Ping is a function for monitoring the communication status of network devices. By making ping settings for a destination system, you can detect when that system goes down. This improves the reliability of the network because, in addition to the link statuses, you can even determine the communication statuses of network devices.
Note
GLS can run without using ping monitoring, but, in that case, it will not be able to detect communication errors in network devices. It is recommended to use ping for improved network reliability. Note that ping can only monitor network devices with an IP address.
To use ping, make these settings for all physical adapters bundled in the virtual adapter. You cannot make these settings only for a single physical adapter in the bundle.
This section describes how to make ping settings, assuming the following criteria:
Virtual adapter: sha0
Physical adapters: Local Area Connection 1, Local Area Connection 2
IP addresses of switches: 192.168.2.10, 192.168.2.20
Figure 3.8 Ping Monitor Settings
Use the hanetpoll command to make ping settings. Note that you must be a member of the Administrators group to execute hanetpoll.
Specify the IP addresses (192.168.2.10 and 192.168.2.20) of the switches to be monitored for the physical adapters Local Area Connection 1 and Local Area Connection 2, and then execute the hanetpoll command.
> hanetpoll create -t "Local Area Connection 1" -p 192.168.2.10,192.168.2.20 FJSVhanet: INFO: 00000: The command ended normally. > hanetpoll create -t "Local Area Connection 2" -p 192.168.2.10,192.168.2.20 FJSVhanet: INFO: 00000: The command ended normally. |
Point
By setting a destination system as the ping target, you can detect whether or not there is a ping response from that system. You can also specify the switching behavior of adapters. For more details, refer to "6.2.4 hanetpoll."
