Commands Supporting High Availability for Multiservices PICs
The following operational commands support Multiservices PIC redundancy:
- clear interfaces statistics—Clear interface statistics. When the show interfaces statistics command is next issued, the output shows the packets received since the last time the clear interfaces statistics command was issued. However, after a graceful Routing Engine switchover (GRES), output from the show interfaces statistics command includes cumulative statistics.
- request interface (revert | switchover)—Manually change over to the other PIC. Use revert to revert to the primary interface; use switchover to change, or switch over, to the secondary interface. After the switchover, it is recommended you place the old active PIC offline temporarily so it comes up fresh as a new backup.
- show interfaces redundancy—Display general information about the rms and ms- interfaces redundancy. You can use this command to determine which PIC is currently active.
- show interfaces statistics—Display interface statistics, such as packets received, packets transmitted, and errors. This command has output in three different levels of detail.
For detail on these commands as used in support of the rms interface, including sample output, see their command summaries. For information on these commands in other contexts, see the Junos Interfaces Command Reference.
