4. DiffServ table:
• Layer-2 QoS values are assigned:
♦ For packets sent with DiffServ value of 46, set VLAN priority to 6
♦ For packets sent with DiffServ value of 40, set VLAN priority to 6
♦ For packets sent with DiffServ value of 26, set VLAN priority to 4
♦ For packets sent with DiffServ value of 10, set VLAN priority to 2
• Layer-3 QoS values are assigned:
♦ For Media Service class, the default DiffServ value is set to 46
♦ For Control Service class, the default DiffServ value is set to 40
♦ For Gold Service class, the default DiffServ value is set to 26
♦ For Bronze Service class, the default DiffServ value is set to 10
12.5.3.4 VoIP Interfaces with Multiple Default Gateways
Below is a configuration example using default gateways per IP network interface. In this
example, the default gateway for OAMP is 192.168.0.1 and for Media and Control it is
200.200.85.1.

A separate Static Routes table lets you configure static routing rules. Configuring the
following static routing rules enables OAMP applications to access peers on subnet
17.17.0.0 through the gateway 192.168.10.1 (which is not the default gateway of the
interface), and Media & Control applications to access peers on subnet 171.79.39.0
through the gateway 200.200.85.10 (which is not the default gateway of the interface).

12.6 Configuring Static IP Routes
The Static Routes table lets you configure up to 30 static IP routing rules. Static routes let
you communicate with LAN networks that are not located behind the Default Gateway that
is specified for an IP network interface in the IP Interfaces table, from which the packets
are sent. Before sending an IP packet, the device searches the Static Routes table for an
entry that matches the requested destination host/network. If an entry is found, the device
sends the packet to the gateway that is configured for the static route. If no explicit entry is
