Der all, I have a Catalyst 2948G which seems to keep PXE boot from working properly. This one Cat2948 is the only Layer 2 device between the DHCP/PXE boot server and the PXE client - both are directly connected and share a /24. PXE boot is not working at all, and DHCP is unbearably slow, for no apparent reason. Both PXE Server and Client(s) are various IBM xSeries using the onboard GBit interfaces. Now the fun stuff: when I put a second Layer 2 device between the Cat 2948 and the PXE client, it is magically working. Means: PXE Server -> Cat 2948 -> "some cheap Netgear Office switch" -> PXE Client == works. In fact, any additional Layer 2 device that appears between PXE Client and the Cat 2948 scares the problem away.
Anyone seen this before? Any hints where to start looking? The switch looks as follows: WS-C2948 Software, Version NmpSW: 8.4(11)GLX Copyright (c) 1995-2006 by Cisco Systems, Inc.
