I migrated a set of Cisco Catalyst switches (2960, 3560, 3750) in IOS 15.0(2).SE of VTP v2 v3 for the VLAN ID support > 1005. I haven't found of problem during this migration period.
Since then, it happens that some Cisco 2960 (IOS c2960-lanbasek9-mz.150-2.SE6) lose their vlans (there is no more active than 1 vlans and 1002-1005). The solution I found is to return temporarily VTP v2 then go v3, this solves the problem but doesn't resolve it permanently.
Have you noticed the same problem ?
Since the c2960-lanbasek9-mz.150-2.SE6, Cisco released a SE9 but it is impossible to recover the release notes to see if this version (or one of preceding) correct or talk about this problem. Someone there a concept or is it that I can download it ?
Thank's in advance for your replies.
Thank's for your reply.
Since the Cisco Feature Navigator, the CAT2960 LAN BASE tolerates the VTP v3 therefore the extended range vlans. Do you have information or URL would argue otherwise ?
