Command Reference
forbid
The “forbid” mode excludes the port as a multicast router port.
igmpsnoop port(s) port_list group { ip_group | all } mode { normal |
fixed | forbid } VID ID
used to recognize interested member ports and creates a
separate broadcast domain for each multicast group.
Example
6000 switch>#>igmpsnoop ports 1 2 3 group 239.147.6.99 mode fixed VID 1
Port 1, 2, 3 are included as members of IP multicast group
239.147.6.99 even when an IGMP membership report for the
group has not been received on those ports.
6000 switch>#>igmpsnoop ports 1 2 3 group all mode forbid VID
If the forbid keyword is substituted in the above command,
ports 1, 2, and 3 are excluded from IP multicast group even
though the system has received an IGMP membership report
for the same group from those ports. This is a security feature
to disallow an end station from participating in a particular
multicast session. Instead of a particular IP multicast group,
the all keyword implies all IP multicast groups.
igmpsnoop port { control | data } reset { VID ID | all }
resets the ports to normal mode.
Example
To reset all control ports on VID 1 to normal mode.
6000 switch>#>igmpsnoop port control reset VID 1
To reset all data ports in the system (all VLANs) to normal mode.
6000 switch>#>igmpsnoop port data reset all
igmpsnoop { set | print } agetime { value (secs) }
set or display the aging time used to specify the time
acceptable (in seconds) between IGMP queries since the
switch last received an IGMP query from the multicast server.
the range is from 330 to 500 seconds. The default is 330
seconds.
Example
Sets the agetime.
6000 switch>#>igmpsnoop set agetime 350
Displays the previous configured aging value.
6000 switch>#>igmpsnoop print agetime
250
