Freezing MSTP (CLI)
You can freeze MSTP in the unit. When MSTP is frozen, BPDUs are neither transmitted nor processed, and all port
states are maintained as they were before MSTP was frozen.
To freeze MSTP, enter the following command in root view:
root> ethernet mstp mstp-freeze
To unfreeze MSTP, enter the following command in root view:
root> ethernet mstp mstp-defreeze
To display whether MSTP is or is not currently frozen in the unit, enter the following command in root view:
root> ethernet mstp show-mstp-frozen
Resetting the MSTP Stack (CLI)
To reset MSTP on the unit, enter the following command in root view:
root> ethernet mstp mstp-reset
Handling Signal Degrade (SD) Failures (CLI)
Signal Degrade failures (SD) can either be ignored or treated the same as SF, which means an SD failure triggers a
topology change.
Note
This feature is planned for future release.
To determine how SD failures are treated, enter the following command in root view:
root> ethernet mstp set sd-handling <sd-handling>
