Usage Guidelines
•
If an instance number is
not
specified, this command displays the Spanning Tree operational status,
path cost, and role for all ports and their associated instances.
•
Specifying an instance number with this command when the switch is running the 1x1 Spanning Tree
operating mode implies a VLAN ID and displays Spanning Tree port information for the associated
VLAN instance.
•
If the switch is running in the flat mode and STP (802.1D) or RSTP (802.1W) is the active protocol,
enter 1 to specify the CIST instance. If MSTP is the active protocol, however, entering 1 for the
instance number is not accepted. In this case, use the
commands instead.
•
The
configured
keyword is only available when an instance number is specified with this command. In
addition, this keyword cannot be used in combination with either the
forwarding
or
blocking
keywords.
