relay-agent

Enables support for DHCP/DHCPv6 relay agent information (option 82 and DHCPv6-LDRA) feature on this WLAN. This option is disabled by default.

Supported in the following platforms:

Syntax

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

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.
