Usage Guidelines
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output
do not appear, but the lines that contain Output appear.
Examples
This is an example of output from the show mvr command:
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)
MVR Mode: compatible
In the previous example, the maximum number of multicast groups is 256. The MVR mode is either
compatible (for interoperability with Catalyst 2900 XL and Catalyst 3500 XL switches) or dynamic
(where operation is consistent with Internet Group Management Protocol [IGMP] snooping operation,
and dynamic MVR membership on source ports is supported).
