Hello all,
We have an interesting issue that has just cropped up on our EX4200 switch stack at a school we manage. Every few days, the DHCP helper service (DHCP service) will fail and stop forwarding packets to the DHCP servers. This has worked for nearly 2 years, but all of a sudden, all DHCP stops after a few days. We can restart the DHCP service on the stack and it comes back and works for a while.
Any ideas out there on where to look? We did add 2 IP cameras to the network (in their own subnet) which coincides with the problem cropping up, but I can't image what 2 IP cameras could do to cause this, while we have hundreds of Chromebooks, PC's and student devices connecting during the school year without issue. We're in summer session which means that besides the cameras, and the wireless AP's, there are only about a dozen devices running, so load should be minimal.
From the attached logs, you can see that the switch runs fine until the errors appear and then no more DHCP...
Thanks!
