Port Mobility Commands
page 21-20 OmniSwitch 6250 CLI Reference Guide November 2009
vlan port mobile
Configures Ethernet ports as mobile ports and enables or disables BPDU ignore. Mobile ports are eligible
for dynamic VLAN assignment, which occurs when mobile port traffic matches a VLAN rule on one or
more VLANs. Typically, mobility is applied to ports that do not send or receive BPDUs. However,
enabling BPDU ignore allows BPDU ports to also participate in dynamic VLAN assignment.
Note. Enabling BPDU ignore is not recommended. In specific cases where it is required, such as connect-
ing legacy networks to port mobility networks, make sure that ignoring BPDUs on a mobile port will not
cause network loops to go undetected. Connectivity problems could also result if a mobile BPDU port
dynamically moves out of its configured default VLAN where it provides traffic flow to and from another
switch.
vlan port mobile slot/port [bpdu ignore {enable | disable}]
vlan no port mobile slot/port
Syntax Definitions
slot/port The slot number for the module and the physical port number on that
module (e.g., 3/1 specifies port 1 on slot 3). To enter multiple slots and
ports in a single command, use a hyphen to specify a range of ports
(e.g., 3/1-16) and a space to specify multiple slots (e.g., 3/1-16 5/10-20
8/2-9).
enable Enables BPDU ignore on a mobile port.
disable Disables BPDU ignore on a mobile port.
Defaults
By default, all ports are non-mobile (fixed) ports.

Usage Guidelines
•
Use the no form of this command to disable mobility on the specified port.
•
Only 10/100 and gigabit Ethernet ports are eligible for mobile port status.
•
Mobile ports can join more than one VLAN. For example, if a device connected to a mobile port sends
IP and Appletalk traffic and VLAN 10 has an IP protocol rule and VLAN 20 has an appletalk protocol
rule, the mobile port and its device dynamically join both VLANs. However, certain rules, such as
MAC address rules, can limit port membership to one VLAN.
