■

When you configure IGMP Snooping fast leave on aggregation ports, the 
configuration takes effect only on primary aggregation ports.

■

If you add an IGMP V1 host of the same multicast group to the port, the switch 
does not remove the port when the port receives an IGMP Leave packet of the 
multicast group even you enable IGMP Snooping fast leave for the port.

By configuring a port in a VLAN to be a static routing port, you can enable IGMP 
packets to be transparently transmitted through the port, meeting the 
requirements of specific networks.

■

Ports and VLANs involved already exist.

■

Ports to be configured belong to corresponding VLANs.

You can configure a port in a VLAN to be a static routing port in VLAN view.

You can also configure a port in a VLAN to be a static routing port in the 
corresponding Ethernet port view.

■

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.
