Defining Dhcp Mac Address Rules - Alcatel-Lucent OmniSwitch 6850-48 Network Configuration Manual

Defining VLAN Rules
•
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
"Configuring Authenticated VLANs,"
Refer to the following sections (listed in the order of rule precedence) for instructions on how to define
each type of VLAN rule:
Rule
DHCP MAC Address
DHCP MAC Range
DHCP Port
DHCP Generic
MAC-Port-IP Address Binding
MAC-Port Binding
Port-Protocol Binding
MAC Address
MAC Address Range
Network Address
Protocol
Port

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

Defining DHCP MAC Address Rules

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