Function: Login on the remote host by Telnet

Parameter: <vrf-name> is the specific VRF name; <ip-addr> is the IP address of the

remote host, shown in dotted decimal notation; <ipv6-addr> is the IPv6 address of the

remote host; <hostname> is the name of the remote host, containing max 64 characters;

<port> is the port number, ranging between 0 and 65535.

Command Mode: Admin Mode.

Usage Guide: This command is used when the switch is applied as Telnet client, for

logging on remote host to configure. When a switch is applied as a Telnet client, it can only

establish one TCP connection with the remote host. To connect to another remote host,

the current TCP connection must be disconnected with a hotkey ―CTRL+ \‖. To telnet a

host name, mapping relationship between the host name and the IP/IPv6 address should

be previously configured. For required commands please refer to ip host and ipv6 host. In

case a host corresponds to both an IPv4 and an IPv6 addresses, the IPv6 should be

preferred when telneting this host name.

Example: The switch telnets to a remote host whose IP address is 20.1.1.1.

Switch#telnet 20.1.1.1 23

Connecting Host 20.1.1.1 Port 23...

Service port is 23

Connected to 20.1.1.1
