DNS Configuration
This page shows the active run-time settings for the domain name system (DNS) protocol.
The primary and secondary DNS addresses come from the active interface. The static
addresses from the Network Interface Configuration page may be overridden by DHCP or
BOOTP.
The DNS page also shows any contents in the DNS cache. When a DNS name is resolved
using a forward lookup, the results are stored in the DNS cache temporarily. The
PremierWave EN consults this cache when performing forward lookups. Each item in the
cache eventually times out and is removed automatically after a certain period, or you can
delete it manually.

Action Command

config-if:eth0# show

Syslog Configuration
The Syslog page shows the current configuration, status, and statistics of the syslog. Here
you can configure the syslog destination and the severity of the events to log.
Note: The system log is always saved to local storage, but it is not retained through reboots.
Saving the system log to a server that supports remote logging services (see RFC 3164)
allows the administrator to save the complete system log history. The default port is 514.
