Search Domains
A list of search domains used by the ExtremeAnalytics engine when doing lookups
by hostname. When an attempt to resolve a hostname is made, these domain
suffixes are appended to the hostname of the device. For example, if someone does
a ping to server1, ExtremeAnalytics appends the search domains in an attempt to
resolve the name: server1.domain1 server1.domain2, and so on.
DNS Servers
A list of DNS servers the ExtremeAnalytics engine sends DNS lookups to for name
resolution. The list is used by both hostname resolution and by the DNS proxy. Click
the Add button to open a blank box in which you can enter an IPaddress. Select an
IPaddress in the table and click the Delete button to remove an IPaddress. You can
enter multiple servers for redundancy. Use the Up and Down arrows to list the
servers in the order they should be used.
NTP
Select the Manage NTP Configuration checkbox to open the NTP (Network Time
Protocol) Servers area. NTP configuration is important for protocols such as
SNMPv3 and RFC3576 which incorporate playback protection. In addition,
having accurate time configured on the ExtremeAnalytics engine is essential for
event logging and troubleshooting.
