I have attached truncated configuration of the switch taken on the 23rd June. Kindly note the configuration of G1/0/1. Today under this interface I had only applied the switchport trunk allowed vlan remove 1607.
What happened next was all vlans of that port vanished and whatever L3 device we had over that port communication went down as VLANS were not accessible.
I am not sure what went wrong ..Later i found that it was allowing the vlan 1607 and i had to revert back the original plain trunk configuration.
