Configuring Source Specific Multicast Mapping
The Source Specific Multicast (SSM) mapping feature supports SSM transition when supporting SSM on the
end system is impossible or unwanted due to administrative or technical reasons. You can use SSM mapping
to leverage SSM for video delivery to legacy STBs that do not support IGMPv3 or for applications that do
not use the IGMPv3 host stack.
Configuring Static SSM Mapping (CLI)

6.
Repeat Step 4 to configure additional static SSM mappings, if required.
7.
end

Device> enable
•
Enter your password if prompted.
Enters the global configuration mode.configure terminal
Example:
Device# configure terminal
Step 2
Enables SSM mapping for groups in the configured SSM range.ip igmp ssm-map enable
Step 3
Example:
