Platforms Supported
OmniSwitch 6250
Usage Guidelines
•
If an instance number is not specified, this command displays the Spanning Tree status, protocol, and
priority values for all 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 bridge 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
show spantree cist or show spantree msti
commands instead.
