mode (dynamic or compatible).

Command History
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.

Switch# show mvr
MVR Running: TRUE
MVR multicast VLAN: 1
MVR Max Multicast Groups: 256
MVR Current multicast groups: 0
MVR Global query response time: 5 (tenths of sec)

In the preceding display, the maximum number of multicast groups is fixed at 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 IGMP snooping operation and dynamic MVR membership
on source ports is supported).
