HP 6125G Configuration Guide

Configuration guidelines
• 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:
Ste
p
Command
Remarks
1. Enter system view.
system-view N/A
2. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.
interface interface-type
interface-number
Use either command.
3. Configure the port as a static
member port.
igmp-snooping static-group
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 a port as a simulated member host
Generally, a host that runs IGMP can respond to IGMP queries that the IGMP querier sends. If a host fails
to respond, the multicast router might deem that no member of this multicast group exists on the network
segment, and removes the corresponding forwarding path.
To avoid this situation, you can configure the port as a simulated member host for a multicast group. A
simulated host is equivalent to an independent host. For example, when a simulated member host
receives an IGMP query, it gives a response separately. Therefore, the switch can continue receiving
multicast data.
A simulated host acts like a real host in the following ways:
• When a port is configured as a simulated member host, the switch sends an unsolicited IGMP
report through the port, and can respond to IGMP general queries with IGMP reports through the
port.
• When the simulated joining function is disabled on a port, the switch sends an IGMP leave
message through the port.
Unlike a static member port, a port that you configure as a simulated member host ages out like a
dynamic member port.
