Comtrol PortVision DX - Manual (Page 141)

Telnet SSH Sessions
There are two ways to access a Telnet/SSH session in PortVision DX:
•
Right-click the Comtrol Ethernet attached product in the Device List pane and click
Telnet/SSH Session.
•
Highlight the Comtrol Ethernet attached product in the Device List pane, click the
Manage menu and then Telnet/SSH Session.
You may need to use the Telnet/SSH Session option to upload firmware on DeviceMasters that
reside on the other side of several switches, a router, or wireless.
Note: You can use this option to access the RocketLinx managed switches CLI
(Command Line Interface).
DeviceMaster TCP and UDP Socket Ports
Following list is all of the logical TCP and UDP socket ports implemented in DeviceMaster.
Socket Port Number Description
22 SSH
23 Telnet
TCP Ports 22 (ssh) and 23 (telnet) are used for administrative and
diagnostic purposes and aren't required for normal use and are enabled
by default and Port 23 may be disabled.
80 HTTP
443 SSL or HTTPS
TCP Ports 80 (http) and 443 (https) are used by the web server for
administration and configuration and are enabled by default and cannot
be disabled.
102 RFC1006
TCP Port 102 is used for RFC1006 (ISO over TCP) serial port access.
Not used for normal NS-Link SocketServer access.
The RFC1006 server can be disabled by setting the server port number
to -1 and is enabled by default.
161 SNMP UDP
Port 161 is used by the SNMP agent if SNMP is enabled which is the
default.
4606
TCP Port 4606 is required if you want to use NS-Link or PortVision DX if
you want to update firmware without setting up a TFTP server and this
port cannot be disabled.
4607
TCP Port 4607 is only used for diagnostic purposes and is not required
for normal operation and this port cannot be disabled. If SocketServeris
to be used, then the user may enable usage of TCP or UDP ports for
access to the serial ports. These ports are not enabled by default and
are also user configurable to different values. Defaults for TCP would
begin at 8000 and for UDP would begin at 7000.
TCP 8000 - 8xxx
This user configurable port is incremented per serial port on the
DeviceMaster.
For example: A DeviceMaster 16-port would have Ports 8000 through
8015.
