Configuring static ports
If all hosts attached to a port are interested in the multicast data addressed to a particular multicast group
or the multicast data that a particular multicast source sends to a particular group, you can configure a
static (*, G) or (S, G) entry for the port. That is, you configure the port as a static member port of the
specified group or the specified source and group.
You can also configure a port of the AC to be a static router port, through which the AC can forward all
the multicast traffic that it received.
Configuration guidelines
•
A static (S, G) entry for a port takes effect only if a valid multicast source address is specified and
IGMPv3 snooping is running on the AC.
•
A static member port does not respond to queries from the IGMP querier. When you configure a
port as a static member port or cancel this configuration on the port, the port does not send an
unsolicited IGMP report or an IGMP leave message.
•
Static member ports and static router ports never age out. To remove such a port, use the
corresponding undo command.
Configuration procedure
To configure static ports:
Step Command
Remarks
1.
Enter system view.

N/A
2.
Enter Layer 2 Ethernet
interface view, Layer 2
aggregate interface view,
or port group view.
•
Enter Layer 2 Ethernet interface
view or Layer 2 aggregate
interface view:
interface interface-type
interface-number
•
Enter port group view:

Use either approach.
3.
Configure the port as a
static member port.
igmp-snooping static-group
group-address [ source-ip

No static member ports exist by
default.
4.
Configure the port as a
static router port.
igmp-snooping static-router-port vlan
vlan-id
No static router ports exist by
default.
Configuring simulated joining
Generally, an IGMP-enabled host can respond to IGMP queries that the IGMP querier sends. If a host
fails to respond, the multicast router deems that no member of this multicast group exists on the network
segment, and removes the corresponding forwarding path.
