Example usage:
To configure the DHCP relay option 61:
DES-3528:admin# config dhcp_relay option_61 add mac_address 00-01-22-33-44-55 drop
Command: config dhcp_relay option_61 add mac_address 00-01-22-33-44-55 drop
Success.
DES-3528:admin#
This command is used to configure the DHCP relay option 61 state.
config dhcp_relay option_61 state [enable | disable]
This command decides whether DHCP relay will process the DHCP option 61 or not. When
enabled, if packets do not have option 61, then the relay servers cannot be determined
based on option 61. Because the priority of option 60 and option 61 is higher than per IPIF
configured servers, if the relay servers are determined based on option 60 or option 61, then
per IPIF configured servers will be ignored. If the relay servers are determined neither by
option 60 nor option 61, then per IPIF configured servers will be used to determine the relay
servers.
enable – Enables the fuction dhcp_relay use option_61 ruler to relay dhcp packet.
disable – Disables the fuction dhcp_relay use option_61 ruler to relay dhcp packet.
Only Administrator and Operator and Power-User-level users can issue this command.
This command is used to add a rule for dhcp_relay option_61.
config dhcp_relay option_61 add [mac_address <macaddr> | string <desc_long 255>]
[relay <ipaddr> | drop]
This command adds a rule to determine the relay server based on option 61.
The matched rule can be based on either the MAC address or a user-specified string. Only
one relay server can be specified for a MAC-address or a string.
Both option 60 and option 61 can assign particular DHCP relay sever, so they can altogether
determine which relay server will be selected.
mac_address – The client's client-ID which is the hardware address of client.
string – The client's client-ID,which is specified by administrator.
relay – Specify to relay the packet to a IP address.
drop – Specify to drop the packet.
Only Administrator and Operator and Power-User-level users can issue this command.
