Re: 3.9.15.8011 blocks DHCP

Are there other DHCP events (beside debug dhcpsnooping packet) that I can monitor?

Re: 3.9.15.8011 blocks DHCP

I'm also still seeing the same behaviour on my switches:

FW: 4.0.10.9653

Controller: 5.9.29

DHCP Server: Windows 2012 R2

 

Steps to reproduce:

Remove DHCP snoop disable from my site config file and reprovision the switches. DHCP stops working from other VLANS (sorry theres a lot of stuff going on in the logs and I wasnt sure where to start and where to stop....):

As soon as I disable snooping again in my site config and reprovision, things start working again.

 

Is there any other info that I can give to help?
