I am trying to connect an OpenGear ACM5004-GV to my desk switch (WS-C3560CX-12PC-S) on Gi0/8.
I took the Opengear from our lab down the hall where it was connected to the LAB-Switch (WS-C3560CX-8PC-S) and given an IP 10.220.38.7 and where it was working properly.
However when I plug it into my DESK switch (same port config as LAB-Switch) the interface shows up/up but the mac address (0013.c600.e294) of the OpenGear does not show up. Furthermore I see no incoming packets from the device.
I have tried new cables / ports, as well as statically adding the mac address. I manually set the speed and duplex on my switch as the port was cycling between up and down initially. Both LAB and DESK Switches have identical trunk port uplinks to the same distribution switch. I am running out of ideas (or possibly missing something simple)
Let me know what other information I can provide. Thanks,
