426 CHAPTER 39: IGMP SNOOPING CONFIGURATION
■ 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.
Multicast Static
Routing Port
Configuration
Introduction 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.
Prerequisites ■ Ports and VLANs involved already exist.
■ Ports to be configured belong to corresponding VLANs.
Configuring a Multicast
Static Routing Port
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.
c
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.
