Dhcp Proxy Operation, IP Address Assignment | HP NetRider specification

Learning IP Information From a DHCP Server

DHCP Proxy Operation

The access server can act as a DHCP proxy to provide IP address assignment for most remote clients.

IP Address Assignment

When you enable DHCP, the access server sends requests for IP addresses to a DHCP server on behalf of the remote client if:

∙You do not configure an IP address on the ports configured for remote access.

∙You do not specify an IP address using RADIUS authentication.

∙The remote client is not configured with an IP address for its PPP session.

When the access server receives the IP address from the DHCP server, it assigns the address to the remote client.

The following occurs when the access server uses DHCP to assign IP addresses to remote clients:
