VLAN Management Commands
OmniSwitch 6250 CLI Reference Guide November 2009 page 22-5
• When STP is disabled on a VLAN, it remains disabled even if the switch Spanning Tree operating
mode is set to 1x1 (one STP instance per VLAN). In addition, all active ports for the disabled VLAN
remain in a forwarding state in both the 1x1 and flat Spanning Tree modes.
• If a switch is running in the flat Spanning Tree mode, disabling Spanning Tree on VLAN 1 disables the
instance across all VLANs. Disabling STP on any other VLAN disables the instance only for that
VLAN.
