Multimedia Traffic Control with IP Multicast (IGMP)
CLI: Configuring and Displaying IGMP
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:
Depending on the privilege level, you could use one of the following com-
mands to configure IGMP on VLAN 1 with the above settings:
HPswitch(config)# vlan 1 ip igmp auto a1,a2 forward a3,a4
blocked a5,a6
HPswitch(vlan-1)# ip igmp auto a1,a2 forward a3,a4 blocked
a5,a6
The following command displays the VLAN and per-port configuration result-
ing from the above commands.
HPswitch > show ip igmp vlan 1 config
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: vlan <vid> ip igmp high-priority-forward
Default:
normal
HPswitch (config)# vlan 1 ip igmp
Configures high priority for
high-priority-forward
IGMP traffic on VLAN 1.
HPswitch
(vlan-1)# ip igmp Same as above command,
high-priority-forward
but in the VLAN 1 context
level.
Ports A1-A2 auto 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.)
Ports A3-A4 forward Forward all multicast traffic through this port.
Ports A5-A6 blocked Drop all multicast traffic received from devices on these ports, and
prevent any outgoing multicast traffic from moving through these
ports.
