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.
-
