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.

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 web page that facilitates user
