9.2.9 IGMP State Limit
You can use IGMP State Limit feature to limit the number of IGMP states that can be
joined to a router on a per-interface or global level. Membership reports exceeding the
configured limits are not entered into the IGMP cache and traffic for the excess
membership reports is not forwarded.
To configure the IGMP State limit globally, use the following command.
ip igmp limit <1-2097152>
[except {<1-99> | <1300-1999> |
WORD}]
Limits the number of IGMP membership reports
globally:
1-2097152: the number of IGMP states allowed on a
router
1-99: IP standard access list
1300-1999: IP standard access list (expanded)
WORD: access list name
Disables the globally configured IGMP state limit.
If you want to exclude certain groups or channels from being counted against the IGMP
limit so that they can be joined to an interface, use except option.
