Usage Guidelines
•
If a vlan_id number is not specified, this command displays the Spanning Tree port operational status,
path cost, and role values for all VLAN instances.
•
Specifying a range of VLAN IDs is also allowed. Use a hyphen to indicate a contiguous range (e.g.,
show spantree vlan 10-15 ports ). Note that only one VLAN entry—a single VLAN ID or a range of
VLAN IDs— is allowed with this command. Multiple entries are not accepted.
•
This command displays Spanning Tree port information for a VLAN instance regardless of which
mode (per-VLAN or flat) is active for the switch.
•
Note that minimal information is displayed when this command is used in the flat mode, as VLAN
instances are not active in this mode.
•
The configured keyword is only available when a VLAN ID is specified with this command. In addi-
tion, this keyword cannot be used in combination with either the forwarding or blocking keywords.
