spantree bpdu-switching
Enables or disables the switching of Spanning Tree BPDU for VLAN and CIST instances if the switch is
running in the per-VLAN mode.
spantree {vlan vlan_id | cist} bpdu-switching {enable | disable}
Syntax Definitions
vlan_id An existing VLAN ID number.
enable Enables BPDU switching for the specified instance.
disable Disables BPDU switching for the specified instance.
Defaults
By default, BPDU switching is disabled for VLAN or CIST instance.
Platforms Supported
OmniSwitch 10K
Usage Guidelines
•
Specifying the BPDU switching status for a VLAN does not depend on the current VLAN Spanning
Tree status. For example, setting the BPDU switching status to enabled is allowed on a VLAN that also
has Spanning Tree enabled.
•
Use the vlan parameter along with the vlan_id to enable or disable BPDU switching for a particular
VLAN.
•
Use the cist parameter to enable or disable BPDU switching for the CIST instance.
