    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
      In Discarded Packets 0
      Out Forwarded Packets 1866, Bytes 84650
        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 1 lists the show ip address command output fields.

    Table 1: 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
