i had a vtp problem yesterday after an engineer connected a catalyst switch with higher revision number to my LAN; this caused an overwrite of the vlan info on the vtp server (6509); i recreated the vlan database on the server after disconnecting the rogue switch.
in my LAN, i have certain floors that have a 2950 and a 3550 in cascaded mode, the 3550s being connected to my core using G0/1 and to the 2950 using G0/2, with the mgmt vlan of all switches being 172.16.99.x.
Following this incident, my LMS server (.99.230) is able to reach only the 3550 switches, but not the 2950s. even from the 3550, i am unable to reach the directly connected 2950s, knowing that the trunk configs between the 2950s and 3550s are fine (has not been modified following incident).
any ideas please?
