device-name(cfg protocol)#
spanning-tree line-error-detect
The spanning-tree line-error-detect enable command, in Protocol Configuration mode,
switches the device to using the existing alternate (backup) link instead of the current link,
when the CRC errors on the line reach critical level. The error level is considered critical
when the CRC error rate exceeds 1% for a 3-seconds interval. The command triggers
reconfiguring of the Spanning Tree or the Rapid Spanning Tree, so it is effective only when
either STP or RSTP is enabled.
The spanning-tree line-error-detect disable command disables detecting of CRC errors.

spanning-tree all
The spanning-tree all command, in Interface Configuration mode, displays the current status
of spanning-tree parameters for all the switch's logical interfaces. The command is equivalent
