duplex, while 'auto' allows auto-configuration. The 'phy' configuration is independent for the two
machines in a redundant configuration. The interface has to be set in each machine. This
command is used in conjunction with the delay parameter of the stby cfg (in section 6.9.3)
command only when necessary. The recommendation is to not set the value for phy, which means
it will default to auto.

In this version of the platform software, coupled with newer software versions of DT-6X60
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-6X60 reboots (or, in the case of a redundant DT-6X60, when
switchover between active and standby occurs). The special treatment accelerates the
reestablishment of TCP connections between applications on the DT-6X60 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-6X60 and other Datatek products. To enable the DT-
6X60 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-6X60 and other Datatek network elements very quickly after a DT-
6X60 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-6X60 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-
6X60, then it is beneficial to add 'B' to the dtproduct configuration for this DT-6X60.
If a DT-4XXX or UMI at address 'C' has been permanently removed from the network or no
longer has connections configured with this DT-6X60, it is beneficial to delete 'C' from the
dtproduct configuration of this DT-6X60.
The absence of one or more DT-4XXX's from the network when they occur in the dtproduct
list on a DT-6X60 can cause up to a 10-second (total) delay when rebooting that DT-6X60.

There is very little overhead in adding 'D' to a dtproduct configuration of a DT-6X60, as long
as the DT-4XXX associated with 'D' is usually up and running when this DT-6X60 is rebooted;
otherwise the 10 second boot delay described above may apply. However, a list larger than 40
or 50 should be carefully managed.
