Hello Pramod,

I may be wrong but the right show command is

sh spanning-tree mst configuration

that provides the expected output

see table 23-8

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/spantree.html#wp1102891

there is a

sh spanning-tree mst

but it expects a parameter for MST instance.

This could be seen as a little bug: it should answer that the command is not recognized for the missing parameter.

Hope to help

Giuseppe
