we have an SRW248G4 that we are running out of the box (no VLAN's defined). There are machines on several subnets connected to it. This works without any problems.
We have an SR520 configured to be attached to the SRW248G4; it has the 192.168.80.1 ip address.
When we connect it to the switch the entire switch locks down. It appears as though the switch suddenly wants to only talk VLANs on the 192.168.80.x subnet.
If we connect the SR520 to an old cheapo switch, and hook that up to the newer switch we have no problems.
Is there an easy way to change the config in the SR520 so it no longer meddles with the SRW248G4 ?
I am attaching the SR520 configuration.
