Cisco CATALYST 2960 - Understanding Auto-Upgrade and Auto-Advise; When the software detects mismatched software and tries to upgrade the switch in version-mismatch mode, two software processes are involved: automatic upgrade and automatic advise.; The automatic upgrade (auto-upgrade) process includes an auto-copy process and an auto-extract process. By default, auto-upgrade is enabled (the boot auto-copy-sw global configuration command is enabled). You can disable auto-upgrade by using the no boot auto-copy-sw global configuration command on the master. You can check the status of auto-upgrade by using the show boot privileged EXEC command and by checking the Auto upgrade line in the display.; Auto-copy automatically copies the software image running on any member to the switch in version-mismatch mode to upgrade (auto-upgrade) it. Auto-copy occurs if auto-upgrade is enabled, if there is enough flash memory in the switch in version-mismatch mode, and if the software image running on the stack is suitable for the switch in version-mismatch mode.
