Configuration Mode Commands
This chapter describes how to enable and configure your switch’s features using commands.
For more background information, see the feature specific chapters which proceed the
commands chapters.
44.1 Enabling IGMP Snooping
To enable IGMP snooping on the switch. Enter
igmp-snooping
and press [ENTER]. You
can also set how to treat traffic from an unknown multicast group by typing the
unknown-
multicast-frame
parameter.
Syntax:
igmp-snooping
igmp-snooping 8021p-priority <0-7>
igmp-snooping host-timeout <1-16711450>
igmp-snooping leave-timeout <1-16711450>
igmp-snooping unknown-multicast-frame <drop|flooding>
igmp-snooping reserved-multicast-group <drop|flooding>
where
igmp-snooping
= Enables IGMP snooping on the switch.
8021p-priority
= Sets a priority level (0-7) to which the switch changes the
priority in outgoing IGMP control packets.
host-timeout <1-
16711450>
= Specifies the time out period of the switch with respect to
IGMP report queries. If an IGMP report for a multicast
group was not received for a host-timeout period, from a
specific port, this port is deleted from the member list of
that multicast group.
leave-timeout <1-
16711450>
= Specifies the time that the switch will wait for multicast
members to respond to a leave report. If no response
happens in the timeout period, the switch deletes the port
from the multicast group.
unknown-multicast-
frame <drop|flooding>
= Specifies whether you want to discard packets from
unknown multicast groups or whether you want to forward
them to all ports.
reserved-multicast-
group <drop|flooding>
= Specifies whether you want to discard packets in the
reserved multicast groups or whether you want to forward
them to all ports.
