10.4.6.2.5 ip igmp snooping max-response-time
This command sets the IGMP Maximum Response time on the system. The Maximum Response time is
the amount of time in seconds that a switch will wait after sending a query on an interface because it did
not receive a report for a particular group in that interface. This value must be less than the IGMP Query
Interval time value. The range is 1 to 25 seconds.
Syntax
ip igmp snooping max-response-time <sec>
no ip igmp snooping max-response-time
<sec> - Max time (Range: 1 - 25).
no - This command sets the IGMP Maximum Response time on the system to 10 seconds.
Default Setting
10 seconds
Command Mode
Global Config, Interface Config.
10.4.6.2.6 ip igmp snooping fast-leave
This command enables or disables IGMP Snooping fast-leave admin mode on a selected interface or on
all interfaces. Enabling fast-leave allows the switch to immediately remove the layer 2 LAN interface
from its forwarding table entry upon receiving an IGMP leave message for that multicast group without
first sending out MAC-based general queries to the interface(s).
Fast-leave admin mode should be enabled only on VLANs where only one host is connected to each
layer 2 LAN port, to prevent the inadvertent dropping of the other hosts that were connected to the same
layer 2 LAN port but were still interested in receiving multicast traffic directed to that group. Also,
fast-leave processing is supported only with IGMP version 2 hosts.
Syntax
ip igmp snooping fast-leave
no ip igmp snooping fast-leave
no - This command disables IGMP Snooping fast-leave admin mode.
Default Setting
Disabled
Command Mode
Global Config, Interface Config.
