I have had issues using auto-upgrade on 3750 switches. The 16M of flash is pretty low and auto-upgrade can fail if there is a bunch of stuff on flash that isn't image related. The latest IOS is a lot larger than the image shipped on most 3750 switches, so storage is a lot tighter than what some may have experienced in the past.
Another failure scenario I have run into is when you have one switch with a lower license level than the other switches in the stack (1 LANBase switch in a stack of IP Services). The switch will need the image for LAN Base, but all the other switches will have the image for IP Services, so the auto upgrade won't work. -----Original Message----- From: cisco-nsp [mailto:[email protected]] On Behalf Of Harry Hambi - Atos Sent: Friday, March 3, 2017 2:58 AM To: '[email protected]' <[email protected]> Subject: [c-nsp] 3750 Stack Auto Upgrade Hi Everyone, Has anyone one successfully upgraded stacks with the auto upgrade feature?. If a member of a stack failed it would be nice if when replacing the failed unit it would be automatically upgraded from the master. When I say upgraded I mean the IOS and the configuration, is this possible. Any advice appreciated.
