Description

On MX Series routers, enable timestamping of class-of-service (CoS) queues for a configured Flexible PIC Concentrator (FPC).

Options

enable

Display the last time a packet was enqueued as day, date, time, and year in the format day-of-the-week month day-date hh:mm:ss yyyy; for example, Mon Jul 7 07:36:46 2014. The Packet Forwarding Engine collects the timestamp for all inbound and outbound queue counters for all subscribers that are configured on the FPC and, when requested, also returns statistics corresponding to data traffic on the router.

If the timestamp is not enabled for the CoS queue, the Last-packet enqueued field is not displayed in statistics.

Note:

When you commit the change after enabling or disabling the timestamp feature for a particular FPC after that is already up, the FPC is automatically restarted and the change takes effect when it is back up.

The Routing Engine generates a system log message in the following situations:

  • When packet-timestamp is enabled and committed for an FPC slot, but the FPC inserted into that slot does not support timestamping.

  • When packet-timestamp is enabled and committed for an FPC slot, but an FPC that does not support timestamping is later inserted into that slot.
