SNMP polling overview
After the initial discovery and modeling of the topology objects for a specific routing protocol, updates the status of the objects by continuously monitoring
the devices through either SNMP or CLI polling. The results of the polling, in addition to the status updates extracted from SNMP traps and syslog messages (optional and applicable only to BGP and OSPF) and the status updates received from
IP Availability Manager
, serve as input to the correlation analysis.For SNMP polling, uses an IPv4 SNMP poller, which sends SNMPv1, v2c, or v3 messages for use with IP version 4. Authentication and privacy protocol support
for SNMPv3 identifies the authentication and privacy protocol support
for SNMPv3.
