PIM Sparse

NOTE

If you have configured interfaces for standard PIM (dense mode) on the Layer 3 switch, statistics for

these interfaces are listed first by the display.

This display shows the following information.

Clearing the PIM message counters

You can clear the PIM message counters using the clear pim traffic command.

Brocade# clear pim traffic

Syntax: clear pim traffic

Displaying and clearing PIM errors

If you want to determine how many PIM errors there are on the device, enter the show ip pim error

command.

Brocade# show ip pim error

**** Warning counter pim route change = 1

HW tagged replication enabled, SW processed pkts 0

Syntax: show ip pim error

This command displays the number of warnings and non-zero PIM errors on the device. This count

can increase during transition periods such as reboots and topology changes; however, if the

device is stable, the number of errors should not increase. If warnings keep increasing in a stable

topology, then there may be a configuration error or problems on the device.

To clear the counter for PIM errors, enter the clear pim counters command.

Brocade#clear pim counters

Syntax: clear pim counters
