I have read through most of the posts here, and for some reason I still cannot get this DHCP snooping issue resolved. I had originally turned off Option 82 on all of the switches at the site, but after reading through @Peter Paluch's posts on it, I r...

Some of our IP phones are located in bedrooms and at night when the phone goes into power-save mode, the select button LED lights up. It is bright enough to light up the room and cause people to complain. Is there any way to disable this LED from ill...

I have just deployed a new 3850 with the integrated wireless controller and 2 2600i APs. Before joining the APs to the controller, I upgraded them to the latest LWAPP image. It appears that they were downgraded when joining the controller the first t...

That command is already on my DHCP server after having read through previous threads.

It's definitely still an issue somewhere. I temporarily disabled DHCP snooping on SW1 and the AP attached to SW2 picked up an IP address. I tried to get the AP on SW3 to pick up an IP and it would not. I tried disabling DHCP snooping on SW2 but there...

Even after adding that command it's not working. The output of the debug makes it look like the DHCP offer from the router is getting passed on from SW1 to SW2 (where this AP is plugged in directly) but the client doesn't get the IP assigned. Apr 1...

Yes, attached are the 3 sanitized configs for the switches and the log messages from the "debug ip dhcp snooping packet detail" command on SW1. I didn't see any output from SW2 or SW3 which were running the same debugs at the time.
