26.4 Configuring IP Network Connectivity on Media
Gateway Boards
Media Gateway boards (TP-6310 or TP-8410) send and receive all types of IP traffic:
OAM (management), Call Control and Media.
Configuration of the Media Gateway board's IP network connectivity is performed via
the following steps:

Configuring IP subnets for each network segment (subnet) to which the Mediant
8000 is connected. See 'IP Subnets' on page
198 for details.

Grouping IP subnets into Network Profiles. See 'IP Network Profiles' on page 200
for details.

Attaching each Media Gateway board to a corresponding Network Profile. See
'Attaching IP Network Profile to the Media Gateway Board' on page
201 for
details.

Configuring Media Gateway board’s IP Addresses for each subnet included in the
corresponding Network Profile. See 'Configuring Media Gateway Board’s IP
Addresses' on page
202 for details.
26.4.1 IP Subnets
In the simplest (default) IP network configuration, a single network segment (subnet) is
used to transmit all IP traffic to and from the Mediant 8000.
However in more complicated IP network architectures, different segments (subnets)
may be used to transmit different types of traffic, as described below:

OAM Subnet – used to transmit management traffic, e.g. SNMP, CLI (SSH),
Syslog and NTP.

Control Subnets – used to transmit call control traffic, e.g. MGCP, MEGACO
and SIP

Media Subnets – used to transmit media traffic, e.g. RTP.
The Mediant 8000 may be connected to one OAM Subnet, and up to ten Control and
Media Subnets. Mixed subnets may be used as well – e.g. a single subnet may be
used to transmit both OAM and Control types of traffic. See Types of IP Network
Traffic and Network Subnets for details.
For each IP network subnet available on the site to which the Mediant 8000 must be
connected, a corresponding configuration object – Subnet – must be defined. Each
Subnet configuration object defines the basic IP subnet properties, such as subnet IP
address, subnet mask and default gateway.
Since OAM subnet parameters are configured as part of basic network configuration
on SC boards (see 'Configuring IP Network Connectivity on SC Boards' on page 195
for details); a corresponding Subnet configuration object (with index 1) is created
automatically. This first Subnet, describing the OAM subnet, may not be deleted by
the user and only its traffic type may be configured as described below.
