Syntax

show system resource-monitor ( fpc | summary )
<slot slot-number>

Description

Display the utilization of memory resources on the Packet Forwarding Engines for all FPCs or a specific FPC. The filter memory denotes the filter counter memory used for firewall filter counters. The asterisk (*) displayed next to each of the memory regions denotes the ones for which the configured threshold is being currently exceeded.

Options

slot slot-number

Display the Junos OS utilization information of memory resources for the specified slot number in which the FPC (or MPC) is installed.

Note:

On the MX80 router, the MPCs are built into the chassis and are represented in the CLI as either FPC 0 or FPC 1. This command supports only FPC 1 for the MX80 router.

Additional Information

The filter memory denotes the filter counter memory used for firewall filter counters. From the Ukern perspective, MPC5E contains only one Packet Forwarding Engine instance. The show chassis fabric plane command output displays the state of fabric plane connections to the Packet Forwarding Engine. Because two Packet Forwarding Engines exist, you notice PFE-0 and PFE-1 in the output.
