Configure No-Keepalives

Action

To disable the sending of link-layer keepalives on a T1 physical interface, follow these steps:

  1. In configuration mode, go to the following hierarchy level:
    [edit]user@host# edit interfaces interface-name
  2. Configure no-keepalives:
    [edit interfaces interface-name]user@host# set no-keepalives

    For example:

    [edit interfaces t1-1/3/0]user@host# set no-keepalives
  3. Verify the configuration:
    user@host# show

    For example:

    [edit interfaces t1-1/3/0]user@host# show no-keepalives;
  4. Commit the change:
    user@host# commit

    For example:

    [edit interfaces t1-1/3/0]user@host# commit commit complete

Meaning

By setting no-keepalives, the link layer is forced to stay up. If the setting remains at keepalive, the router will recognize that the same link-layer keepalives are being looped back and will bring the link layer down.
