-WEB-SERVER DHCP IPADDRESS
auth-web-server dhcp ipaddress
Overview Use this command to assign an IP address and enable the DHCP service on the
Web-Authentication server for supplicants (client devices).
Use the no variant of this command to remove an IP address and disable the DHCP
service on the Web-Authentication server for supplicants.
Syntax
auth-web-server dhcp ipaddress <ip-address/prefix-length>
no auth-web-server dhcp ipaddress
Default No IP address for the Web-Authentication server is set by default.
Mode Global Configuration
Usage notes See the AAA and Port Authentication Feature Overview and Configuration Guide
for information about:
• using DHCP with web authentication, and
• restrictions regarding combinations of authentication enhancements
working together
You cannot use the IPv4 address assigned to the device’s interface as the
Web-Authentication server address.
Note that this Web Authentication virtual DHCP server is a limited implementation
of the DHCP protocol. Separation of IP addresses depends on allocating addresses
incrementally and a short lease time. In a situation where a supplicant remains
permanently connected but does not authenticate, there is a risk of re-allocation
of the same IP address once the server has rolled through the entire address range.
Examples To assign the IP address 10.0.0.1 to the Web-Authentication server, use the
following commands:
awplus# configure terminal
awplus(config)# auth-web-server dhcp ipaddress 10.0.0.1/8
To remove an IP address on the Web-Authentication server, use the following
commands:
awplus# configure terminal
awplus(config)# no auth-web-server dhcp ipaddress
Parameter Description
<ip-address/
prefix-length>
The IPv4 address and prefix length assigned for the DHCP
service on the Web-Authentication server for supplicants.
