88.37 Remote Management
Use this screen to specify a group of one or more “trusted computers” from which an administrator may
use a service to manage the Switch.
Click SECURITY > Access Control > Remote Management to view the screen as shown next.
Figure 590 SECURITY > Access Control > Remote Management
Service Port For Telnet, SSH, FTP, HTTP or HTTPS services, you may change the default service port by typing
the new port number in the
Service Port field. If you change the default port number then you
will have to let people (who wish to use the service) know the new port number for that
service.
Timeout Enter how many minutes (from 1 to 255) a management session can be left idle before the
session times out. After it times out you have to log in with your password again. Very long idle
timeouts may have security risks.
Login Timeout The Telnet or SSH server do not allow multiple user logins at the same time. Enter how many
seconds (from 30 to 300 seconds) a login session times out. After it times out you have to start
the login session again. Very long login session timeouts may have security risks.
For example, if User A attempts to connect to the Switch (through SSH), but during the login
stage, do not enter the user name and/or password, User B cannot connect to the Switch
(through SSH) before the
Login Timeout for User A expires (default 150 seconds).
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
