Parameters

relay-agent [dhcp-option82|dhcpv6-ldra]


relay-agent	Enables support for the following DHCP and DHCPv6 options: option 82 and Lightweight DHCPv6 Relay Agent (LDRA) respectively. When enabled, this feature allows the DHCP/DHCPv6 relay agent to insert the relay agent information option (option 82, LDRA) in client requests forwarded to the DHCP/DHCPv6 server. This information provides the following: circuit ID suboption – Provides the SNMP port interface index remote ID – Provides the controller‘s MAC address
dhcp-option82	Enables DHCP option 82. DHCP option 82 provides client physical attachment information. This option is disabled by default.
dhcpv6-ldra	Enables the DHCPv6 relay agent. The LDRA feature allows DHCPv6 messages to be transmitted on existing networks that do not currently support IPv6 or DHCPv6. This option is disabled by default.
