The AlliedWare Plus commands let you change only the MSTP
parameters listed above. To change the other parameters, use the
standard command or another management interface.
Example
This example sets the region’s revision level to 10 and its name to
‘sw10a:’
awplus> enable
awplus# configure terminal
awplus(config)# spanning-tree mst configuration
awplus(config-mst)# revision 10
awplus(config-mst)# region sw10a
The FORCEVERSION command sets the MSTP mode. Settings 1 and 2
are STP compatible and force STP compatible, respectively. These
settings are identical. Setting 3 is normal MSTP. These commands set the
switch to STP compatible:
awplus> enable
awplus# configure terminal
awplus(config)# spanning-tree forceversion 1
