Basic Operation Guide 2013/06

Syntax:
telnet <ipv4-addr | ipv6-addr | hostname | switch-num> [oobm]
Initiates an outbound telnet session to another network device. The destination can
be specified as:
• IPv4 address
• IPv6 address
• 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. Refer to 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, refer to “Reconfigure the console/serial link settings” (page 98).)
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 76 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>
