The traffic tcpdump shows are: * directed TCP and UDP traffic * arp requests packets * 802.1d packets - spanning tree * UDP NBT broadcast packets (ports 137,138) * UDP rwhod broadcast packet (port 513) Arp is lower level then IP, right? It is sent to all ports of the switch, not to the IP broadcast address, right? 802.1d is also lower level then IP, right? Will 802.1d spanning tree be broken by this change? And yes, we have several switches on this one subnet. This network is a "test" network, and not a production network. So as long as the only problem will be communication between the old configured servers, and the new configured servers, this is acceptable. All of the systems need to be able to access the Internet, and systems within the old config need to be able to speak to other systems within the old config. Is there anything else I should check?
