Impact notifications generated by the Multicast Manager
The Multicast Manager correlates abnormal multicast conditions, or symptoms, with
notifications received from the IP Availability Managerand then calculates the impact these
have on objects in its repository. Through a correlation process, the Multicast Manager
identifies multicast root cause problems, and reports the root cause problems as well as key
symptoms to the Global Manager.
Following table lists the impact
notifications generated by the Multicast Manager for each type of managed object
class.
Multicast-specific class | Impact notification | Description of notification |
|---|---|---|
IGMPInterface | IGMPInterfaceImpacted | This IGMP interface cannot be reached due to a failure on the
host. The IGMP interface is not operational due to a Layer 2 or
Layer 3 failure. The
IGMPInterface class is a multicast-specific class that
is transparent to the user, and therefore was not
described in Chapter 2. IGMPInterface is a logical
interface that provides IGMP functionality. |
MulticastGroup | ImpactedByAnycast | The multicast group is impacted by failure of one or more
components within the anycast redundancy group that this group
is served by. |
MulticastGroup | ImpactedByUnderlyingFailure | The multicast group is impacted by the failure of a
device. |
MulticastRedundancyGroup | Impacted | The multicast functionality of this redundancy group is
impacted by a physical failure. |
MulticastService | MulticastImpacted | The multicast functionality of this device is impacted by a
physical failure. |
MulticastService | RPImpacted | The functionality of this Rendezvous Point is impacted by a
physical failure. |
MulticastService | MulticastUpstreamImpacted | This multicast service is impacted by a problem in an
upstream multicast device. |
PIMHop | Impacted | The multicast hop is not available due to physical or logical
failure. |
PIMInterface | PIMInterfaceImpacted | The PIM interface is not operational due to a Layer 2 or
Layer 3 failure. The
PIMInterface class is a multicast-specific class that is
transparent to the user, and therefore was not described
in Chapter 2. PIMInterface is a logical sub-interface
that transmits and receives multicast packets in
accordance with the PIM standard. It can be configured
in either dense, sparse, or dense-sparse mode. |
