MMRP Commands

This section describes commands you use to configure Multiple MAC Registration Protocol (MMRP) and view configuration information. MMRP provides a mechanism for end-stations and bridges to dynamically register or declare group membership for individual MAC addresses to bridges attached in the same LAN or VLAN.

mmrp (Global Config)

Use the mmrp command in Global Config mode to enable MMRP. MMRP must also be enabled on the individual interfaces.

• Default: disabled
• Format: mmrp
• Mode: Global Config

no mmrp (Global Config)

Use the no mmrp command in Global Config mode to disable MMRP.

• Format: no mmrp
• Mode: Global Config

mmrp periodic state machine

Use the mmrp periodic state machine command in Global Config mode to enable MMRP periodic state machine.

• Default: disabled
• Format: mmrp periodic state machine
• Mode: Global Config

no mmrp periodic state machine

Use the no mmrp periodic state machine command in Global Config mode to disable MMRP periodic state machine.

• Format: no mmrp (Interface Config)
• Mode: Global Config

mmrp (Interface Config)

Use the mmrp command in Interface Config mode on the interface. MMRP can be enabled on physical interfaces or LAG interfaces. When configured on a LAG member port, MMRP is operationally disabled. Enabling MMRP on an interface automatically enables dynamic MFDB entries creation.

• Default: disabled
• Format: mmrp
• Mode: Interface Config

no mmrp (Interface Config)

Use the no mmrp command in Interface Config mode to disable MMRP mode on the interface.

• Format: no mmrp
• Mode: Global Config

clear mmrp statistics

Use the clear mmrp command in Privileged EXEC mode to clear MMRP statistics of one or all interfaces.

• Format: clear mmrp statistics [unit/slot/port|all]
• Mode: Privileged EXEC
• unit/slot/port: If used with unit/slot/port parameter, the command clears MMRP statistics for the given interface.
• all: If the all parameter is specified, the command clears MMRP statistics for all the interfaces.

show mmrp

Use the show mmrp command in Privileged EXEC mode to display the status of the MMRP mode.

• Format: show mmrp [summary | interface [unit/slot/port | summary]]
• Mode: Privileged EXEC

The display parameters for above command are:

• summary: If used with the summary parameter, the command displays global MMRP information.
• interface: If the interface is specified, the command displays the MMRP mode of that interface.
• summary: If the summary option is specified, the command shows a table containing MMRP global mode for all interfaces.
