Monitoring Detailed or Summary Information for IP Interfaces

Purpose

Displays detailed or summary information about a particular IP interface. You can specify a VRF name to view information for only that VRF. You can use the brief keyword to display summary information about the interface. You can use the detail keyword to display detailed information about the interface.

Action

To display detailed or summary information about a particular IP interface:

host1#show ip address 10.6.136.73
fastEthernet0/0 is up, line protocol is up
  Network Protocols: IP
  Internet address is 10.6.136.73/255.255.128.0
  Broadcast address is 255.255.255.255
  Operational MTU = 0  Administrative MTU = 0
  Operational speed = 1  Administrative speed = 0
  Discontinuity Time = 5766
  Router advertisement = disabled
  Proxy Arp = disabled
  Administrative debounce-time = 10 mSecs
  Operational debounce-time    = disabled
  Access routing = disabled
  Multipath mode = hashed
  In Received Packets 2849, Bytes 759428
    Unicast Packets 2849, Bytes 759428
    Multicast Packets 0, Bytes 0
  In Policed Packets 0, Bytes 0
  In Error Packets 0
  In Invalid Source Address Packets 0

    Unicast Packets 1866, Bytes 84650
    Multicast Routed Packets 0, Bytes 0       
  Out Scheduler Drops Committed Packets 0, Bytes 0
  Out Scheduler Drops Conformed Packets 0, Bytes 0
  Out Scheduler Drops Exceeded  Packets 0, Bytes 0
  Out Policed Packets 0, Bytes 0
  Out Discarded Packets 0 

Meaning

Table 17 lists the show ip address command output fields.

Table 17: show ip address Output Fields

Field Name

Field Description

Network Protocols

Network protocols configured on this interface

Internet address

IP address and subnet mask of this interface

Broadcast address

Broadcast address of this interface

Operational MTU

MTU of this interface

Administrative MTU

Value of the MTU if it has been administratively overridden using the configuration

Operational speed

Speed of the interface

Administrative speed

Value of the speed if it has been administratively overridden using the configuration

Discontinuity Time

Value of the SysUpTime when the interface statistics last started being valid

Router advertisement

Status of router discovery advertisement: enabled, disabled

Proxy Arp

Status of the feature: enabled, disabled

Administrative debounce-time

Configured debounce behavior, enabled or disabled. If enabled, indicates time in milliseconds that the router waits before generating an up or down event in response to a state change in the interface. If the state changes back before the debounce timer expires, no state change is reported.

Operational debounce-time

Current debounce behavior, enabled or disabled. If enabled, indicates time in milliseconds that the router waits before generating an up or down event in response to a state change in the interface. If the state changes back before the debounce timer expires, no state change is reported.

Access routing

Access route addition: enabled, disabled

Multipath mode

Equal cost multipath mode method: hashed, round-robin

In Received Packets, Bytes

Total number of packets and bytes received on this interface:

  • Unicast Packets, Bytes—Unicast packets and bytes received on the IP interface; link-local received multicast packets (non-multicast-routed frames) are counted as unicast packets
  • Multicast Packets, Bytes—Multicast packets and bytes received on the IP interface which are then multicast-routed are counted as multicast packets

In Policed Packets, Bytes

Packets and bytes that were received and dropped for any of the following reasons: exceeding the token bucket limit, exceeding the rate limit, a drop action in a policy, discarded MAC validation packets, a destination address lookup failure, or when the destination address is an IP interface that has a route configured to the null 0 interface.

In Error Packets

Number of packets received with errors

In Invalid Source Address Packets

Packets received with invalid source address (for example, spoofed packets)

In Discarded Packets

Packets received that were discarded for reasons other than rate limits, errors, and invalid source address

Out Forwarded Packets, Bytes

Total number of packets and bytes that were sent from this interface:

  • Unicast Packets, Bytes—Unicast packets and bytes that were sent from this interface
  • Multicast Routed Packets, Bytes—Multicast packets and bytes that were sent from this interface

Out Scheduler Drops Committed Packets, Bytes

Outgoing packets and bytes dropped by the scheduler even though they had a committed traffic contract

Out Scheduler Drops Conformed Packets, Bytes

Outgoing packets and bytes dropped by the scheduler even though they conformed to the traffic contract

Out Scheduler Drops Exceeded Packets, Bytes

Outgoing packets and bytes that were dropped by the scheduler because they exceeded the contract

Out Policed Packets, Bytes

Outgoing packets and bytes dropped because of rate limiters

Out Discarded Packets

Outgoing packets that were discarded for reasons other than those dropped by the scheduler and those dropped because of rate limits
