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. 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:
port-group manual
port-group-name
Use either approach.
3. Configure the port as a
static member port.

group-address [ source-ip
source-address ] vlan vlan-id
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.
