Flushing Mappings from the Cache (CLI)
DNS-Less Operation
If the appliance is unable to access any DNS servers from its installed location in the network,
you may elect to operate without DNS by supplying the server address 127.0.0.1. To operate
without DNS:
■
BUI: Go to Configuration > Services > DNS. In the field for DNS Server(s), enter
127.0.0.1.
■
CLI: Go to configuration services dns and enter show. Enter set servers=127.0.0.1,
and then enter commit.
Use of this mode is strongly discouraged, because several features will not work correctly,
including:
■
Analytics will be unable to resolve client addresses to host names.
■
The Active Directory feature will not function (you will be unable to join a domain).
■
Use of SSL-protected LDAP will not work properly with certificates containing host names.
■
Alert and threshold actions that involve sending e-mail can only be sent to mail servers on
an attached subnet, and all addresses must be specified using the mail server's IP address.
■
Some operations may take longer than normal due to hostname resolution timeouts.
These limitations may be partially mitigated by using an alternate host resolution service; see
“Non-DNS Resolution” on page 312.

IPMP Configuration
IPMP (Internet Protocol Network Multipathing) allows multiple network interfaces to be
grouped as one, for both improved network bandwidth and reliability (interface redundancy).
Some properties can be configured in this section. For the configuration of network interfaces in
IPMP groups, see “Network Configuration” on page 55.
