Usage Scenario

When a device serves as Telnet server, you can configure the ACL on the device to control the login of the clients to the device.

You can control client access based on the source address using a basic ACL or based on the source and destination addresses using an advanced ACL.
TELNETS only supports ACL matching based on the following parameters: source IP address, destination IP address, source port number, destination port number, and VPN.

Precautions

If no rule is configured, the incoming and outgoing calls are not restricted after the command telnet server acl is run.

The command telnet server acl takes effect for ipv4 function.
