5. To run the prior software version (K.12.43 in this example), enter this command:

HP Switch(config)#: boot system flash secondary config configK1243.cfg

After rebooting, the switch is running software version K.12.43 and is using the configuration

file that you saved for this software version, configK1243.cfg.

You can also save the K.12.43 configuration file on a TFTP server. To reload the K.12.43

version of the software again, reload the configuration file before doing the reload.

Viewing MSTP statistics

NOTE: SNMP MIB Support for MSTP is a superset of the STP/802.1D and RSTP/802.1w protocols

and uses the MIB objects defined for these two protocols.

Viewing global MSTP status

The following commands display the MSTP statistics for the connections between MST regions in

a network.

Syntax:

show spanning-tree

Displays the switch's global and regional spanning tree status, plus the per-port

spanning tree operation at the regional level. Values for the following parameters

appear only for ports connected to active devices: Designated Bridge, Hello

Time, PtP, and Edge.

Syntax:

show spanning-tree port-list

Dsplays the spanning tree status for the designated ports. You can list data for a

series of ports and port trunks by specifying the first and last port or trunk of any

consecutive series of ports and trunks. For example, to display data for port A20-A24

and trk1, you would use this command: show spanning-tree a20-a42,trk1
