Viewing the Virtual Interface of Multicast VLANs

You can view the multicast VLAN membership of each virtual interface in the switch. In most
cases the virtual interface is the same as a virtual port. However, when multiple services are
set up for a virtual port, then each service may be split into one or more instances.
Type vimcvl and a Virtual Interface Table displays similar to the one that follows. You can also
specify just the slot and port number to narrow the range of ports displayed.
Virtual Interface VLAN Membership
Slot/Intf/Service/Instance Group Member of VLAN#
-------------------------------------------------------------------------------------------------------------------------------
1 /1 /Rtr /1 1 1
1 /1 /Rtr /2 3 23
1 /1 /Rtr /3 3 24
2 /1 /Brg /1 1 23
2 /7 /Brg /1 1 22
4 /1 /Brg /1 1 24
5 /1 /Brg /1 1 22
Slot/Intf/Service/Instance. Specifies the virtual interface for which multicast VLAN information
will be displayed. The Slot is the physical slot location to which the virtual interface maps.
The Intf is the physical port to which the virtual interface maps. The Service is the service type
for this interface. The service type may be a Router (Rtr), Bridge (Brg), Classical IP (CIP), FDDI
Trunk (Trk), or an 802.10 Trunk (T10). Instance is the specific instance of this service type.
These different instances are identified numerically. The first instance of a service type
belonging to a physical port is identified as 1, the second instance is identified as 2, etc.
Group. The Group to which this virtual interface is assigned. The Group is specified when first
creating a multicast VLAN.
Member of VLAN #. The multicast VLANs to which this virtual interface belongs. An interface
may belong to more than one multicast VLAN. For example, if you set up a multicast VLAN for
CNN News and another for NBC News, you may want certain ports to receive both multicast
traffic streams.
