Displaying MVR
You can display MVR information for the switch or for a specified interfaces.
Beginning in privileged EXEC mode, use the commands in Table 11-3 to display MVR configuration:

Switch# show mvr
MVR Running: TRUE
MVR multicast vlan: 1
MVR Max Multicast Groups: 256
MVR Current multicast groups: 256
MVR Global query response time: 5 (tenths of sec)

Table 11-4 Commands for Displaying MVR Information
show mvr Displays MVR status and values for the switch—whether MVR is enabled or disabled,
the multicast VLAN, the number of multicast groups (always 256 for the Catalyst 2950
switch), the query response time, and the MVR mode.
show mvr interface [interface-id]
[members [vlan vlan-id]]
Displays all MVR interfaces and their MVR configurations.
When a specific interface is entered, displays this information:
• Type—Receiver or Source
• Status—One of these:
– Active means that the port is part of a VLAN.
– Up/Down means that the port is forwarding or nonforwarding.
– Inactive means that the port is not part of any VLAN.
• Immediate Leave—Enabled or Disabled
If the members keyword is entered, displays all multicast group members on this port or,
if a VLAN identification is entered, all multicast group members on the VLAN.
show mvr members [ip-address] Displays all receiver ports that are members of any IP multicast group or the specified IP
multicast group IP address.
