I have a situation where a client has upgraded their network equipment in their building from 3Com managed switches and a 3Com 5012 router. Previously, the managed switches were used to create several VLANs to segment the office suites in the building. This configuration worked without issue.
The switch equipment was upgraded to Dell PowerConnect as follows (1) 3524-master and (2) 3548's-slaves to allow for a new PoE VoIP phone system. The router was retained to allow for internet traffic. However at this point i am not sure if the 5012 is compatible with the Dell's or there is a configuration error as the PCs on the VLAN network cannot sustain a consistent connection to the internet or in some cases not at all. Has anyone had a similar situation occur and have a suggestion. PS, I'm not a real VLAN expert...!!! Also attached is the VLAN setup on the switches.
