Configuring GMRP on the Switch
Enabling GMRP Globally
Note You cannot enable GMRP if IGMP snooping is enabled.
To enable GMRP globally, perform this task in privileged mode:
This example shows how to enable GMRP globally and verify the configuration:
Console> (enable) set gmrp enable
GMRP enabled.
Console> (enable) show gmrp configuration
Global GMRP Configuration:
GMRP Feature is currently enabled on this switch.
GMRP Timers (milliseconds):
Join = 200
Leave = 600
LeaveAll = 10000
Port based GMRP Configuration:
Port GMRP Status Registration ForwardAll
-------------------------------------------- ----------- ------------ ----------
1/1-2,3/1,6/1-48,7/1-24 Enabled Normal Disabled
Console> (enable)
Enabling GMRP on Individual Switch Ports
Note You can change the per-port GMRP configuration regardless of whether GMRP is enabled globally.
However, GMRP will not function on any ports until you enable it globally. For information on
configuring GMRP globally, see the “Enabling GMRP Globally” section on page 51-21.
To enable GMRP on the individual switch ports, perform this task in privileged mode:
This example shows how to enable GMRP on port 6/12 and verify the configuration:
Console> (enable) set port gmrp enable 6/12
GMRP enabled on port 6/12.
Console> (enable) show gmrp configuration
Global GMRP Configuration:
GMRP Feature is currently enabled on this switch.
GMRP Timers (milliseconds):
Join = 200
Leave = 600
LeaveAll = 10000
