I have a cisco catalyst 2924mxl-en, and a number of different non-managed, non-bridging 100baseFX-100baseTX media converters. I unfortunately do not have access to the switch or its configuration, and I was curious whether anybody knew if there was a way to manually set a port to 100mbit/full duplex, since the media converters do not support autonegotiation. Thanks!
Hi there, when you say you don't have access to the switch, I assume you mean physical access - therefore you can't establish a console connection. If this is the case you could telnet onto the switch and configure the port from there as follows:
set port speed 1/1 100
Where 1/1 is the module/port that the converter is patched into. The 100 represents the fact that you are fixing the speed at 100MB.
The command to set the same port as full duplex would be:
set port duplex 1/1 full
Although autonegotiation is an IEEE standard, it is always best practice to fix a port speed/duplex mode because I've seen no end of problems with differing devices trying to autonegotiate their settings.
Hi, I have seen this and dealt with it loads of times... what is at the remote end....
if it is a hub you can plug the hub in, plug the convertor into the hub then connect the fibre to the convertor at the other end and then plug it into the switch... this will give you a half duplex link...
you can use the mode button to fdup if the port is lit it will be full duplex mode. There is a simple method to backdoor the switch and re-setting it up which is on the 2900 website... the other option which I would advise everyone is dont buy convertors they are cheap and nasty...tx-fx bridges are the way to go cheers julian
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
