OS2 on IOS based switches vs CATOS switches

Unanswered Question
May 10th, 2007

I have one OS2 server and 3 OS2 w/s directly connected to a single switch. The devices can communicate via layer 2 on a 1900 switch as well as a 5500 switch. However I am trying to connect them to a 3560 or a 3745. On the IOS based switches they do not communicate locally. There is no IP whatsoever, and they are all on the same VLAN. Any idea on what causes this?

I have this problem too.

Please make sure that the switch ports are configured as switch ports "switchport" not layer 3 ports.

What is the ports status, make sure that they are configured in the same VLAN and that the VLAN is configured on the switch, and review the speed/duplex config.

Already done. Same vlan, same port/duplex. Ports how as connected, however the devices cannot communicate via layer 2. thanks for the responses.
