# Using the Telnet Client

The system has an embedded Telnet client that enables you to connect to remote systems. You can configure a Telnet daemon to listen in virtual routers other than the default virtual router. You must be in the context of the desired virtual router to issue the command.

telnet

- Use to open a Telnet connection to a remote system.
- Specify the IP address or name of the remote host.
- You can specify a VRF context in which the request takes place.
- Depending on how the remote system accepts Telnet requests, you can specify a port number or port name through which the system will connect to the remote host. In the Transmission Control Protocol (TCP), ports define the ends of logical connections that carry communications. In most cases, you can accept the default, port number 23, the Telnet port. For more information about port numbers and associated processes, see www.iana.org.
- You can force Telnet to use the IP address of an interface that you specify as its source address.
- Example
  host1#telnet 192.168.35.13 fastEthernet 0
- There is no no version.
- See telnet.

telnet listen

- Use to create a Telnet daemon to listen in a virtual router.
- Example
  host1(config)#virtual-router 3 host1:3(config)#telnet listen port 3223
- Use the no version of the command to delete the daemon.
- See telnet listen.
