Services
This section describes the services the Mediatrix 1204 uses and their settings. Most of these services require
that you define their IP address and, if required, port number. See
“DHCP Server Configuration” on page 129
for more details.
Configuration variables of network parameters are defined in the MIB structure under the ipAddressConfig
folder. This folder is subdivided into groups, one for each service that requires a network parameter.
Configuration Source
The configuration your Mediatrix 1204 uses can either be:
dynamically assigned (network parameters assigned by a DHCP Server)
static (network parameters you manually defined in the MIB structure)
You can also set these parameters via the web interface, as described in “Network Settings” on page 35 .
DHCP Configuration
Using DHCP-assigned IP addresses ensures that the Mediatrix 1204 receives the addresses that are stored
in the DHCP server. This assumes that you have previously set the DHCP server with the proper values. See
“DHCP Server Configuration” on page 129 for more details.
The Mediatrix 1204 can receive numerous information from the DHCP server, including the vendor or site
specific information. Note that the Mediatrix 1204 does not make a DHCP request in the following cases:
If all MIB variables xxSelectConfigSource are set to static at start-up.
If one of the MIB variables xxSelectConfigSource is set to dhcp after the initialization process.
Verifying the DHCP-Assigned IP Addresses
You can query the MIB structure to see the IP addresses that have been assigned to the Mediatrix 1204.
Those IP addresses are located under the
ipAddressStatus folder in read-only variables.
This assumes that you know the local host IP address. There are two ways to get the local host IP address of
a Mediatrix unit:
With a telephone connected to the SCN or PBX, dial the number corresponding to one of the
SCN lines or analog PBX extensions connected to the Mediatrix 1204. After a few seconds, the
unit plays a second dial tone. Dial “*#*0” and listen for the IP address that is given.
Static Configuration
Using static IP addresses allows you to bypass the DHCP server or still be able to use the Mediatrix 1204 if
you are not running a DHCP server.
In this case, having one or more configuration source variable set to DHCP slows down the restart process. If
any information is set to come from the DHCP server (for example, SNTP address), the restarting unit waits
for a maximum period of two minutes if the DHCP server cannot be reached, even if most other settings are
set to “static”.
The reason for this delay is that the Mediatrix 1204 cannot function as configured if part of its configuration
(the DHCP information) is unavailable. To avoid this problem, you can set all configuration sources the
Mediatrix 1204 supports to “static”.

To set all configuration sources to static:
1. In the sysAdminMIB , set the sysAdminCommand variable to setConfigSourcesStatic .
In the Unit Manager Network Administration Manual , refer to chapter Performing Actions on Mediatrix Units ,
section Removing all DHCP Options .
