Defining VLAN Rules

Configuring VLAN Rule Definitions

OmniSwitch AOS Release 6 Network Configuration Guide

page 8-11

• When an active device is disconnected from a mobile port and connected to a fixed port, the source 

MAC address of that device is not learned on the fixed port until the MAC address has aged out and no 
longer appears on the mobile port.

• When a VLAN is administratively disabled, static 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 VLAN is deleted from the switch configuration, all rules defined for that VLAN are automati-

cally removed and any static or dynamic port assignments are dropped.

• It is possible to define MAC-port-IP and MAC-port binding rules for Authenticated VLANs 

(AVLANs). However, these rules are not active until the avlan port-bound command is issued for the 
AVLAN. Note that these rules only apply to traffic received on authenticated ports. See 

 for more information.

Refer to the following sections (listed in the order of rule precedence) for instructions on how to define 
each type of VLAN rule:

To display a list of VLAN rules already configured on the switch, use the 

 command. For 

more information about this command, refer to the OmniSwitch CLI Reference Guide.

DHCP MAC address rules capture DHCP frames that contain a source MAC address that matches the 
MAC address specified in the rule. See 

 for an exam-

ple of how DHCP port rules are used in a typical network configuration.

To define a DHCP MAC address rule, enter vlan followed by an existing VLAN ID then dhcp mac 
followed by a valid MAC address. For example, the following command defines a DHCP MAC address 
rule for VLAN 255:

-> vlan 255 dhcp mac 00:00:da:59:0c:11
