Figure B.2: Ports Used with a KVM Switch Proxy Server Connection (KVM)
If the user wishes to establish a session with another port on the KVM switch, the same process
is used.
For debugging purposes, connection details may be seen by using the console port to place the
KVM switch into Debug mode.
Serial console appliance ports
Like a KVM switch, a serial console appliance may use a non-proxied or a proxied connection.
Serial console 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.
