Command Usage

When using a bit mask to filter displayed MAC addresses, a 1 means "care"
and a 0 means "don't care". For example, a MAC of 00-00-01-02-03-04 and
mask FF-FF-FF-00-00-00 would result in all MACs in the range
00-00-01-00-00-00 to 00-00-01-FF-FF-FF to be displayed. All other MACs
would be filtered out.

Example

Web Authentication

Web authentication allows stations to authenticate and access the network in
situations where 802.1X or Network Access authentication are infeasible or
impractical. The web authentication feature allows unauthenticated hosts to request
and receive a DHCP assigned IP address and perform DNS queries. All other traffic,
except for http protocol traffic, is blocked. The switch intercepts http protocol traffic
and redirects it to a switch-generated webpage that facilitates username and
password authentication via RADIUS. Once authentication is successful, the web
browser is forwarded on to the originally requested web page. Successful
authentication is valid for all hosts connected to the port.

Notes: 1.

MAC authentication, web authentication, 802.1X, and port security cannot be
configured together on the same port. Only one security mechanism can be
applied.

2.

RADIUS authentication must be activated and configured properly for the
web authentication feature to work properly. (See “Configuring Local/Remote
Logon Authentication” on page 3-53)

3.

Web authentication cannot be configured on trunk ports.
