vlan port
Defines a port rule for an existing VLAN. An active mobile port that is specified in a port rule, dynami-
cally joins the VLAN even if traffic on that port does not get learned or matches any VLAN rules. The 
specified port becomes a VLAN member only for the purpose of forwarding broadcast traffic for a VLAN 
on that port. The advantage to this is that traffic from multiple VLANs can flood out on a single port.

Syntax Definitions
vid
VLAN ID number (1–4094). 
slot/port
The slot number for the module and the physical mobile 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).
Defaults

Platforms Supported
OmniSwitch 6400, 6850, 6855, 9000, 9000E
Usage Guidelines
• Use the no form of this command to delete a port rule from the specified VLAN.
• Port rules are for silent devices, such as printers, that require VLAN membership to receive traffic 
forwarded from the VLAN. These devices usually don’t send traffic, so they do not trigger dynamic 
assignment of their mobile ports to a VLAN. 
• Port rules do not classify incoming traffic on the specified mobile port. Incoming traffic is classified for 
VLAN assignment in the same manner as all other mobile port traffic. 
• VLAN assignments that are defined using port rules are exempt from the port’s default VLAN restore 
status. 
• An alternative to port rules is to manually assign a port to a VLAN by using th
 
command. This applies to both mobile and non-mobile ports.
• Rules are only assigned to existing VLANs. Use the vlan command to create a new VLAN.
