Configuring Per-Port IGMP Packet Control. Use this command in the
VLAN context to specify how each port should handle IGMP traffic.
Syntax: vlan <vid> ip igmp
[auto <port-list> | blocked <port-list> | forward <port-list>]
Default: auto
For example, suppose you wanted to configure IGMP as follows for VLAN 1
on the 100/1000T ports on a module in slot 1:
Ports A1-A2 auto
Ports A3-A4 forward
Ports A5-A6 blocked
Depending on the privilege level, you could use one of the following com-
mands to configure IGMP on VLAN 1 with the above settings:
The following command displays the VLAN and per-port configuration result-
ing from the above commands.
Configuring IGMP Traffic Priority. This command assigns "high" priority
to IGMP traffic or returns a high-priority setting to "normal" priority. (The
traffic will be serviced at its inbound priority.)
Syntax:
<vid>
normal
Default:
Multimedia Traffic Control with IP Multicast (IGMP)
Filter multicast traffic. Forward IGMP traffic to hosts on these ports
that belong to the multicast group for which the traffic is intended.
(Also forward any multicast traffic through any of these ports that
is connected to a multicast router.)
Forward all multicast traffic through this port.
Drop all multicast traffic received from devices on these ports, and
prevent any outgoing multicast traffic from moving through these
ports.
CLI: Configuring and Displaying IGMP
Configures high priority for
IGMP traffic on VLAN 1.
Same as above command,
but in the VLAN 1 context
level.
