Example usage:
To configure the DHCP relay option 61 default:
This command is used to add a rule for dhcp_relay option_61.
config dhcp_relay option_61 add [mac_address <macaddr> |string <desc 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.
If the relay servers are determined based on option 60, and one relay server is
determined based on option 61, the final relay servers will be the union of these
two sets of the servers.
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-level users can issue this command.
This command is used to determine the default ruler for option 61.
config dhcp_relay option_61 default [relay <ipaddr>|drop]
This command is used to determine the rule to process those packets that have no
option 61 matching rules. The default default-rule is drop.
relay – Specifies to relay the packet that has no option 61 matching rules to an IP
address.
drop – Specifies to drop the packet that has no option 61 matching rules.
Only Administrator-level users can issue this command.
