2.3 ASSIGNMENT OF THE IP-LTCN APPLICATION TO INSTANCE 1
As stated earlier, the IP-LTCN application must be the only application installed on the DT-6061
and must be assigned to instance 1. To assign the instance, do the following:
<DT-6061> app 1 type=IP-LTCN ↵
↵↵
↵ configuring instance #1 for installed application
Stopping 1 none(55)
PID 1033 running IP-LTCN 1
The app command causes the application to be started after the command finishes configuring it
for instance 1.
At this point, from a PC or other device on the IP network, the administrator can telnet to port
10001, which is the console port number for the IP-LTCN application, in order to interact with the
application program directly. For example, the administrator can check the version of the IP-
LTCN via the following commands:
<IP-LTCN> login passwd=<initial | <password> >
<IP-LTCN> ver
The ver command output shows the current build number, software version, and database
version of the IP-LTCN. The build number can be compared with the list on the Datatek web site
that shows the current version of each application.
The administrator cannot access the application via the DT-6061 console; it must be done via
telnet only. On the other hand, all DT-6061 device commands must be performed via the DT-
6061 console.
2.4 SETTING UP THE REDUNDANT DT-6061
In order to configure a second DT-6061, repeat the steps in section 2.1, 2.2 and 2.3 for the
second DT-6061. Note that the second DT-6061 must have a unique IP address but it must use
the same subnetwork address portion as in the address of the first DT-6061. After completion of
these steps, both machines are now in-service but not in high-availability mode.
2.5 HIGH AVAILABILITY OPTION
The following sections (2.5 through 5) replace section 11 of the DT-6061 User’s Manual
(Platform). It reflects the usage of this option per the needs of the Tollgrade organization.
The High Availability option couples two DT-6061 modules as an active and a standby. The active
DT-6061 runs applications, while the standby "stands by" and monitors the active DT-6061. If the
active DT-6061 fails or loses power, the standby will shortly take over the active role.
In standby mode, the DT-6061 has completed system boot, but has not started applications. A
standby DT-6061 supports a subset of the commands in section 7 of the DT-6061 User manual
for the DT-6061 platform plus a small number of commands for support of high availability,
documented below. The prompt at the standby system console contains the word "standby".
Whenever a DT-6061 with high availability configuration boots, it first enters standby mode and
begins to poll the other DT-6061 every few seconds across the IP network that joins them. There
are three possible outcomes:
• The other DT-6061 doesn't respond (within a period of approximately 20 seconds), so this
standby becomes active.
