Also be informed that if you're mixing CBS350's with Catalyst switches and you're using multiple VLANs, you need to set the VTP mode on the Catalysts to either Transparent or Off. A symptom of not doing so is that when a device on a non-native VLAN on the CBS350 issues a DHCP request that must traverse a Catalyst to reach the DHCP server, the response from the DHCP server will not be delivered back to the client and will instead "die" inside the Catalyst switch.
