Cisco Trunking and Unifi Help

bobstertime · February 4, 2021, 6:46pm

Hey guys fighting an issue here. We have a trunk port connected to the AP and I’m trying to set different vLans per said. And for some reason not getting an ip address. The dhcp helper is set on every vLan on Cisco and still not working. I also can log into AP and ping them all. Lol on Ubiquity switching this process is super simple and this should be as well. Many thanks!

I am no Cisco expert by any means but did you announce the VLAN to the switch? I mean to you see something like

!
VLAN 140
name WLAN-Extern
!

in the running conifg? Maybe you have to switch a so called VTP mode to see the entries in the running config: vtp mode transparent

Thanks guys the trunk is announced on the AP port reviewed config with network engineer. I can get to any of the vlans on the trunk but can’t tag on AP successfully.

Do you have the Cisco config for the interfaces? Are you restricting VLANs on the trunk?
