MSTP for ENCS 5400 8-Port Switch
Multiple Spanning Trees Protocol (MSTP) is introduced to the 8-port switch on ENCS 5400. MSTP enables multiple VLANs to be mapped to the same spanning tree instance, which reduces the number of spanning-tree instances needed to support a large number of VLANs.
ENCS 5400 switch supports 15 instances. Each spanning tree instance is identified by an instance ID from 1 to 15.

To configure the maximum hop count for all MST instances:
configure terminal
switch
spanning-tree mst max-hops 10
commit
Use the show switch spanning-tree mstp configuration global command to verify the MSTP configuration.
nfvis# show switch spanning-tree mstp configuration global
spanning-tree mstp configuration global name transit-net
spanning-tree mstp configuration global revision 2
spanning-tree mstp configuration global max-hops 20
Use the show switch spanning-tree mstp configuration instance-list command to verify the MSTP instance configuration.
nfvis# show switch spanning-tree mstp configuration instance-list
