I have building A and building B. They are connected via fiber with 1 GB transition fiber transceivers on both ends. Currently building A has a stack of C3750-24-TS, building B has a couple SGE2010P switches in non-stack mode. Building B is on a vlan. Everything works great.
We setup wireless access points in building b. We want to share buildings A wireless controller and have the public/private traffic segmented. We need to have building B see a bunch of vlans.
We had a spare 3750 we deployed it to building B, and trunked the fiber ports. The trunk comes up. I can see all the vlans on both sides. I’m able to get DCHP at building B from building A, and ping networks and devices at building A. When I try to pull up a web page, or log in to workstation traffic halts to a standstill. DNS look ups appear to function normally.
Vlan1 = building A
Vlan68 = building B
Attached are the building B 3750 config
The fiber port configuration
Any help appreciated! There are no errors on either switch after trunking.
