how to preserve priority tag in Cisco 2960?

I have some device attached to Cisco 2960. These device send GOOSE message to each other. GOOSE message conveys a 802.1Q tag to indicates its priority. The VID in GOOSE message is default 0.

If the ports are configured in access mode, it drops all the tagged packet. If I configured the port in trunk mode, it will strip the

802.1Q tag. I also tried to configure the port to be voice vlan, it also removes the 802.1Q tag.

I just want to find a way to preserve the priority tag during switching. Can somebody help ?
