Clearing MLD snooping counters and mcache

Field Description

QR	Indicates that the port is a querier.

Clearing MLD snooping counters and mcache

The clear commands for MLD snooping should only be used in troubleshooting situations or when recovering from error conditions.

Clearing MLD counters on all VLANs

To clear MLD snooping error and traffic counters on all VLANs, enter the clear ipv6 multicast counters command.

device#clear ipv6 multicast counters

Syntax: clear ipv6 multicast counters

Clearing the mcache on all VLANs

To clear the mcache on all VLANs, enter the clear ipv6 multicast mcache command.

device#clear ipv6 multicast mcache

Syntax: clear ipv6 multicast mcache

Clearing the mcache on a specific VLAN

To clear the mcache on a specific VLAN, enter the clear ipv6 multicast vlan mcache command.

device#clear ipv6 multicast vlan 10 mcache

Syntax: clear ipv6 multicast vlan vlan-idmcache

The vlan-idparameter specifies the specific VLAN from which to clear the cache.

Clearing traffic counters on a specific VLAN

To clear the traffic counters on a specific VLAN, enter the clear ipv6 multicast vlan traffic command.

device#clear ipv6 multicast vlan 10 traffic

Syntax: clear ipv6 multicast vlan vlan-idtraffic

The vlan-idparameter specifies the specific VLAN from which to clear the traffic counters.
