• Hostname
• Stack number of a member switch (1-16) if the switch is a commander in a
stack and stacking is enabled
For switches that have a separate out-of-band management port, the oobm parameter
specifies that the Telnet traffic will go out from the out-of-band management interface.
If this parameter is not specified, the Telnet traffic goes out from the data interface.
The oobm parameter is not available on switches that do not have a separate
out-of-band management port. See Appendix I, "Network Out-of-Band Management"
in this guide for more information on out-of-band management.
Note: If the console idle-timeout expires, any outbound Telnet or SSH sessions
that are open on the switch are terminated. (For information on console
idle-timeout, See “Reconfigure the console/serial link settings” (page 95).)
For example, if the host "Labswitch" is in the domain abc.com, you can enter the following command
and the destination is resolved to "Labswitch.abc.com".
HP Switch(config)# telnet Labswitch
You can also enter the full domain name in the command:
HP Switch(config)# telnet Labswitch.abc.com
You can use the show telnet command to display the resolved IP address.
Example 72 The show telnet command displaying resolved IP addresses
HP Switch(config)# show telnet

Making window size negotiation available for a telnet session
When a telnet connection is established with a switch, the switch always uses the default values
of 80 columns by 24 lines for the window dimensions. The window can be resized by either
dragging the corner of the window, or by executing the terminal length <x> width <y>
CLI command and then configuring the telnet client with those dimensions. The new window
dimensions are lost after that telnet session ends.
When the telnet connection is established with an HP switch, either the switch or the telnet client
needs to initiate the inquiry about the availability of NAWS. If NAWS is available, you can resize
the window by dragging the corner of the window to the desired size. The telnet software uses
NAWS to tell the switch what the new window dimensions are. If the switch supports the requested
window dimensions, it uses them for all future interactions. If the switch does not support those
