The following information details existing device issues that have been discovered within other releases. In most cases, a resolution is included to address the issue.
Cisco Catalyst OS Switches - Auto Discovery SNMP
Issue: Auto Discovery with SNMP Credentials and Accounts, and Privilege Passwords may hang if the devices do not have names. For example: no name set on CAT OS Switches. Note that this may be prevalent in the CAT OS devices, due to the no name default setting on CAT OS Switches.
Resolution: Set the Name on the device. On CAT OS, use the set system name command in Enable mode.
