38CHAPTER 1: USING SYSTEM ACCESS COMMANDS

Parameter

text: Enter the host name of the Switch. The host name must be no more than 30 characters long. The default is 4500.

Description

Use the sysname command to configure the host name of the Switch. Use the undo sysname command to restore the host name to the default of 4500.

Changing the hostname of the Ethernet switch will affect the prompt of command line interface. For example, if the hostname of the Ethernet switch is MyHost, the prompt in user view will be <MyHost>.

Example

To configure the hostname of the Switch to 3Com, enter the following:

<4500>system-view

System View: return to User View with Ctrl+Z.

[4500]sysname 3Com

[3Com]

system-view Syntax

system-view

View

User view

Parameter

None

Description

Enter system-viewto enter the system view from the user view.

Related commands: quit, return.

Example

To enter system view from user view, enter the following:

<4500>system-view

System view: return to User View with Ctrl+Z.

[4500]

telnet Syntax

telnet { hostname ip_address } [ service_port ]

View

User view

Parameter

hostname: Enter the host name of the remote Switch. It is configured using the ip host command.
