The following fields can be set:

ParameterDescription

DNSR	Status This field can be toggled between
<Disabled>	Disabled and Enabled using the
	space bar, and is used to enable or
	disable the DNS Relay service on the
	switch.

Name Server:[1][2] Allows the entry of the IP address of a primary (number 1) and a secondary (number 2) domain name server (DNS).

DNSR Cache Status:<Disabled>

This can be toggled between Disabled and Enabled. This determines if a DNS cache will be enabled on the switch.

DNSR Static Table

Lookup

Status:<Disabled>

This field can be toggled using the space bar between Disabled and Enabled. This determines if the static DNS table will be used or not.

To make a static DNS table entry:

Select Static table configuration on the DNS Relay menu and press Enter.
