Hi all, I've got two switches separated by about 7 miles of fiber and an Internet link at each site. I need a certain number of VLANs to extend between the sites for HA purposes. VLANs: tagged 243, 923-925, 927, 1000, untagged 4040 All of these VLANs span the trunk no problem except for 927. When I apply 927 the distant switch drops. When I remove 927, it comes back. Spantree is applied and enabled at the HA site, but not the main site. Where do I need to look to solve this problem?
