Displaying And Maintaining Igmp Snooping - H3C S9500 Series Operation Manual

Operation Manual – Multicast Protocol
H3C S9500 Series Routing Switches
Caution:
You will fail to configure a port to be a static routing port if the port identified by the
port-number argument does not exist, or the port does not belong to the VLAN.
You will fail to configure a port to be a static routing port if the VLAN identified by the
vlan-id argument does not exist or the port does not belong to the VLAN.
You can configure multiple ports in a VLAN to be static routing ports by performing
the above configuration repeatedly. The newly configured ports do not replace the
existing static routing ports.
When a trunk port belongs to multiple VLANs, this port can be configured as the
static routing port for multiple VLANs.
Static routing ports can be configured in VLAN view or Ethernet port view. However,
you can verify the configured static routing ports only by executing the display this
command in Ethernet port view.
The configuration of a static routing port takes effect on the current port only, no
matter whether the current port is an aggregated port or not. To configure all ports in
an aggregation group as static routing ports, you can enable the static routing port
function on all the ports in the aggregation group.

2.4 Displaying and Maintaining IGMP Snooping

After the above configuration, execute display command in any view to display the
running of the IGMP Snooping configuration, and to verify the effect of the
configuration.
Use the debugging mpm command in user view to carry out multicast debugging.
