Telneting to a Switch 65

4 Launch Telnet on your PC, with the IP address of the VLAN interface of the switch

as the parameter, as shown in

Figure 14.

5 Enter the password when the Telnet window displays "Login authentication" and

prompts for login password. The CLI prompt (such as <SW7750>) appears if the

password is correct. If all VTY user interfaces of the switch are in use, you will fail

to establish the connection and receive the message that says "All user interfaces

are used, please try later!". The Switch 7750 Family can accommodate up to five

Telnet connections at same time.

6 After successfully Telneting to a switch, you can configure the switch or display the

information about the switch by executing corresponding commands. You can

also type ? at any time for help. For configuration commands, refer to the related

modules in the command manual.

A Telnet connection is terminated if you delete or modify the IP address of the

VLAN interface in the Telnet session.

By default, commands of level 0 are available to Telnet users authenticated by

password. Refer to the Command Hierarchy/Command View section in chapter 1

for information about command hierarchy.

Telneting to another

Switch from the Current

Switch

You can Telnet to another switch from the current switch. In this case, the current

switch operates as the client, and the other operates as the server. If the

interconnected Ethernet ports of the two switches are in the same LAN segment,

make sure the IP addresses of the two management VLAN interfaces to which the

two Ethernet ports belong to are of the same network segment, or the route

between the two VLAN interfaces is available.
