Vlan Issue || Cisco Switch 4507

Hi All,

 

Today, i came across an issue according to which i found the interfaces on cisco switch 4507 were in different access vlan and were not under the business vlan which was configured and was working from past few months. Checked the logs but didnot found anything as such, not sure how come the access vlan got changed automatically, this issue was not for 2-3 interfaces , was however found for 150 ports approx.
Can anyone help me, if they have come across such issue, what can be done to figure it out. OR is it a bug or switch malfunction. 

Current IOS version : cat4500e-universalk9.SPA.03.04.06.SG.151-2.SG6.bin

Switch Uptime : more than 2 years

It was almost certainly done by a human.  Most likely, an accident.  Switches don't change their VLANs.

 

If their is a management platform or SNMP write is enabled then it could have done it as well.

 

if vstack has now been disabled it could also have been done via that.

Thanks Philip, but i just fetched the logs but do not see anyone's ID who made the change. there is no vstack it's a chassis. For SNMP it is RO not RW.

Post the first two lines to the command "sh run".

Post the complete command to the command "sh vstack config".
