IGMP Snooping Commands
14 – 381
Defaults The pseudo-querier is disabled on all VLANs by default.
Access Enabled.
History Introduced in MSS Version 1.0.
Usage Trapeze Networks recommends that you use the pseudo-querier only when the VLAN
contains local multicast traffic sources and no multicast router is servicing the subnet.
Examples The following example enables the pseudo-querier on the orange VLAN:
MX# set igmp querier enable vlan orange
success: change accepted.
See Also show igmp querier on page 14-386
set igmp receiver
Adds or removes a network port in the list of ports on which an MX switch forwards traffic to
multicast receivers. Static multicast receiver ports are immediately added to or removed from the
list of receiver ports and do not age out.
Syntax set igmp receiver port port-list {enable | disable}
Defaults By default, no ports are static multicast receiver ports.
Access Enabled.
History Introduced in MSS Version 1.0.
Usage You cannot add MP access ports or wired authentication ports as static multicast ports.
However, MSS can dynamically add these port types to the list of multicast ports based on
multicast traffic.
Examples The following command adds port 7 as a static multicast receiver port:
MX# set igmp receiver port 7 enable
success: change accepted.
The following command removes port 7 from the list of static multicast receiver ports:
MX# set igmp receiver port 7 disable
success: change accepted.
See Also show igmp receiver-table on page 14-387
set igmp rv
Changes the robustness value for one VLAN or all VLANs on an MX switch. Robustness adjusts
the IGMP timers to the amount of traffic loss that occurs on the network.
disable Disables the pseudo-querier.
vlan vlan-id
VLAN name or number. If you do not specify a VLAN, the
pseudo-querier is enabled or disabled on all VLANs.
port port-list
Network port list. MSS adds the specified ports to the list of static multicast receiver
ports.
enable Adds the port to the list of static multicast receiver ports.
disable Removes the port from the list of static multicast receiver ports.
