Redirecting Traffic to the Correct Port

B.

The command that should be used to redirect traffic to the correct port when configuring web authentication using non-standard ports on a Cisco switch is option B, "ip http port <port number>".

Explanation: By default, the HTTP server on a Cisco switch listens on port 80. However, in some cases, a network administrator may need to use a different port for web authentication, for example, to avoid conflicts with other applications or to improve security. The "ip http port <port number>" command can be used to configure the switch to listen on a non-standard HTTP port.

For example, if the network administrator wants to use port 8080 for web authentication, the command to be used is:

scssCopy code
Switch(config)# ip http port 8080 

This command tells the switch to listen on port 8080 for HTTP traffic.

Note that this command only configures the switch to listen on a non-standard port for web authentication. To actually redirect traffic to the correct port, additional configuration may be necessary, such as configuring a Layer 3 device to perform NAT or port forwarding. However, this command is the first step in the process of configuring web authentication on a non-standard port.

Option A, "permit tcp any any eq <port number>", is not related to redirecting traffic to the correct port for web authentication. This command is used in an access control list (ACL) to permit TCP traffic on a specific port.

Option C, "aaa group server radius", is used to create a group of RADIUS servers that can be used for authentication and authorization on a Cisco switch. This command is not related to redirecting traffic to the correct port for web authentication.

Option D, "aaa group server radius proxy", is used to configure a Cisco switch to act as a proxy for RADIUS authentication requests. This command is not related to redirecting traffic to the correct port for web authentication.
