Brocade Communications Systems IPMC5000PEF manual Example configuration

Displaying an IGMP SSM mapping information

Theacl-idvariable specifies the ACL ID that contains the group multicast address.

The source-addressvariable specifies the source address that you want to map to the group multicast address specified in the ACL.

The no option is used to delete a previously configured SSM map.

Example configuration

In the following example configuration, one extended ACL and two standard ACLs are defined with group multicast addresses. The ip igmp ssm-mapcommands are configured to map the ACLs to source addresses and to enable the feature on the router.

device(config)# access-list 20 host 239.1.1.1 device(config)# access-list 20 permit 224.1.1.0 0.0.0.225 device(config)# access-list 100 permit any host 232.1.1.1 device(config)# ip igmp ssm-map 20 1.1.1.1 device(config)# ip igmp ssm-map 20 2.2.2.2 device(config)# ip igmp ssm-map 100 1.1.1.1 device(config)# ip igmp ssm-map enable

Displaying an IGMP SSM mapping information

The show ip igmp ssm-mapcommand displays the association between a configured ACL and source address mapped to it, as shown in the following.

device# show ip igmp ssm-map
