Controlling Web Users by Source IP Addresses
The 3Com Switch 4500G support Web-based remote management, which allows Web users to access
the switches using the HTTP protocol. By referencing access control lists (ACLs), you can control the
access of Web users to the switches.
Prerequisites
The control policies to be implemented on Web users are decided, including the source IP addresses to
be controlled and the control action, that is, whether to allow or deny the access.
