Fast Leave Status (cisFastLeaveEnabled)

Indicates whether the Fast-Leave mechanism has been enabled for the system. If Fast-Leave is enabled, IGMP Snooping will prune the port on which an IGMP leave message has been received without waiting for the Group Specific Query to determine whether there are any more hosts on that port for that group. If the value of cisV3ProcessEnabledOperStatus is "false", this object will have no effect.

IGMP v1/v2 Snooping Protocol:

Snooping Status (cisIgmpSnoopingEnabled)

Indicates whether IGMP Snooping has been enabled for the system.

IGMP v3 Snooping Protocol:

Administrative Status (cisV3ProcessEnabledAdminStatus)

Indicates the administrative status of IGMP version 3 processing in the system. When the IGMP protocol has been enabled, a system will process:

- IGMP version 3 messages when this object is set to "true".

- IGMP version 1/version 2 messages when this object is set to "false".

Operational Status (cisV3ProcessEnabledOperStatus)

Indicates the current operational status of IGMP version 3 processing in the system. The value of this object is "true" when the system is operating in IGMP version 3.

Fast Block Status (cisFastBlockEnabled)

Indicates whether the Fast-Block mechanism has been enabled for the system. This object only has an effect when the value of cisV3ProcessEnabledOperStatus is "true".
