About polling groups and settings
Polling groups and settings for the Multicast Manager are accessible via the Polling
tab of the Polling and Thresholds Console.
Polling groups include the following
polling settings:
- 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.
You can customize polling groups and
settings as needed:
- Configure polling setting parameters
- Specify additional matching criteria to further limit group membership
Polling groups and their
settings
Following table lists the Multicast
Manager polling groups and 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 |
