Action

To disable the sending of link-layer keepalives on a Channelized OC12 or Channelized OC12 IQ interface, follow these steps:.

Note: For a list of interface types associated with the Channelized OC12 IQ interface, see JUNOS Network Interfaces Configuration Guide.

1. In configuration mode, go to the following hierarchy level:
   [edit]user@host# edit interfaces t3-fpc/pic/port:channel
2. Configure no-keepalives:
   [edit interfaces t3-fpc/pic/port:channel]user@host# set no-keepalives
3. Verify the configuration:
   user@host# show

   For example:

   [edit interfaces t3-0/1/1:8]user@host# show no-keepalives;
4. Commit the change:
   user@host# commit

   For example:

   [edit interfaces t3-0/1/1:8]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.
