    Specifying an IP Debounce Time

    You can set a debounce time that requires an IP interface to be in a given state—for example, up or down—for the specified time before the state is reported. This feature prevents a link that briefly goes up or down from causing an unnecessary topology change, for example by causing an interface down condition. However, note that increasing the debounce time increases the latency of updating the routing table to reflect an up or down change, and the latency of routing protocols propagating the state change.

    To set the interval in milliseconds for which an interface must maintain a given state before the state change is reported:

    • Issue the ip debounce-time command in Global Configuration mode.
      host1(config)#ip debounce-time 5000

      Use the no version to remove the debounce time requirement.
