Cisco Systems RJ-45-to-AUX manual Disabling Gmrp, Enabling Gmrp on Individual Ports

Disabling GMRP

To disable GMRP globally, use the following command:

Coriolis> (enable) set gmrp disable

GMRP disabled.

Enabling GMRP on Individual Ports

You can enable GMRP on a per−port basis using this command:

Coriolis> (enable) set port gmrp enable 2/1−12

GMRP enabled on ports 2/1−12.

But don’t be fooled—the switch will let you configure GMRP on a per−port basis, but it will not work unless you enable it globally.

Disabling GMRP on Individual Ports

To disable GMRP on each port, use the following command:

Coriolis> (enable) set port gmrp disable 2/1−12

GMRP disabled on ports 2/1−12.

Enabling GMRP Forward−All

When GMRP forward−all is enabled, a copy of all multicast traffic is forwarded to that port. You may want to use this feature when a probe or network analyzer is connected to a port. Cisco’s documentation recommends that you enable forward−all on any port that is connected to a router. Use this command to enable forward−all:

Coriolis> (enable) set gmrp fwdall enable 2/1

GMRP Forward All groups option enabled on port 2/1.

Disabling GMRP Forward−All

To disable GMRP forward−all on a port, use the following command:

Coriolis> (enable) set gmrp fwdall disable 2/1

GMRP Forward All groups option disabled on port 2/1.

Configuring GMRP Registration

GMRP registration has three modes:

∙Normal mode—Allows dynamic GMRP multicast registration and de−registration on the port.

∙Fixed mode—Registers all multicast group on all ports to this single port and ignores any subsequent registration and de−registration on other ports. To de−register any multicast group, you must first return the port to Normal mode.

∙Forbidden mode—Un−registers all GMRP multicasts and will not accept any GMRP multicast registration on that port.

To configure Normal mode, use the following command:

Coriolis> (enable) set gmrp registration normal 2/1

GMRP Registration is set normal on port 2/1.
