• Enable or disable Reverse DNS Lookup . This feature is disabled by
default. Enabling this feature is the recommended configuration, unless
you have no DNS server configured or have poor network performance
because of heavy network traffic. With
Reverse DNS Lookup enabled,
when a network-related event occurs, reverse DNS lookup logs both
the IP address and the domain name for the networked device
associated with the event in the event log. If no domain name entry
exists for the device, only its IP address is logged with the event. Since
domain names generally change much less frequently than IP
addresses, enabling reverse DNS lookup can improve the ability to
identify addresses of networked devices that are causing events to
occur.
Ping utility (control console)
Select this option, available only in the control console, to check the Battery
Management System’s network connection by testing whether a defined IP
address or domain name responds to the Ping network utility. By default,
the default gateway IP address (see
TCP/IP ) is used. However, you can
use the IP address or domain name of any device known to be running on
the network.
