Network Protocol Manager for BGP diagnoses root-cause problems and detects (computes) events from status updates acquired in the following ways:
By subscribing to BGP-relevant status updates from IP Availability Manager
By using SNMP polling to gather status information from the BGP-enabled devices
By extracting status information from SNMP traps that are issued by the BGP-enabled devices
By extracting status information from syslog messages that are issued by the BGP-enabled devices
Network Protocol Manager for BGP correlates these events to diagnose root-cause problems.Note:
Events used as symptoms to diagnose a root-cause problem can also be perceived as impacts that are caused by the problem.
The Global Manager imports:
All problems that are diagnosed by Network Protocol Manager for BGP.
Key events that are detected by Network Protocol Manager for BGP.
The root-cause problem notifications (one problem per notification) and the event notifications (one event per notification) are displayed in the Global Console.Note:
In Network Protocol Manager, the range of notification for Cisco BGP-enabled devices in IPv6 network is limited. This is because the discovery and monitoring mechanism of Cisco BGP-enabled devices is CLI-based and not SNMP-based. The IPv6 notifications generated for Cisco devices are indicated in GUID-276137BF-6948-4BEF-A421-B527744F6535.html#GUID-276137BF-6948-4BEF-A421-B527744F6535___NPM_BGP_USER_ELEMENTS_82295 and GUID-276137BF-6948-4BEF-A421-B527744F6535.html#GUID-276137BF-6948-4BEF-A421-B527744F6535___NPM_BGP_USER_ELEMENTS_40962 against those notifications.
