Have you guys seen a problem like this before? After a shutdown due to power outage, some vlans being trunked to an access layer switch would not pass traffic. Some vlans connected and allowed traffic, some did not. We had to disable and re-enable to trunk port on the distribution switch to get all of the vlan to pass traffic.
Aside from not passing traffic, the vlans, interfaces and trunking configs are normal. The only way you can tell that the vlan is not passing traffic is the loss of connection with the end devices (PCs, printers, etc..).
