Monitoring the Policy Configuration of IP Interfaces

Purpose

Display information about an IP interface (including policy list statistics).

Action

To display information about IP policy lists:
host1#show ip interface serial 2/1:28/24.1
serial2/1:28/24.1 is up, line protocol is up
  Network Protocols: IP
  Internet address is 172.24.1.101/255.255.255.0
  Broadcast address is 255.255.255.255
  Operational MTU = 1600 Administrative MTU = 0
  Operational speed = 155520000  Administrative speed = 0
  Discontinuity Time = 14695
  Router advertisement = disabled
  Administrative debounce-time = disabled
  Operational debounce-time    = disabled
  Access routing = disabled

Meaning

Table 29: 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

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

Table 29 lists the show ip interfaces command output fields.
