I am trying to locate the IP address of a managed hirschmann switch in a small network set up in a spare room for the sake of learning about them as they are used at work. The switch in question [1of7] is acting like an unmanaged switch with no trace of any IP address - How do I find its IP address?
To eliminate the other switches that I have addresses into a new range of IPs, I linked the switch between a laptop and the gateway router, traffic passes through [I'm writing this question through the damm thing] I ran tracert and only the gateway router comes up. It passes through traffic on all ports but no register of it on wireshark that I can see. As well as wireshark, I tried angry IP, advanced IP, HIdiscovery, industrial HI Vision and found the addresses of 6 out of the 7 switches but can not get anything out of the 7th switch.
The switches were all Ebay purchases some new some 2nd hand unfortunately the seller didn't reset to factory settings with this one.
All the switches have a RJ11 v.24 serial port for management, I have spent the last few days making up serial cables trying different pin outs as the Hirschmann cable is 6 weeks away from Germany. I believe it is the same as the Schneider cable which has a description of pin out there website. I am also using a USB to serial converter which opens up com port 6. On one of the known switchs that I log in through webinterface it has all the telnet/ssh/bootP/v24 enabled but I can not open a telnet session with the switch. Mainly because I have little idea what I am doing, so if the answer to the question is use a serial cable, please be specific!
