Configuring The Registration Server Url; Unconfiguring A Mac-Auth Registration Server; Operating Notes For Http Redirect - HP E3800-24G-PoE+-2SFP+ Access Security Manual

Web and MAC Authentication
Configuring MAC Authentication on the Switch
4-64
Using the CLI. To reauthenticate a client using the CLI, use this command:
HP Switch(config)# aaa port-access mac-based <single-
port>
The keyword mac-addr specifies single client reauthentication. If the
reauthenticate parameter is entered without the mac-addr keyword and MAC
address, the command is executed as port reauthentication—all clients on a
port are reauthenticated.

Configuring the Registration Server URL

To configure the registration server URL, the command is:
HP Switch(config)# aaa port-access mac-based
For example:
HP Switch(config)# aaa port-access mac-based

Unconfiguring a MAC-Auth Registration Server

Each configured registration server's URL must be removed by specifying it
exactly, for example:
HP Switch(config)# no aaa port-access mac-based

Operating Notes for HTTP Redirect

■ If the configured URL contains a domain name (as opposed to an IP
address) the switch's DNS resolver must be configured:
HP Switch(config)# ip dns server-address priority
1 <ipv4-address>
■ The NAT does an IP route lookup before it sends the packet to the
destination registration server. A VLAN must have been configured
that allows the switch to access the registration server.
■ The initial page, redirect server, and filter path configuration will be
per-switch.
