dhcpServerMacAddress
Module: PEA-BRIDGE-IPDSLAM
OID (symbolic): PEA-BRIDGE-IPDSLAM::dhcpServerMacAddress
OID (numeric): 1.3.6.1.4.1.193.72.300.30.1.3.1.115
Node type: OBJECT-TYPE
Type: MacAddress
Access: read-write
Description:
Use this parameter to convert the end-users DHCP messages from broadcast to unicast. This is very usefull when trying to minimise the amount of broadcast in a L2 network.
When the IP-DSLAM receives a DHCP Discover or a Request it will change the destination MAC address from the broadcast address to the configured DHCP Server Mac Address (This parameter).
- To enable the functionality add the MAC address of the DHCP server (To configure 00-80-03-04-05-06 add 0x00 0x80 0x03 0x04 0x05 0x06) - To disable the functionality add MAC address 00-00-00-00-00-00
Note: When using this function the end-user will no longer be able to select between different DHCP servers. This functionality is only valid if accessMethod is set to 'dhcp' or 'dhcpIpoa'.
Valid from: EDA 2.2 R3A
What is dhcpServerMacAddress?
This configuration parameter lets an IP-DSLAM device convert DHCP broadcast traffic into unicast frames destined to a specific MAC address (the DHCP server). By unicasting DHCP messages instead of broadcasting them, this feature reduces broadcast overhead in Layer 2 networks and forces all DHCP clients through a single designated server. DSL operators enable this when they want stricter DHCP control and lower multicast traffic.
