CHAPTER 32 HA Configuration
Parameter
'Ping Count'
ping-count
[HaNetworkMonitor_
PingCount]
'Entry Reachability
Status'
Once you have configured the destinations to monitor, you can view the status of each destination
of a selected monitored row, as described in the following procedure.
➢
To view reachability status of destinations per monitored row:
1. Open the HA Network Monitor table (Setup menu > IP Network tab > Core Entities folder >
HA Network Monitor).
2. In the table, select the required index row (monitored row), and then click the HA Network
Monitor Peers Status link located below the table; the HA Network Monitor Peers Status
table appears, displaying the reachability status of each destination ('Peer Destination
Address') of the monitored row, as shown in the below example:
If the device receives a reply from a destination within this timeout, it
considers the destination as online (reachable). If no reply has been
received from a user-defined number of consecutive pings (see the
'Ping Count' parameter, below), the device considers the destination
as offline (unreachable).
The valid value is 100 to 60000. The default is 1000.
Defines the number of consecutive failed pings (no replies) before the
device considers the destination as offline (unreachable). For
example, if you configure the parameter to 2, the destination is
considered unreachable after 2 consecutive pings evoked no reply. If
this destination later replies to any subsequent ping, the device
considers it reachable.
The valid value is 1 to 10. The default is 3.
Note: If the destination has never replied to a ping, the device does
not consider it unreachable. Instead, it considers it as undetermined
("Reachability Unverified").
Read-only field displaying the connectivity (reachable) status with the
monitored row, which is based on ping results of all its configured
destinations:
■ "Reachability Unverified": The reachability status of the
monitored row is currently undetermined. In other words, all the
destinations configured for the monitored row have never replied
to the device's pings.
■ "Reachable": The device considers the monitored row as online
(reachable). In other words, the device has received a ping reply
from at least one of the destinations configured for the monitored
row.
■ "Not Reachable": The device considers the monitored row as
offline (unreachable). In other words, the number of failed pings
equals to (or is greater than) that configured by the 'Ping Count'
parameter, for all the destinations configured for the monitored
row and on condition that all these destinations have replied in the
past to the device's pings. The status of the monitored row returns
to "Reachable" if at least one of the destinations replies to a ping.
