5. Configuration Using the Web Interface
Media Realm Table
The Media Realm Table enables the user to divide an interface into several application
realms. The application realm is defined as a set of IPv4 and IPv6 interfaces and an
optional specification of the port range. The Media Realm Table is accessible from the
navigation tree on the left, by clicking on the Configuration - Protocol Configuration
- Media Realm Configuration link. The MEGACO Media Realm Table appears as
shown below.
Figure 5-118: MEGACO Media Realm Table
Using the Media Realm Table, the user may add a new Media Realm, edit an existing
one or remove an entry. The default control protocol media realm name, is also
configurable from this screen.
The Media Realm Table contains the following columns:
Table Index - This column holds the index of each interface. Possible values are 0 to
15. Each interface index must be unique.
Media Realm Name - This column allows the configuration of a short string (up to 40
characters) representing the name this realm. This name should be then used by the
IPDC/Realm property of the LocalControl descriptor in order to allocate IP address
from the specific realm. This column must have a unique value for each realm (no two
realms can have the same name) and must not be left blank.
IPv4 Name and IPv6 Name - These columns allow the user to associate IPv4 and/or
IPv6 interfaces to the realm. The IPv4/6IF columns should contain the name of the
IPv4/6 interface corresponding to the one appearing in the interface table.
The Port Range Start, Media Session Log and Port Range End columns allow the
user to associate the UDP port regions with the realm. These columns are optional. If
these columns are not configured, all realms will use the common default media port
pool. For more information, refer to the Product Reference Manual.
Port Range Start - This column is the starting port for the range of media ports.
Media Sessions - This column defines the number of media sessions associated with
the range of ports. It is the actual number of media sessions available to the user in
the port regions. For example, 100 ports correspond to 10 media sessions, since ports
are allocated in chunks of 10.
Port Range End – This column defines the ending port for the range of media ports. It
is a read-only field which is calculated by adding the Media Session field (multiplied
by the port chunk size) to the Port Range Start field. A value appears once a row has
been successfully added to the table.
A user may not configure some of the rows with a Port Range and some without. Port
ranges over 60000 should not be used. Ranges of realm ports should not overlap.
