Each ipaddr<n> field is the IP address of a Domain Name Server to be used to resolve domain-
style addresses not defined in the hosts table. The DNS IP addresses are used in the order
specified. If only one address is to be defined, it should be ipaddr1.
Each time the dns command is run, the user is prompted for all values except for those specified
on the command line. The user is prompted in the following order: name1, name2, name3,
ipaddr1, ipaddr2, ipaddr3. In order to delete a value, reply to a prompt with the word “none” or
on the command line, type the parameter name with no value following; for example,
dns ipaddr1= or
dns name2=
6.4.9 CONFIGURE ETHERNET INTERFACE – PHY- NOT VALID FOR DT-6061
This command is only applicable to and available on the DT-6160 and DT-6260.
6.4.10 MANAGE LIST OF COMPANION DT PRODUCTS – DTPRODUCT, VFY DTPRODUCT
Syntax: dtproduct: add|del <ipaddr> [<ipaddr> ...]
vfy dtproduct
dtproduct list | vfy
In this version of the platform software, coupled with newer software versions of DT-6XXX
applications and other Datatek products, TCP connection breakage is detected automatically.
The dtproduct command is no longer necessary when the user's network is running newer
software versions.
The dtproduct add command adds the given IP addresses to a list of network elements to be
treated specially whenever the DT-6XXX reboots (or, in the case of a redundant DT-6XXX, when
switchover between active and standby occurs). The special treatment accelerates the
reestablishment of TCP connections between applications on the DT-6XXX and those network
elements. Only Datatek-manufactured IP-based network elements, such as the DT-4XXX and the
UMI, are able to respond to this acceleration treatment. IP addresses are deleted from this list by
dtproduct del.
Under various conditions of equipment and network outage, it can sometimes take time (minutes)
for IP connections to close and reconnect. This special acceleration helps reduce downtime for
those connections between a rebooting DT-6XXX and other Datatek products. To enable the DT-
6XXX to use this feature, the user uses the optional dtproduct command to build a list of IP
addresses for which this feature is to be used. Properly configured, this feature helps reestablish
the connections between a DT-6XXX and other Datatek network elements very quickly after a
DT-6XXX is rebooted. Non-Datatek equipment will not respond to this treatment.
The dtproduct list may be viewed with the vfy dtproduct, dtproduct list, or dtproduct vfy
commands.
Note: This is an optional configuration to improve performance and reliability after network
equipment outages, and is not required for correct functionality.
Here are some guidelines to decide when to use the dtproduct command with older
software versions of these products:
If any application on the DT-6XXX has been configured to originate calls to a DT-4XXX or
UMI with IP address 'A', then it is beneficial to add 'A' to the dtproduct configuration.
If a DT-4XXX or UMI with IP address 'B' has been configured to originate calls to this DT-
6XXX, then it is beneficial to add 'B' to the dtproduct configuration for this DT-6XXX.
