Troubleshooting 6248

Hi all,

Replacing a HP L3 Switch with a Dell PC6248 and trying to get the configuration right. The HP switch had a lot less options since it was pretty darn cheap and sufficed for what we needed at that time.

My setup looks like this:

1/g1 - uplink xxx.xxx.1.160/24(vlan4) (xxx.xxx.1.164)
1/g2-21 - xxx.xxx.211.0/24 (vlan2) (xxx.xxx.211.1)
1/g22-47 - xxx.xxx.231.0/24 (xxx.xxx.231.1)
1/g48 - management vlan (vlan1)

The uplink is through a cisco switch managed by our ISP.

Testing routing between the VLANs works in testing - got a desktop set up with .231.100 and a laptop with .211.100 and they can run speed tests against eachother with max speed. The same goes for the .1.164 when i switch the laptop to it.

BUT when I set the laptop to .211.100 and then connect our uplink to 1/g1 I am no longer able to ping .211.1 or .1.164 or .231.1. But I am able to ping hosts on the internet and and our ISPs switch in the building .161.1.
As soon as I pull out the cable, Im then able to ping locally on the switch again.

Here is the running config:
