I own several Cisco Nexus 7000 switch, each with several hundreds active network interfaces being monitored.
Every 2-3 hours I receive an error message fro most of the interfaces:
|No response (check: firewalls, routing, snap settings of the device, IPs, SNMP version, community, passwords etc.) (SNMP error # -2003)|
The error is occurring on all snmp sensors (Cisco System Health/Traffic).
