Interface Access and System Information
Denying Interface Access by Terminating Remote Management Sessions
You can also execute a series of console commands and then save the
configuration and boot the switch. For example:
ProCurve(config)# console baud-rate speed-sense
Command will take effect after saving configuration and reboot
ProCurve(config)# console flow-control xon/xoff
Command will take effect after saving configuration and reboot
parameters.
ProCurve(config)# write memory
ProCurve(config)# reload
Save the
changes.
Boot the
switch.

Denying Interface Access by Terminating
Remote Management Sessions
The switch supports up to five management sessions. You can use show ip ssh
to list the current management sessions, and kill to terminate a currently
running remote session. (Kill does not terminate a Console session on the
serial port, either through a direct connection or via a modem. It does not
affect the console on the standby module.)
Syntax: kill [< session-number >]
For example, if you are using the switch’s serial port for a console session and
want to terminate a currently active Telnet session, you would do the
following:
