N2048 6.7.1 firmware upgrade InterVLAN routing broken
I had a switch stack recently upgraded to 6.7.1.22(from memory) and the interVLAN routing between VLAN1 and all other VLAN's isn't working. This switch was already programmed when I inherited it. They have servers on VLAN1...I never use VLAN1 for anything...so I'm trying to confirm if this new behavior is by design or possibly an issue with the firmware upgrade.
Thanks,
Roland

Hello Roland,
The upgrade should not break your routing.
What OS version were you on before the update?
Did you make a copy of running-configuration before the update?
Have you compared it to the current running-config?
Did you get the "Upgrading Dell EMC Networking N2000 Series Switches to 6.7.1.22 Firmware" from the https://dell.to/3QYS2Zd file?
You could test roll it back before the update, you should be able to isolate the issue as the FW or the configuration problem.

Thanks for the response Charles...and I agree with what you're saying...but VLAN1 will not route to the other VLANs...have compared the config from before the upgrade to after the upgrade...identical...it makes no sense whatsoever.
