From the Table menu, select Interface Table.
The Interface Table lists the network interfaces (regardless of their current state) on which the selected device can send/receive IP datagrams. For each interface, the table shows descriptive data and current values of the counters (for example, inOctets, outOctets) used to assess the performance of the interface.
The columns in the Interface Table show the following information:
Index: A unique value that identifies the interface in the MIB’s ifTable (same as ifIndex).
Description: Can include the name of the manufacturer, the product name and the version of the hardware interface.
Interface Type: The type of interface, distinguished according to the physical/link/network protocol(s) immediately "below" IP in the protocol stack.
Address: The interface's address at the protocol layer immediately "below" IP in the protocol stack. For interfaces that do not have such an address (e.g., a serial line), this object should contain an octet string of zero length.
Admin Status: The desired state of the interface: Up – ready to pass packets; Down; or Testing – in some testing state.
Operator Status: The current state of the interface. Up – ready to pass packets; Down; or Testing – in some testing state.
MTU: The size of the largest IP datagram that can be sent/received on the interface, specified in octets.
Speed: An estimate of the interface's current bandwidth in bits per second. For interfaces that do not vary in bandwidth, or for those where no accurate estimation can be made, this object should contain the nominal bandwidth.
Last Change: 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.
InUCastPkts: The number of (subnet) unicast packets delivered to a higher-layer protocol.
InUNCastPkts: The number of non-unicast (i.e., subnet broadcast or subnet multicast) packets delivered to a higher-layer protocol.
InErrors: The number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol.
InDiscards: 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.
Unknown Protos: The number of packets received via the interface which were discarded because of an unknown or unsupported protocol.
OutUCastPkts: The total number of packets that higher-level protocols requested be transmitted to a subnet-unicast address, including those that were discarded or not sent.
OutNUCastPkts: The total number of packets that higher-level protocols requested be transmitted to a non-unicast (i.e., a subnet broadcast or subnet multicast) address, including those that were discarded or not sent.
OutErrors: The number of outbound packets that could not be transmitted because of errors.
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.
InOctets: The total number of octets received on the interface, including framing characters.
OutOctets: The total number of octets transmitted out of the interface, including framing characters.
See RFC 1213 and 1156 for complete descriptions of all objects.
