Since upgrading to 220.127.116.1155 I have a series of Nexus switches that all are defined with the same SNMP V3 configuration at the group level. I have one device defined by IP Address in 2 different locations, using same SNMP V3 configuration. One will fail within the group with an SNMPERR_AUTHENTICATION_FAILURE (SNMP error #35) or one of the two identical devices will fail while the other remains up.?? I am monitoring SNMP up time as well as specific interfaces. The uptime sensors always comes back up with an uptime of 57+ days, indication no actual down time.?? I have tried changing the SNMP settings to Failed Requests Retry (recommended) to *Do not retry* & the devices worked fine yesterday. Today they are bouncing up & down again for no reason. I also added SNMP Delay (ms) 5 under SNMP Compatability but that doesn't seem to have helped either. The devices in question are Cisco Nexus Switches N7Kc7010 & N5kC5596Up. Any help would be greatly appreciated!!
Is there any documentation available for best practices for SNMP monitors?
