The following table describes the IP tab fields.
Field Description DefaultTTL The default value inserted into the Time-To-Live (TTL) field of the IP header of datagrams originated at this entry, whenever a TTL value is not supplied by the transport layer protocol. The default value is 16. Reasm Timeout The maximum number of seconds that received fragments are held while they are awaiting reassembly at this entity. The default value is 5.
The IP Address tab displays the switch IP address information.
The following table describes the IP Address tab fields.
Field Description Addr The device IP address. NetMask The subnet mask address. BcastAddr The IP broadcast address used. ReasmMaxSize The size of the largest IP datagram that this entity can reassemble from incoming IP fragmented datagrams received on this interface.
The Address Resolution Protocol (ARP) tab displays the MAC addresses and the associated IP addresses for the switch.
The following table describes the ARP tab fields.
Field Description Interface The device unit number. MacAddress The unique hardware address of the device. IpAddress The Internet Protocol address of the device used to represent a point of attachment in a TCP/IP internetwork. Type The type of mapping.
Field Description Name The textual name of the interface. Index A unique value for each interface. Its value ranges from 0 to the value of ifNumber. The value for each interface must remain constant at least from one reinitialization of the entity's network management system to the next re initialization. Type The type of interface. Mtu The size of the largest packet which can be sent or received on the interface, specified in octets. Speed An estimate of the interface's current bandwidth in bits per second. PhysAddress The interface's address at its protocol sublayer. The interface's media-specific MIB must define the bit and byte ordering and format of the value. AdminStatus The desired state of the interface. The testing(3) state indicates that no operational packets can be passed. When a managed system is initialized, all interfaces start with ifAdminStatus in the down(2) state. As a result of either explicit management action or per configuration information retained by the managed system, ifAdminStatus is then changed to either the up(1) or testing(3) states (or remains in the down(2) state). OperStatus The current operational state of the interface. The testing(3) state indicates that no operational packets can be passed. If ifAdminStatus is down(2) then ifOperStatus should be down(2). If ifAdminStatus is changed to up(1) then ifOperStatus should change to up(1) if the interface is ready to transmit and receive network traffic; it should change to dormant(5) if the interface is waiting for external actions (such as a serial line waiting for an incoming connection); it should remain in the down(2) state if and only if there is a fault that prevents it from going to the up(1) state. LastChange The value of sysUpTime at the time the interface entered its current operational state. If the current state was entered prior to the last reinitialization of the local network management subsystem, then this object contains a zero value. LinkTrap Indicates whether linkUp/linkDown traps should be generated for this interface.
The following table describes the Port Interface Tab fields.
Field Description ifInOctets The total number of octets received on the interface, including framing characters. ifOutOctets The total number of octets transmitted out of the interface, including framing characters. ifInUcastPkts The number of packets delivered by this sublayer to a higher sublayer that were not addressed to a multicast or broadcast address at this sublayer. ifOutUcastPkts The number of packets that higher-level protocols requested be transmitted that were not addressed to a multicast address at this sublayer. This total number includes those packets discarded or unsent. ifInNUcastPkts The number of packets delivered by this sublayer to a higher (sub)layer, which were addressed to a multicast or broadcast address at this sublayer. This object is depreciated in favor of ifInMulticastPkts and ifInBroadcastPkts. ifOutNUcastPkts The total number of packets that higher-level protocols requested be transmitted, and which were addressed to a multicast or broadcast address at this sublayer, including those that were discarded or not sent. This object is depreciated in favor of ifOutMulticastPkts and ifOutBroadcastPkts. InDiscards The number of inbound packets that were chosen to be discarded even though no errors were detected to prevent their being delivered to a higher-layer protocol. One possible reason for discarding such a packet is to free up buffer space. OutDiscards 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. InErrors For packet-oriented interfaces, the number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol. For character-oriented or fixed-length interfaces, the number of inbound transmission units that contained errors preventing them from being deliverable to a higher-layer protocol. OutErrors For packet-oriented interfaces, the number of outbound packets that could not be transmitted because of errors. For character-oriented or fixed-length interfaces, the number of outbound transmission units that could not be transmitted because of errors. InUnknownProtos For packet-oriented interfaces, the number of packets received through the interface that were discarded because of an unknown or unsupported protocol. For character-oriented or fixed-length interfaces that support protocol multiplexing, the number of transmission units received through the interface that were discarded because of an unknown or unsupported protocol. For any interface that does not support protocol multiplexing, this counter is always 0.
The SNMP tab displays the chassis SNMP statistics.

InReadOnlys The total number of SNMP PDUs delivered to SNMP for which the value of the error-status field is readOnly. It is a protocol error to generate an SNMP PDU containing the value “readOnly” in the error-status field. This object is provided to detect incorrect implementations of the SNMP. InGenErrs The total number of SNMP PDUs delivered to SNMP for which the value of the error-status field is genErr.
The following table describes the IP Tab fields.
Field Description InReceives The total number of input datagrams received from interfaces, including those received in error. InHdrErrors 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, or errors discovered in processing their IP options. InAddrErrors The number of input datagrams discarded because the IP address in the IP header destination field was not a valid address. This count includes invalid addresses (for example, 0.0.0.0) and addresses of unsupported Classes (for example, Class E). For addresses that are not IP gateways and therefore do not forward datagrams, this counter includes datagrams discarded because the destination address was not a local address. ForwDatagrams 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. For addresses that do not act as IP gateways, this counter includes only those packets that were source-routed by way of this address and had successful source-route option processing. InUnknownProtos The number of locally addressed datagrams received successfully but discarded because of an unknown or unsupported protocol. InDiscards The number of input IP datagrams for which no problems were encountered to prevent their continued processing but that were discarded (for example, for lack of buffer space). Note that this counter does not include any datagrams discarded while awaiting reassembly. InDelivers The total number of input datagrams successfully delivered to IP user protocols (including ICMP). OutRequests The total number of IP datagrams that 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. OutDiscards The number of output IP datagrams for which no problem was encountered to prevent their transmission to their destination, but that were discarded for example, for lack of buffer space. Note that this counter includes datagrams counted in ipForwDatagrams if any such packets met this discretionary discard criterion. OutNoRoutes 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 that meet this no-route criterion. Note that this includes any datagrams a host cannot route because all of its default gateways are down. FragOKs The number of IP datagrams that have been successfully fragmented at this entity. FragFails 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. FragCreates The number of IP datagram fragments that have been generated as a result of fragmentation at this entity. ReasmReqds The number of IP fragments received that needed to be reassembled at this entity. ReasmOKs The number of IP datagrams successfully reassembled. ReasmFails The number of failures detected by the IP reassembly algorithm (for whatever reason: timed out, errors, etc.). Note that this is not necessarily a count of discarded IP fragments because some algorithms (notably the algorithm in RFC 815) can lose track of the number of fragments by combining them as they are received.
