Figure B.2: Ports Used with a DS1800 or DSR Switch Proxy Server Connection (KVM)
If the user wishes to establish a session with another port on the DS1800 digital switch or DSR
switch, the same process is used.
For debugging purposes, connection details may be seen by using the console port to place the
DS1800 digital switch or DSR switch into Debug mode.
CPS and CCM appliance ports
Like a DS1800 digital switch or DSR switch, a CPS or CCM appliance may use a non-proxied or a
proxied connection. CPS and CCM appliances use a Secure Shell Protocol (SSH).
The client contacts the server, which checks the permissions of the target device. If the logged in
user has permissions to establish sessions to the selected target device, the server will establish a
connection to the appliance using TCP/IP port 3871 to authorize the session.
In a non-proxied SSH connection, the client communicates directly with the appliance using port
22. Figure B.3 illustrates the ports used with a non-proxied CPS/CCM appliance connection.
