SIP User's Manual 10. Networking Capabilities
10.6.1 Multiple Network Interfaces and VLANs
A need often arises to have logically separated network segments for various applications
(for administrative and security reasons). This can be achieved by employing Layer-2
VLANs and Layer 3 subnets.
Figure 10-2: Multiple Network Interfaces
This figure above depicts a typical configuration featuring in which the device is configured
with three network interfaces for:
„ Operations, Administration, Maintenance, and Provisioning (OAMP) applications
„ Call Control applications
„ Media
It is connected to a VLAN-aware switch, which is used for directing traffic from (and to) the
device to three separated Layer-3 broadcast domains according to VLAN tags (middle
pane).
The Multiple Interfaces scheme allows the configuration of up to 16 different IP addresses,
each associated with a unique VLAN ID. The configuration is performed using the Multiple
Interface table, which is configurable using the
ini file, Web, and SNMP interfaces.
