#### Meaning

Table 38 lists the show ip interfaces command output fields.

Table 38: show ip interfaces Output Fields

Field Name | Field Description
--- | ---
Network Protocols | Protocols configured on the interface
Internet address | IP address of the interface
Broadcast address | Broadcast address used by the interface
Operational MTU | Operational maximum transmission unit (MTU) for packets sent on this interface
Administrative MTU | Administrative maximum transmission unit for packets sent on this interface
Operational speed | Speed known to the IP layer in bits per second; equal to the administrative speed if configured, otherwise inherited from the lower layer
Administrative speed | Configured speed known to the IP layer in bits per second
Discontinuity Time | Time since the counters on the interface became invalid; for example, when the line module was reset
Router Advertisement | When enabled by the ip irdp command, the router advertises its presence via the ICMP Router Discovery Protocol (IRDP)
Administrative debounce-time | Administrative time delay that an interface must remain in a new state before the routing protocols react to the state change
Operational debounce-time | Time delay that an interface must remain in a new state before the routing protocols react to the state change
Access routing | When enabled, an access route is installed to the host on the other end of the interface
In Received Packets | Number of packets received on the interface; indicates whether packets are unicast or multicast
In Received Bytes | Number of bytes received on the interface; indicates whether bytes are unicast or multicast
In Policed Packets | Number of packets policed on the interface; discarded because they exceeded a traffic contract to their destination
In Policed Bytes | Number of bytes policed on the interface; discarded because they exceeded a traffic contract to their destination
In Error Packets | Number of packets determined to be in error at the interface
In Invalid Source Address Packets | Number of packets determined to have originated from an invalid source address
Out Forwarded Packets | Number of packets forwarded from the interface; indicates whether packets are unicast or multicast
Out Forwarded Bytes | Number of bytes forwarded from the interface; indicates whether bytes are unicast or multicast
Out Scheduler Drops Packets | Number of packets dropped by the out scheduler; indicates whether packets are committed, conformed, or exceeded
Out Scheduler Drops Bytes | Number of bytes dropped by the out scheduler; indicates whether bytes are committed, conformed, or exceeded
Policy | Indicates which policy is attached and whether it is on the input or output of the interface
classifier-group | Name of a CLACL attached to the interface and number of entry
exception http-redirect | Number of packets and bytes assigned to http-redirect
filter | Number of packets and bytes dropped because of the CLACL
color | Explicit color applied to packet flow for queuing; green, yellow, or red:
Packets logged | Number of packets colored
Bytes logged | Number of bytes colored
next hop | Address of the next-hop destination:
Packets transmitted | Number of packets sent to the next-hop address
Bytes transmitted | Number of bytes sent to the next-hop address
forward | Number of packets and bytes forwarded because of the CLACL
interface | Interface rule to forward all packets that match the current classifier control list
next-hop | Next-hop IP addresses are used as forwarding solutions, and the order of the rule within the classifier that the router uses to choose the solutions. The phrase in parenthesis describes whether the rule entry is reachable, active, and supported for the configured policy
rate-limit-profile | Name of the rate-limit profile
committed | Number of packets and bytes within the committed rate limit
conformed | Number of packets and bytes exceeding the committed rate limit but within the peak rate
exceeded | Number of packets and bytes exceeding the peak rate
action | Action performed on the packets matched by the rules in the rate-limit profile
