Configure Restricted Group Registration

By default, port-level restricted group registration is disabled. If this feature is enabled, then the multicast group attribute or service requirement attribute is learned dynamically on a port, only if the specific multicast group attribute or service requirement attribute is statically configured in the switch. If restricted group registration rules are disabled, then the GMRP packets are processed normally, and the multicast group attribute or service requirement attributes are learned dynamically, even if they are not statically configured in the switch. See Default Settings for the example topology for this procedure.

1. In switch A, configure the static multicast MAC address.

   SEFOS# configure terminal
   SEFOS(config)# mac-address-table static multicast 01:02:03:04:05:06 vlan 1 interface extreme-ethernet 0/3
   SEFOS(config)# end

2. Review the output of the static multicast table.

   SEFOS# show mac-address-table static multicast
   Static Multicast Table
   ----------------------
   VLAN            : 1
   Mac Address     : 01:02:03:04:05:06
   Receive Port    : 
   Member Ports    : Ex0/3
   Forbidden Ports :
   Status          : Permanent
   ------------------------------------------------

3. Review the statically configured multicast entry in switch A.

   SEFOS# show mac-address-table
   VLAN    Mac Address         Type     Ports
   ----    -----------         ----     -----
   1       00:02:02:03:04:01   Learnt   Ex0/3 (Switch B port Ex2 mac address)
   1       01:02:03:04:05:06   Static   Ex0/1
   Total Mac Addresses displayed: 2

4. Review the output in switch B.

   SEFOS# show mac-address-table
   VLAN  Mac Address         Type     Ports
   ----  -----------         ----     -----
   1     00:01:02:03:04:02   Learnt   Ex0/3 (In Switch A, port Ex 0/3 Mac addr)
   1     01:02:03:04:05:06   Learnt   Ex0/3 (Switch A group mac addr)
    
   Total Mac Addresses displayed: 2

5. Enable restricted group registration in switch B.

   SEFOS# configure terminal
   SEFOS(config)# interface extreme-ethernet 0/3
   SEFOS(config-if)# group restricted enable
   SEFOS(config-if)# end

6. Review the configuration details after enabling restricted group registration.

   SEFOS# show mac-address-table
   VLAN    Mac Address         Type     Ports
   ----    -----------         ----     -----
   1       00:01:02:03:04:02   Learnt   Ex0/3
    
   Total Mac Addresses displayed: 1

7. Create the static multicast MAC address.

   SEFOS# configure terminal
   SEFOS(config)# mac-address-table static multicast 01:02:03:04:05:06 vlan 1 interface extreme-ethernet 0/3
   SEFOS(config)# end

8. Review the MAC address table details.

   SEFOS# show mac-address-table
   VLAN    Mac Address         Type     Ports
   ----    -----------         ----     -----
   1       00:01:02:03:04:02   Learnt   Ex0/3
   1       01:02:03:04:05:06   Static   Ex0/1,Ex0/2
   Total Mac Addresses displayed: 2
