2.1.2.2.1.9 | TimeTicks | read-only | 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. |
| CTR ifInOctets | 1.3.6.1.2.1.2.2.1.10 | Counter | read-only | The total number of octets received on the interface, including framing characters. |
| CTR ifInUcastPkts | 1.3.6.1.2.1.2.2.1.11 | Counter | read-only | The number of subnetwork-unicast packets delivered to a higher-layer protocol. |
| CTR ifInNUcastPkts | 1.3.6.1.2.1.2.2.1.12 | Counter | read-only | The number of non-unicast (i.e., subnetwork- broadcast or subnetwork-multicast) packets delivered to a higher-layer protocol. |
| CTR ifInDiscards | 1.3.6.1.2.1.2.2.1.13 | Counter | read-only | 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. |
| CTR ifInErrors | 1.3.6.1.2.1.2.2.1.14 | Counter | read-only | The number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol. |
| CTR ifInUnknownProtos | 1.3.6.1.2.1.2.2.1.15 | Counter | read-only | The number of packets received via the interface which were discarded because of an unknown or unsupported protocol. |
| CTR ifOutOctets | 1.3.6.1.2.1.2.2.1.16 | Counter | read-only | The total number of octets transmitted out of the interface, including framing characters. |
| CTR ifOutUcastPkts | 1.3.6.1.2.1.2.2.1.17 | Counter | read-only | 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. |
| CTR ifOutNUcastPkts | 1.3.6.1.2.1.2.2.1.18 | Counter | read-only | The total number of packets that higher-level protocols requested be transmitted to a non- unicast (i.e., a subnetwork-broadcast or subnetwork-multicast) address, including those that were discarded or not sent. |
| CTR ifOutDiscards | 1.3.6.1.2.1.2.2.1.19 | Counter | read-only | 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. |
| CTR ifOutErrors | 1.3.6.1.2.1.2.2.1.20 | Counter | read-only | The number of outbound packets that could not be transmitted because of errors. |
| GAU ifOutQLen | 1.3.6.1.2.1.2.2.1.21 | Gauge | read-only | The length of the output packet queue (in packets). |
| OID ifSpecific | 1.3.6.1.2.1.2.2.1.22 | OBJECT IDENTIFIER | read-only | 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. |
| at | 1.3.6.1.2.1.3 | |||
| atTable | 1.3.6.1.2.1.3.1 | not-accessible | The Address Translation tables contain the NetworkAddress to `physical' address equivalences. Some interfaces do not use translation tables for determining address equivalences (e.g., DDN-X.25 has an algorithmic method); if all interfaces are of this type, then the Address Translation table is empty, i.e., has zero entries. | |
| atEntry | 1.3.6.1.2.1.3.1.1 | not-accessible | Each entry contains one NetworkAddress to `physical' address equivalence. | |
| INT atIfIndex | 1.3.6.1.2.1.3.1.1.1 | INTEGER | read-write | 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. |
| PHY atPhysAddress | 1.3.6.1.2.1.3.1.1.2 | PhysAddress | read-write | 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 dissasociates 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. |
| IP atNetAddress | 1.3.6.1.2.1.3.1.1.3 | IpAddress | read-write | The NetworkAddress (e.g., the IP address) corresponding to the media-dependent `physical' address. |
| ip | 1.3.6.1.2.1.4 | |||
| INT ipForwarding | 1.3.6.1.2.1.4.1 | INTEGER | read-write | 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. |
| INT ipDefaultTTL | 1.3.6.1.2.1.4.2 | INTEGER | read-write | 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. |
| CTR ipInReceives | 1.3.6.1.2.1.4.3 | Counter | read-only | The total number of input datagrams received from interfaces, including those received in error. |
| CTR ipInHdrErrors | 1.3.6.1.2.1.4.4 | Counter | read-only | 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. |
| CTR ipInAddrErrors | 1.3.6.1.2.1.4.5 | Counter | read-only | 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 (e.g., 0.0.0.0) and addresses of unsupported Classes (e.g., 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. |
| CTR ipForwDatagrams | 1.3.6.1.2.1.4.6 | Counter | read-only | 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. |
| CTR ipInUnknownProtos | 1.3.6.1.2.1.4.7 | Counter | read-only | The number of locally-addressed datagrams received successfully but discarded because of an unknown or unsupported protocol. |
| CTR ipInDiscards | 1.3.6.1.2.1.4.8 | Counter | read-only | The number of input IP datagrams for which no problems were encountered to prevent their continued processing, but which were discarded (e.g., for lack of buffer space). Note that this counter does not include any datagrams discarded while awaiting re-assembly. |
| CTR ipInDelivers | 1.3.6.1.2.1.4.9 | Counter | read-only | The total number of input datagrams successfully delivered to IP user-protocols (including ICMP). |
| CTR ipOutRequests | 1.3.6.1.2.1.4.10 | Counter | read-only | 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 ipForwDatagrams. |
| CTR ipOutDiscards | 1.3.6.1.2.1.4.11 | Counter | read-only | The number of output IP datagrams for which no problem was encountered to prevent their transmission to their destination, but which were discarded (e.g., for lack of buffer space). Note that this counter would include datagrams counted in ipForwDatagrams if any such packets met this (discretionary) discard criterion. |
| CTR ipOutNoRoutes | 1.3.6.1.2.1.4.12 | Counter | read-only | 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 datagarms which a host cannot route because all of its default gateways are down. |
| INT ipReasmTimeout | 1.3.6.1.2.1.4.13 | INTEGER | read-only | The maximum number of seconds which received fragments are held while they are awaiting reassembly at this entity. |
| CTR ipReasmReqds | 1.3.6.1.2.1.4.14 | Counter | read-only | The number of IP fragments received which needed to be reassembled at this entity. |
| CTR ipReasmOKs | 1.3.6.1.2.1.4.15 | Counter | read-only | The number of IP datagrams successfully re- assembled. |
| CTR ipReasmFails | 1.3.6.1.2.1.4.16 | Counter | read-only | 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. |
| CTR ipFragOKs | 1.3.6.1.2.1.4.17 | Counter | read-only | The number of IP datagrams that have been successfully fragmented at this entity. |
| CTR ipFragFails | 1.3.6.1.2.1.4.18 | Counter | read-only | The number of IP datagrams that have been discarded because they needed to be fragmented at this entity but could not be, e.g., because their Don't Fragment flag was set. |
| CTR ipFragCreates | 1.3.6.1.2.1.4.19 | Counter | read-only | The number of IP datagram fragments that have been generated as a result of fragmentation at this entity. |
| ipAddrTable | 1.3.6.1.2.1.4.20 | not-accessible | The table of addressing information relevant to this entity's IP addresses. | |
| ipAddrEntry | 1.3.6.1.2.1.4.20.1 | not-accessible | The addressing information for one of this entity's IP addresses. | |
| IP ipAdEntAddr | 1.3.6.1.2.1.4.20.1.1 | IpAddress | read-only | The IP address to which this entry's addressing information pertains. |
| INT ipAdEntIfIndex | 1.3.6.1.2.1.4.20.1.2 | INTEGER | read-only | 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. |
| IP ipAdEntNetMask | 1.3.6.1.2.1.4.20.1.3 | IpAddress | read-only | 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. |
| INT ipAdEntBcastAddr | 1.3.6.1.2.1.4.20.1.4 | INTEGER | read-only | 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. |
| INT ipAdEntReasmMaxSize | 1.3.6.1.2.1.4.20.1.5 | INTEGER | read-only | The size of the largest IP datagram which this entity can re-assemble from incoming IP fragmented datagrams received on this interface. |
| ipRouteTable | 1.3.6.1.2.1.4.21 | not-accessible | This entity's IP Routing table. | |
| ipRouteEntry | 1.3.6.1.2.1.4.21.1 | not-accessible | A route to a particular destination. | |
| IP ipRouteDest | 1.3.6.1.2.1.4.21.1.1 | IpAddress | read-write | 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. |
| INT ipRouteIfIndex | 1.3.6.1.2.1.4.21.1.2 | INTEGER | read-write | 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. |
| INT ipRouteMetric1 | 1.3.6.1.2.1.4.21.1.3 | INTEGER | read-write | 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. |
| INT ipRouteMetric2 | 1.3.6.1.2.1.4.21.1.4 | INTEGER | read-write | 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. |
| INT ipRouteMetric3 | 1.3.6.1.2.1.4.21.1.5 | INTEGER | read-write | 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. |
| INT ipRouteMetric4 | 1.3.6.1.2.1.4.21.1.6 | INTEGER | read-write | 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. |
| IP ipRouteNextHop | 1.3.6.1.2.1.4.21.1.7 | IpAddress | read-write | 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.) |
| INT ipRouteType | 1.3.6.1.2.1.4.21.1.8 | INTEGER | read-write | 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 dissasociates 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. |
| INT ipRouteProto | 1.3.6.1.2.1.4.21.1.9 | INTEGER | read-only | 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. |
| INT ipRouteAge | 1.3.6.1.2.1.4.21.1.10 | INTEGER | read-write | 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. |
| IP ipRouteMask | 1.3.6.1.2.1.4.21.1.11 | IpAddress | read-write | 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: mask network 255.0.0.0 class-A 255.255.0.0 class-B 255.255.255.0 class-C 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. |
| INT ipRouteMetric5 | 1.3.6.1.2.1.4.21.1.12 | INTEGER | read-write | 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. |
| OID ipRouteInfo | 1.3.6.1.2.1.4.21.1.13 | OBJECT IDENTIFIER | read-only | 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 syntatcically valid object identifier, and any conformant implementation of ASN.1 and BER must be able to generate and recognize this value. |
| ipNetToMediaTable | 1.3.6.1.2.1.4.22 | not-accessible | The IP Address Translation table used for mapping from IP addresses to physical addresses. | |
| ipNetToMediaEntry | 1.3.6.1.2.1.4.22.1 | not-accessible | Each entry contains one IpAddress to `physical' address equivalence. | |
| INT ipNetToMediaIfIndex | 1.3.6.1.2.1.4.22.1.1 | INTEGER | read-write | 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. |
| PHY ipNetToMediaPhysAddress | 1.3.6.1.2.1.4.22.1.2 | PhysAddress | read-write | The media-dependent `physical' address. |
| IP ipNetToMediaNetAddress | 1.3.6.1.2.1.4.22.1.3 | IpAddress | read-write | The IpAddress corresponding to the media- dependent `physical' address. |
| INT ipNetToMediaType | 1.3.6.1.2.1.4.22.1.4 | INTEGER | read-write | 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 dissasociates 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. |
| CTR ipRoutingDiscards | 1.3.6.1.2.1.4.23 | Counter | read-only | 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. |
| icmp | 1.3.6.1.2.1.5 | |||
| CTR icmpInMsgs | 1.3.6.1.2.1.5.1 | Counter | read-only | The total number of ICMP messages which the entity received. Note that this counter includes all those counted by icmpInErrors. |
| CTR icmpInErrors | 1.3.6.1.2.1.5.2 | Counter | read-only | The number of ICMP messages which the entity received but determined as having ICMP-specific errors (bad ICMP checksums, bad length, etc.). |
| CTR icmpInDestUnreachs | 1.3.6.1.2.1.5.3 | Counter | read-only | The number of ICMP Destination Unreachable messages received. |
| CTR icmpInTimeExcds | 1.3.6.1.2.1.5.4 | Counter | read-only | The number of ICMP Time Exceeded messages received. |
| CTR icmpInParmProbs | 1.3.6.1.2.1.5.5 | Counter | read-only | The number of ICMP Parameter Problem messages received. |
| CTR icmpInSrcQuenchs | 1.3.6.1.2.1.5.6 | Counter | read-only | The number of ICMP Source Quench messages received. |
| CTR icmpInRedirects | 1.3.6.1.2.1.5.7 | Counter | read-only | The number of ICMP Redirect messages received. |
| CTR icmpInEchos | 1.3.6.1.2.1.5.8 | Counter | read-only | The number of ICMP Echo (request) messages received. |

| INT tcpRtoMin | 1.3.6.1.2.1.6.2 | INTEGER | read-only | 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. |
| INT tcpRtoMax | 1.3.6.1.2.1.6.3 | INTEGER | read-only | 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.

| INT tcpConnState | 1.3.6.1.2.1.6.13.1.1 | INTEGER | read-write | 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). |

| INT egpNeighEventTrigger | 1.3.6.1.2.1.8.5.1.15 | INTEGER | read-write | 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. |
