Polling groups and settings for the Multicast Manager are accessible via the Polling tab of the Polling and Thresholds Console.
- SNMP—Configure polling intervals to monitor the PIM, IGMP, multicast groups and services, and MSDP session connections by probing the SNMP tables maintained by the SNMP agents of the multicast routing devices.
- External—Configure polling intervals used to monitor multicast components such as PIM and IGMP interfaces, multicast groups and services, and MSDP sessions. The analysis results are collected by an external process for test purposes. The external polling setting is used only for testing or demonstration purposes.
- Configure polling setting parameters
- Specify additional matching criteria to further limit group membership
Polling groups and their settings
|Polling group||Description||Polling setting|
|(S,G) Polling||Allows you to set the polling parameters for SG objects, including filtering or creation of polling groups according to different criteria (e.g., whether an SG belongs to a DR). Polling is done for SG incoming/outgoing packet counters, and for the prune flag. Note that the (S,G) Polling group can be applied to all PimSGEntry classes (that is,*,G and S,G groups).||
|IGMP Interface Polling||Allows you to set the IGMP interface polling parameters. This is used for polling IGMP interface oper status, and counters of joins and leaves.||
|MSDP Session Polling||Allows you to set the MSDP session polling parameters. This is used for polling MSDP session peer state.||
|Multicast Service Polling||Allows you to set the multicast service polling parameters. It is used for polling the number of SG entries in the device, and MSDP entries in the cache.||
|PIM Interface Polling||Allows you to set the PIM interface polling parameters. It is used for polling PIM interface status and DR address changes||
Polling setting parameters
Following table lists the Multicast Manager polling groups and setting parameters.
|Enables or disables Multicast Manager connectivity/performance analysis; if analysis mode is disabled, no polling is performed.|
|PollingInterval||30 to 3600 seconds
Default: 240 seconds
|Sets the time between successive polls.|
|Retries||0 to 10 retries
|Sets the number of retry polls to perform when the initial poll fails.|
|Timeout||10 to 10000 milliseconds
Default: 700 milliseconds
|Sets the amount of time allowed for the first poll request before it times out. Successive retries use longer times.|
