Physical Network Separation Mode - AudioCodes Mediant 3000 User Manual

10.9.4.3 Physical Network Separation Mode

When the device operates in the multiple IP interfaces scheme, it uses a single physical
Ethernet port (located on its RTM) to connect to these networks. Using VLAN tags and an
external VLAN-aware switch, the traffic can be directed to separate physical networks. In
contrast, in the Physical Network Separation mode, supported only when the device houses
a TP-8410 blade, each application type (OAMP, Call Control and RTP Media) has its own
dedicated physical Ethernet port. The device splits the traffic between these different
application types into different physical ports. This Physical Network Separation feature
eliminates the need for a VLAN-aware switch using VLAN tags to separate the different
traffic of each network. In this mode, the device actually implements the same scheme
internally. This means that VLAN tags are used internally, but traffic is not sent or received
with VLAN tags.
Physical Network Separation can be configured in the Web (or by using the ini file
parameter EnableNetworkPhysicalSeparation).
Notes:
Each of the TP-8410 blades (Active and Redundant) has its own dedicated and redundant
physical GBE port for Media traffic. This interface is directly available through the RTM. The
other four Ethernet ports are available through the PEM module, but are shared by both
blades. The active blade is the one connected to these ports.
The physical interfaces are summarized as follows:
Media network interface: provided by the Gigabit Ethernet port on the RTM-8410.
The Control and OAMP network interfaces are provided by the 10/100BaseT Ethernet
ports located on the two Power Entry Modules (PEM), as follows:
•
Control network interface: Ethernet ports labeled 1A (bottom PEM module) and
1B (top PEM module)
•
OAMP network interface: Ethernet ports labeled 2A (bottom PEM module) and
2B (top PEM module)
SIP User's Manual
•
Physical Network Separation is supported only for Mediant 3000 housing
TP-8410.
•
Physical Network Separation supports three interfaces (OAMP, Control,
and Media) and all three must be configured when operating in Physical
Network Separation mode.
•
When the Physical Network Separation mode is enabled, user VLANs are
not supported.
•
When operating in this mode, OAMP traffic is sent and received from/to
the designated physical port (i.e., on the PEM); when operating with a
single physical interface, the GbE port on the RTM-8410 is used.
