Syntax: show fabric counters [module bay/slot]

module bay/slot

Identifies a module whose fabric channels are displayed.

Description: The Avici router employs a three dimensional toroidal mesh interconnection between each line card installed into the backplane. Each routing module forms the intersection of three bi-directional rings in three dimensions:

Packets are forwarded from module to module along these links. Packets are inserted into and extracted from the fabric along two additional links:

Use the show fabric counters command to display the number of packets inserted into the fabric, extracted from the fabric, and forwarded to another module along the fabric links for the module.

Use the show fabric counters command with no arguments to display fabric counters for all modules.

Use the show fabric counters module bay/slot command to display fabric counters for the specified module.

Factory Default: None.

Command Mode: Executive and privileged.
