Usage Guidelines
• If a vid 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 1x1 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 is an explicit Spanning Tree command that displays Spanning Tree port information for a VLAN
instance regardless of which mode (1x1 or flat) is active on 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 an instance number is specified with this command. In
addition, this keyword cannot be used in combination with either the forwarding or blocking
keywords.
