Mediant 4000 SBC | User's Manual
The device is shipped with a default OAMP interface (see Default IP Address ). The IP Interfaces
table lets you change this OAMP interface and configure additional network interfaces for control
and media, if necessary. You can configure up to 1,024 interfaces, consisting of up to 1,023 Control
and Media interfaces including a Maintenance interface if your device is deployed in a High
Availability (HA) mode, and 1 OAMP interface. Each IP interface is configured with the following:
■ Application type allowed on the interface:
● Control: call control signaling traffic (i.e., SIP)
● Media: RTP traffic
● Operations, Administration, Maintenance and Provisioning (OAMP): management (i.e.,
Web, CLI, and SNMP based management)
● Maintenance: This interface is used in HA mode when two devices are deployed for
redundancy, and represents one of the LAN interfaces or Ethernet Groups on each device
used for the Ethernet connectivity between the two devices. For more information on HA
and the Maintenance interface, see
Configuring High Availability .
■ IP address (IPv4 or IPv6) and subnet mask (prefix length)
■ Default Gateway: Traffic from this interface destined to a subnet that does not meet any of the
routing rules (local or static) are forwarded to this gateway.
■ (Optional) Primary and secondary domain name server (DNS) addresses for resolving FQDNs
into IP addresses.
■ Ethernet Device: Layer-2 bridging device and assigned a VLAN ID. As the Ethernet Device is
associated with an Ethernet Group, this is useful for setting trusted and un-trusted networks on
different physical Ethernet ports. Multiple entries in the IP Interfaces table may be associated
with the same Ethernet Device, providing multi-homing IP configuration (i.e., multiple IP
addresses on the same interface/VLAN).
Complementing the IP Interfaces table is the Static Routes table, which lets you configure static
routing rules for non-local hosts/subnets. For more information, see
Configuring Static IP Routing .
Before configuring the IP network interfaces, read the following guidelines:
■ One OAMP IP interface must be configured and this must be an IPv4 address. The OAMP
interface can be combined with Media and Control.
■ At least one Media-type interface must be configured.
■ At least one Control-type interface must be configured.
