Cisco Bug: CSCuj69384 - IOS Modify default behavior Express Setup to avoid unexpected invocation
Nov 29, 2019
- Cisco Catalyst 3750-X Series Switches
Known Affected Releases
Symptom:Express Setup is a feature that allows for quick configuration of basic features on the WS-C3750X and other IOS based switches. Express Setup is invoked through holding the Mode button for 2 seconds on an unconfigured switch or for 10 seconds on a previously configured switch. When this happens the switch configuration is deleted and the switch reboots and can be configured using Express Setup or via the CLI. Large anti-snag cable boots have the potential of coming into contact with the mode button resulting in the unexpected invocation of Express Setup. This request is for a change in the default behavior of Express Setup to avoid invocation when a switch is in production and invocation is undesirable. Conditions:The cable boot is making extended contact with the mode button resulting in Express Setup being invoked. When this happens the following messages will be seen on WS-3750X-48 and other IOS based switches: %SYS-7-NV_BLOCK_INIT: Initialized the geometry of nvram %SYS-5-RELOAD: Reload requested by Hulc LED Process. Reload Reason: Reason unspecified. The device will then reset and the configuration will not be present when it comes back up.
