Usage Guidelines

Usage Scenario

To prevent a client from connecting to the Telnet server through an unauthorized physical interface, you can run the telnet server permit interface command to specify physical interfaces on the Telnet server to which the client can connect.

Precautions

  • By default, the client can connect to all the physical interfaces on the Telnet server. When you run this command to specify one physical interface on the Telnet server, the client cannot connect to the other physical interfaces on the Telnet server.
  • You can specify a maximum of five interfaces each time you run the telnet server permit interface command. The latest configuration overrides the previous one. For example, before you run the command, clients can connect to three physical interfaces GigabitEthernet 1/0/0, GigabitEthernet 2/0/0, and GigabitEthernet 3/0/0 on the Telnet server. After you run the command to specify the interface GigabitEthernet 1/0/0, clients can only connect to the interface GigabitEthernet 1/0/0.

Example

# Specify physical interfaces on the Telnet server to which clients can connect.
