Usage
Information
A group in the include mode should have at least one source address defined. In exclude mode if no
source address is specified, FTOS implicitly assumes all sources are included. If neither include or
exclude is specified, FTOS implicitly assumes a IGMPv2 static join.
Command Limitations
• Only one mode (include or exclude) is permitted per multicast group per interface. To
configure another mode, all sources belonging to the original mode must be unconfigured.
• If a static configuration is present and a packet for the same group arrives on an interface, the
dynamic entry will completely overwrite all the static configuration for the group.
