Default ping policies

Network Manager provides default poll policies for ping operations.

The following table provides information on the default ping poll policies.

Table 1. Default ping poll policies 
Poll Policy Name Description
Default Chassis Ping

Uses the Default Chassis Ping poll definition to ping all network devices. The type of device pinged is restricted by the Class Filter in the Default Chassis Ping poll definition.

This is the only poll policy to be enabled by default.
Default Interface Ping Uses the Default Interface Ping poll definition to perform ping operations on all interfaces that are within a main node with a valid IP address. This policy uses the Default Interface Ping poll definition to ping interfaces on all network devices. The interfaces pinged are restricted according to the following:
  • The interface filter in the poll definition. This can be further refined by adding extra poll definition filters.
  • The managed status of each interface. The managed status can be changed by using the Topoviz or the Structure Browser GUIs, or by using the ManagedNode.pl, UnManagedNode.pl, or RemoveNode.pl scripts.
End Node Ping Uses the End Node Ping poll definition to perform ping operations on all end nodes, as defined by the class settings.

ConfirmDeviceDown

Uses the Default Chassis Ping poll definition with an increased polling frequency and a policy scope that includes only those devices that on which an NmosPingFail event has occurred. This policy is used as part of an adaptive polling scenario and has the aim of accelerating ping polling of devices that failed to respond to a ping poll in order to identify devices that are really down.
