Defining VLAN Rules

Defining Port Rules

Port rules do not require mobile port traffic to trigger dynamic assignment. When this type of rule is
defined, the specified mobile port is immediately assigned to the specified VLAN. As a result, port rules
are often used for silent network devices, which do not trigger dynamic assignment because they do not
send traffic.
Port rules only apply to outgoing mobile port broadcast types of traffic and do not classify incoming traf-
fic. In addition, multiple VLANs can have the same port rule defined. The advantage to this is that broad-
cast traffic from multiple VLANs is forwarded out one physical mobile port. When a mobile port is
specified in a port rule, however, its incoming traffic is still classified for VLAN assignment in the same
manner as all other mobile port traffic.
To define a port rule, enter vlan followed by an existing VLAN ID then port followed by a mobile
slot/port designation. For example, the following command creates a port rule for VLAN 755:
-> vlan 755 port 2/3
In this example, all traffic on VLAN 755 is flooded out mobile port 2 on slot 3.
Note that it is possible to define a port rule for a non-mobile (fixed, untagged) port, however, the rule is
not active until mobility is enabled on the port.
Use the no form of the
