Dear Team
I have an access switch (C2960S-48FPS-L) which is running on version (universalk9-mz.122-55.SE5).
This switch was running on VTP client mode and connected to distribution switch running on VTP client mode and vtp version 3, due to power failure the switch got reloaded and after reload it came to VTP server mode and all the vlans were deleted, but the SVI of the vlan and all other config was still there.
I noticesd the same behavior with other switches of model (C2960S-48FPS-L & WS-C3560X-48PF-L) running on the following IOS
1) 12.2(55)SE'X' (here X means, it could be SE3,SE4,SE5etc)
2) 12.2)58SE'X' (here X means, it could be SE3,SE4, SE5 etc)
3) 15.0(2)SE (here X means, it could be SE3,SE4, SE5 etc)
I also noticed the following error during switch reload.
"%SW_VLAN-4-BAD_VLAN_CONFIGURATION_FILE: VLAN configuration file contained incorrect verification word:[hex]."
The issue is intermittent means the same switch will not have issue sometime after reload but sometime it will have this issue.
Anybody have any idea, is this bug causing this issue or something else.
Appreciate your response.
