To test ports 10 through 16 on the CM4116 you need to type loopback -e eth0 /dev/port1.The screen will show 9 columns for serial loopback and one for Ethernet: If you are trying to capture traffic from a machine to itself, that traffic will not be sent over a real network interface, even if its being sent to an address on one of the machines network adapters. To invoke the inbuilt loopback diagnostics type in loopback -e eth0 /dev/port0 then press 'return'. The following will explain capturing on loopback interfaces a bit.Install the ELB on the Ethernet RJ45 socket and an SLB plug onto each serial RJ-45 sockets.You should now see the command line prompt which is a hash (#) Enter username 'root' and password 'default'. The console server will request a username and password. Log on to the console server by pressing 'return' a few times.If you are using "HyperTerminal" or a similar program running on a Windows PC as the terminal device, then the cable is made up from a Cat5 UTP (440016) cable and two DB-9 to RJ-45 adapters (319001) Plug a serial cable between the console server local DB-9 port and terminal device.Power up the console server and configure the serial connection of the "terminal" device/program you are using to 9600bps, 8 data bits, no parity and one stop bit.custom made RJ-45 Ethernet loopback plug (refer the ELB section at end of this faq).custom made R-45 serial loopback plugs (the SLB section at end of this faq shows the SLB required for a console server with Opengear classic pinout).To undertake these tests you'll need to have at hand: This test enables you to test the console server serial ports and your serial cabling. Check wall to switch connections easily without a cable. Easily check for broken or shorted wires. The Networx® RJ45 Loop back tester will negate the necessity to carry a bulky network hub around. The Loopback Test also undertakes an Ethernet loopback that senses the data transmitted is received properly. These Loop back testers will make the life of a network administrator really easy. The loopback program senses that data sent is received properly and that signals set and received properly. ![]() When undertaking a Loopback Test, each of the serial ports loop data transmitted to data received, RTS to CTS, and DTR to DSR + DCD. ![]() For example the Serial Ports panel will then show you the status of each serial port.Īlternately you can get this serail port status information from the command line by typing pmshell –signals –l port1 Hardware loopback testing the portsĮach console server has Loopback Test facilities built in. You can verify that devices are attached correctly to ports by navigating to the web interface and selecting Status: Statistics.
