DT-6061 User's Manual - Platform (Build 17.1)
12/14/09 Datatek Applications Inc. 27
The IP address and subnet mask are used to determine whether a destination IP address is on
the same LAN segment, or if a gateway hop is required. If it is necessary to reconfigure a DT-
6XXX to a new subnetwork, first set the gateway to none, then change the ipaddr, then set the
new gateway.
When one of these commands is invoked without its argument, it will display the current
configuration of the unit. When invoked with its argument, the current configuration is changed
accordingly.
When this DT-6061 is run in the high availability configuration as part of a duplex pair, two other
IP addresses are required. The ipaddr, ipother, and ippublic, must be part of the same
subnetwork as defined by the submask.
Syntax: ippublic [d.d.d.d]
ipother [d.d.d.d]
The address ipother is the IP address of the other/companion DT-6061 in the pair. The address
ippublic is the shared address of both units. Only one unit is active at a time.
Before configuring a pair of DT-6061’s for high availability, they should each be configured with
their own ipaddr, and with the appropriate gateway, and submask. The two DT-6061's must be
on the same network, which is to say the IP addresses of the two DT-6061s must have the same
network ID. See section 6.9 for additional detail and commands regarding the High Availability
feature.
Changes to these system parameters do not become effective until after the next reboot.
6.4.4 GATEWAY
Syntax: gateway [d.d.d.d]
The gateway command is only allowed when the unit is logged in.
The [d.d.d.d] field is the IP address of the gateway router to be used to reach a destination IP
address on a different LAN segment. Invocation of the command with no arguments causes it to
output the current value for gateway. The gateway must be in the same subnetwork as ipaddr
as defined by the submask.
When one of these commands is invoked without its argument, it will display the current
configuration of the unit. When invoked with its argument, the current configuration is changed
accordingly.
The gateway must belong to the same subnetwork as the module. That is, the part of the
gateway address corresponding to the non-zero part of the submask must match the
corresponding part of the ipaddr. If it is necessary to reconfigure a DT-6061 to a new
subnetwork, first set the gateway to none, then change the ipaddr, then set the new gateway.
Changes to these system parameters do not become effective until after the next reboot.
6.4.5 IP ADDRESS(ES) AND GATEWAY – LOCAL
Syntax: local [simplex] ipaddr=[d.d.d.d] submask=[d.d.d.d]
gateway=[d.d.d.d] [duplex] ippublic=[0.0.0.0] ipother=[0.0.0.0]
The local command is only allowed when the unit is logged in. The local command configures
the IP addresses and subnet mask of the unit with a single command, thus combining the
separate operations of the ipaddr, submask, ippublic, ipother, and gateway commands. All
parameters are optional; the command prompts for any required parameters.
