Defining VLAN Rules

Defining DHCP Generic Rules

DHCP generic rules capture all DHCP traffic that does not match an existing DHCP MAC or DHCP port
rule. If none of these other rules exist, then all DHCP frames are captured regardless of the port they came
in on or the frame's source MAC address. Only one rule of this type is allowed per switch.
To define a DHCP generic rule, enter vlan followed by an existing VLAN ID then dhcp generic. For
example,
-> vlan 255 dhcp generic
Use the no form of the
-> vlan 255 no dhcp generic

Defining Binding Rules

Binding rules require mobile port traffic to match all rule criteria. The criteria consists of one of three
combinations, each of which is a specific binding rule type:
1
The device must attach to a specific switch port and use a specific MAC address and use a specific IP
network address (MAC-port-IP address binding rule).
2
The device must use a specific port and a specific source MAC address (MAC-port binding rule).
3
The device must attach to a specific switch port and use a specific protocol (port-protocol binding
rule).
If frames do not contain matching criteria, they are compared against other existing VLAN rules of lower
precedence. However, if a frame violates criteria of any one binding rule, it is discarded. Refer to
standing VLAN Rule Precedence" on page 7-8
Note that MAC-port-IP and MAC-port binding rules are also supported on Authenticated VLANs
(AVLANs). See Chapter 18, "Configuring Authenticated VLANs,"
The following subsections provide information about how to define each of the binding rule types.
