show class-of-service fabric statistics

Syntax

Description

Display class-of-service (CoS) switch fabric queue statistics.

Note:

On the Switch Control Board (SCB) and the SCBE on MX Series routers, the ratio between high-priority queue and low-priority queue for traffic scheduled to enter the fabric is 85:15. However, on the SCBE2, this ratio is 97:3.

Note:

After an FPC restart, executing this command can return an Error = Operation timed out message for up to a minute even though the FPC is back online. No statistics are lost during this time, however.

Options

none	Same as summary.
destination `fpc-number`	(Optional) Display details for the specified destination Flexible PIC Concentrator (FPC). The FPC number is a value from 0 through 7 (depending on platform).
detail	(Optional) Display detailed statistics at the PFE level.
source `fpc-number`	(Optional) Display details for the specified source FPC. The FPC number is a value from 0 through 7 (depending on platform).
summary	(Optional) Display all switch fabric statistics.

detail Options

none	Display details for all FPCs and PFEs.
destination-fpc `fpc-number`	(Optional) Display details for the specified destination FPC. The FPC number is a value from 0 through 7 (depending on platform).
destination-pfe `pfe-number`	(Optional) Display details for the specified destination packet forwarding engine (PFE). The PFE number is a value from 0 through 15 (depending on platform).
source-fpc `fpc-number`	(Optional) Display details for the specified source FPC. The FPC number is a value from 0 through 7 (depending on platform).
source-pfe `pfe-number`	(Optional) Display details for the specified source PFE. The PFE number is a value from 0 through 15 (depending on platform).
