Users Guide

The following restrictions apply when enabling the DHCP or PPPoE client on the controller:
l You can enable the DHCP/PPPoE client multiple uplink VLAN interfaces (up to four) on the controller; these
VLANs cannot be VLAN 1.
l Only one port in the VLAN can be connected to the modem or uplink switch.
l At least one interface in the VLAN must be in the up state before the DHCP/PPPoE client requests an IP
address from the server.
Enabling the DHCP Client
The DHCP server assigns an IP address for a specified amount of time called a lease. The controller
automatically renews the lease before it expires. When you shut down the VLAN, the DHCP lease is released.
In the WebUI
1. Navigate to the Configuration > Network > IP > IP Interfaces page.
2. Click Edit for a previously-created VLAN.
3. Select Obtain an IP address from DHCP.
4. Enter a priority value for the VLAN ID in the Uplink Priority field. All wired uplink interfaces have the same
priority by default. If you want to use an active-standby topology, then prioritize each uplink interfaces by
entering a different priority value (1– 4) for each uplink interface.

5. Click Apply.
In the CLI
In this example, the DHCP client has the client ID name myclient, and the interface VLAN 62 has an uplink
priority of 2:
(host)(config) #interface vlan 62
(host)(config) #uplink wired vlan 62 priority 2
(host)(config) #interface vlan 62 ip address dhcp-client client-id myclient
