Port Mobility Commands
OmniSwitch 6250 CLI Reference Guide November 2009 page 21-21
• When a VLAN is administratively disabled, manual port and dynamic mobile port assignments are
retained but traffic on these ports is not forwarded. However, VLAN rules remain active and continue
to classify mobile port traffic for VLAN membership.
• When a BPDU is received on a mobile port and BPDU ignore is disabled, the port is changed to a fixed
(non-mobile) port that is associated only with its configured default VLAN. Also, the BPDU port
participates in the Spanning Tree algorithm. When BPDU ignore is enabled, a mobile port that receives
a BPDU remains mobile and is not included in Spanning Tree topology calculations.
• Enabling mobility on an active port that sends or receives BPDU (e.g. ports that connect two switches
and Spanning Tree is enabled on both the ports and their assigned VLANs) is not allowed. If mobility
is required on this type of port, enable mobility and the BPDU ignore flag when the port is not active.

-> vlan port mobile 6/12-16 authenticate disable
-> vlan no port mobile 2/1
