I have a customer who has three Intellinet 523554 switches in the core and misc. switches at the edge, including a PowerConnect 2716. The firewall is a Sonicwall, which is plugged into one of the Intellinet switches, and there are three new SonicPoints that are plugged into the PowerConnect switch. To the best of my understanding, even though X0 (LAN) and X2 (WLAN) are bridged at the SonicWall, I need to keep these networks separate. If I plug both into VLAN 1, the network crashes (I presume because of a broadcast storm). On all switches, I've created VLAN 2, left VLAN 1 untagged, and configured the appropriate access and trunk ports as necessary. Both types of switches use web-based configuration, and there simply aren't many parameters to adjust. VLAN 1 traffic passes OK across the trunk, but VLAN 2 does not. I'm not familiar with configuring the Intellinet switches, so I sent an email into their support. Unfortunately, to them trunking is what the rest of the world calls link aggregation, so I don't have any help from them yet. I feel relatively confident the configuration is as good as it can get.
Has anyone else tried this and been successful? Any thought? The PowerConnect switch is running 1.0.1.07 firmware. Thanks
