Hi all,
We're scratching our head. Customer added a new building where we've installed four Netvanta 1550P switches. We pre-configured and deployed, and all are working like a champ except for admin via LAN (http, ssh, etc).
When these four switches are disconnected from the rest of the customer's network, all admin works exactly as expected. However, when we connect to the rest of customer's network, LAN admin simply stops working. Note that all OTHER network devices in this new building remain accessible via http, as do all other non-Adtran devices in their "old" buildings. Connection to "old" building is via fiber with yet another Adtran 1550P at far end. We cannot access that switch either when rest of network is connected. Firmware on all switches is 12.3.4. Serial admin functions fine at all times. We have addresses assigned to both VLANs, no joy accessing either with rest of network connected. Customer has a third-party company managing their core network, we haven't gone too far down that road as all other devices appear to be normally accessible - only the Netvanta switches are negatively affected. We have a fairly straight-forward config - all switches use essentially the same config, with different IP addresses:

I'd be thrilled if anyone can point out our boneheaded mistake. Thanks
