Z After the changes are completed for each section, click OK to
register the changes.
Note that if the IP address is changed, the
http session has to be restarted with the new IP
address.
5.2.4 Using Telnet
The telnet client is enabled on the ML2400. The ML2400 supports five simultaneous
sessions on a switch: four telnet sessions and one console session. This allows many users
to view, discuss, or edit changes to the ML2400. This is also useful when two remote users
want to view the switch settings. The telnet client can be disabled through the command
line interface by using the
telnet disable command with the following syntax:
telnet <enable|disable>
Telnet can also be disabled for specific users with the
useraccess command. Refer to
User Management on page 1–14 for details.
Multiple telnet sessions started from the CLI interface or the command line are serviced by
the ML2400 in a round-robin fashion (that is, one session after another). If one telnet
session started from an ML2400 is downloading a file, the other windows will not be
serviced until the file transfer is completed.
The following example changes the telnet access. In this case, the enable command was
repeated without any effect to the switch.
ML2400# configure access
ML2400(access)##
telnet enable
Access to Telnet already enabled
ML2400(access)## exit
ML2400#
The show console command can show the status of the telnet client as well as other
console parameters. The following example reviews the console parameters with the
show
console
command. Note that telnet is enabled.
ML2400# show console
