    Clearing the Blocked Status of a Spanning-Tree Instance Interface

    To clear the blocked status of a spanning-tree instance interface:

    • Use the clear error bpdu operational mode command.

      user@host> clear error bpdu interface interface-name

    Note: When you configure BPDU protection on individual interfaces (as opposed to on all the edge ports of the bridge), you can use the disable-timeout seconds option to specify that a blocked interface is automatically cleared after the specified time interval elapses (unless the interval is 0). For configuration details, see Configuring BPDU Protection on Individual Interfaces.
