Check spanning tree settings
1. If you have not already done so, telnet to the switch and login with the administrator username
and password.
2. At the switch console command (CLI) prompt, type the following and press Enter :
show spanning-tree
Spanning tree information is displayed.
3. Check the spanning tree information and make sure that settings are correct, as follows:
STP Enabled: Yes
Force Version: RSTP-operation
4. If settings are correct, no further configuration is required.
5. If settings are not correct, you have the following options:
• If you have one switch only and the switch is not connected to any other switches, these
spanning tree settings are recommended, but not required. You should make the correct
settings at your next opportunity when it is convenient.
• If your switch is connected to another switch, either because you have a multi-switch K2
SAN or for any other reason, these spanning tree settings are required. You must correct your
spanning tree settings as soon as possible.
Changing spanning tree settings requires a restart of the switch, so you must make the settings while
the K2 SAN is offline. When you can take your system offline, configure RSTP (spanning tree).
