Configuring bridges to support DHCP relay
This procedure describes how to configure bridges on the EtherXtend to
support DHCP relay. This procedure assumes the following configuration has
already been performed on the EtherXtend.
•
Downlink bridge to the host
•
Uplink bridge to network
•
IP interface on the EtherXtend with a route available to the DHCP server
To configure bridge support for DHCP relay:
1
Configure the packet-rule-record using the group number of the bridge
and add the record to either the bridgeIfIngressPacketRuleGroupIndex
interface or the bridgeIfEngressPacketRuleGroupIndex interface
depending on the type of bridge.
zSH> new packet-rule-record 1/1
packet-rule-record 1/1
Please provide the following: [q]uit.
packetRuleType: ---> { bridgeinsertoption82 }: bridgedhcprelay
packetRuleValue: --> {}: 1 [dhcp-server-subnet index]
packetRuleValue2: -> {}:
packetRuleValue3: -> {}:
packetRuleValue4: -> {}:
packetRuleValue5: -> {}:
....................
Save new record? [s]ave, [c]hange or [q]uit: s
Record saved
2
Verify that the bridge-interface-record contains correct bridge
IfConfigGroupIndex value. This value represents the bridge
configuration group index specified for the bridge-config-record.
zSH> get bridge-interface-record 1-1-4-0-eth/bridge
