Question

6.2 and 3rd Party GBIC

Has anyone tried 3rd party GBICs with 6.2.x?  We lost functionality when we upgraded to 6.2.x OS on the switch.  We reverted and they worked again.

 

Thx

    Which firmware version did you downgrade to? My GBICS are also not working in 6.2.1.

    We used a switch with 5.6.x for testing.  Then tried upgrading to 6.0.x and then downgraded again to verify they started working. Support has simply been talking around the problem with the standard "unsupported" line.  I've been working through my sales team to try to get an answer.  I purchased a ton of new GBICs and they are all useless if we upgrade.

    I found a solution to my problem which was connecting a standalone FW-124E to a Cisco 3750X via fiber. It appears in 6.2 there is an issue with the trunking. I removed the trunk setup on the FortiSwitch port in which I installed the GBIC, and just added all VLANs to the Allowed VLANs. Funny thing, the trunking worked when connecting the two switches by RJ45 ports.
