You can monitor multicast groups and routes to determine
whether there are any events on the devices in those groups and routes.
About this task
PIM groups, IGMP groups, and IP Multicast routes can only
be monitored if the discovery has been configured to discover them.
Views for these groups and routes are created automatically; you can
also create them manually.
To monitor multicast groups, complete
the following tasks.
Procedure
-
Click the Incident icon and select .
- In the navigation tree on the left of the widget, click the + symbol to expand the
IGMP Groups node. A list of the IGMP groups
that have been discovered is displayed.
- In the navigation tree on the left of the widget, click the + symbol to expand the
PIM network node. A list of the PIM groups
that have been discovered is displayed.
- In the navigation tree on the left of the widget, click the + symbol to expand the
Multicast Routing MDTs node. A list of the IP
multicast routes that have been discovered is displayed. Multicast Distribution Trees (MDTs) are
named according to the (source, group address) notation. For example, an (S,G) notation of
(172.20.1.6,224.0.0.1) shows that a device with an IP address of 172.20.1.6 is a source sending data
to the 224.0.0.1 group.
- Determine the most severe event in each group based on
the associated event status icon.
