Verifying spanning tree settings
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.
6. 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,
continue with the next procedure.
Configure RSTP
1. Stop all media access on the K2 SAN.
2. If you have not already done so, telnet to the switch and login with the
administrator username and password.
3. At the switch console command (CLI) prompt, type the following and then press
Enter :
configure
You are now in configuration mode.
4. To set spanning tree to RSTP, type the following and then press Enter :
spanning-tree force-version rstp-operation
This configures spanning tree, but it does not turn spanning tree on.
5. Type the following, then press Enter :
menu
When prompted, save the configuration by pressing the y key.
The main menu opens.
6. Proceed as follows, depending on the STP Enabled setting that you discovered
when you checked spanning tree settings:
• If STP Enabled is already set to Yes, no further configuration is required. Restart
the switch to put changes into effect.
• If STP Enabled is set to No, you must turn spanning tree on using the switch’s
Web interface. Continue with the next procedure.
