DHCPv6 Client

Overview

An ICX Layer 3 device can be set up as a Dynamic Host Configuration Protocol for IPv6 (DHCPv6) client to automatically receive an Internet Protocol version 6 (IPv6) address and other essential network configuration details from a DHCPv6 server.

These details include:

  • IPv6 Address: The unique address assigned to the ICX device.
  • Domain Name Server (DNS): The server that translates domain names into IP addresses.
  • Domain Search List: A list of domains to search when resolving hostnames.
  • Boot File Uniform Resource Locator (URL): The URL for the boot file needed during the startup process.
  • Control and Provisioning of Wireless Access Points (CAPWAP) Access Controllers: Controllers that manage wireless access points.

Requirements

DHCPv6 Client is not supported for RUCKUS ICX 7150 devices.

Considerations

This feature has the following considerations pertaining to feature enablement or usage:

  • The DHCPv6 client and DHCPv6 server cannot coexist.
  • Stacking ports, tunnel ports, and loopback ports are not supported.
  • Once an interface has been assigned an IPv6 address, whether through static configuration or dynamically via DHCPv6, the client no longer attempts to acquire IPv6 addresses on any other interfaces.
  • DHCPv6 stateful clients or DHCPv6 stateless clients can be configured.
  • After a stack switchover, the dynamic IP is relearned. Upon reboot or switchover, the DHCPv6 client's lease time is determined by the DHCPv6 server's response. If the server provides the remaining lease time, the client adopts this as its valid lifetime.
  • The DHCPv6 client supports a maximum lease time of 2,572,727,000 seconds.

Best Practices

Verify that the DHCPv6 client and server are compatible and correctly configured to communicate.

Prerequisites

IPv6 must be enabled on the device interface. Refer to the ipv6 enable command in the RUCKUS FastIron Command Reference for more information.
