Subject: ip igmp limit number [except access-list]
Hi,
I am trying to understand the logic of the access-list along with the *ip
igmp limit* *number* command.
i.e *ip igmp limit* *number* [*except **access-list*]
I am not able to understand the except logic as to whether the groups
permitted by the access-list are not counted towards the total or is it
otherwise.
If someone can clarify this to me please.
Regards
Shamin**
