i have recently upgraded the IOS on this switch,

if i try to add a VLAN or configure SNMP on the switch it reboots and all old configuration will be lost,

below are the switch details,

This looks like the bug in the IOS

Try downgrading to the old IOS & then see.

If it works with old IOS ,definitely it is IOS bug,

Then try to use stable version of ADVIPSERVICEK9

HTH..rate if helpful..

Do a dir flash and see how much space you have left out of the total, if need be delete your old image out of flash or delete the new image and reload the old one and see what happens.

Switch#sh boot

BOOT path-list : flash1:c3750-ipservices-mz.122-25.SEB4/c3750-ipservices-mz


Config file : flash:

Isn't the empty config file name strange?

See show boot example at


How does your confreg look like?
