To view dynamic routes, take the following step:
„
Open the ‘Dynamic Routing Table' screen ( Advanced Configuration menu >
Network Settings > Dynamic Routes option).
Figure 6-22: Dynamic Routing Table Screen
From the ‘Dynamic Routing Table' screen you can view the static routes (i.e., access the 'Static
Routing Table' screen), by clicking the
Edit Static Routes button.
Table 6-20: Dynamic Routing Table Parameter Description
Column Name Description
Dest IP
IP address of the destination host / network.
Dest Mask Subnet mask of the destination host / network.
GW IP
IP address of the gateway router to which the packets are sent.
Interface The interface for routing to the destination.
Metric The Metric of the route.
State Indicates whether or not the route is active.
6.3.1.5 QoS
The Media Pack supports Quality of Service (QoS) features. The QoS feature allows you to
define the following:
„
Mark packets with QoS tags that can be used in the network to provide the requested
service quality for voice packets.
„
Limit the bandwidth of the WAN interface. This can be used if you have limited
upstream bandwidth. For example, if you have a 600 Kbit/s upstream ADSL link, you
can limit the MediaPack to not transmit more than 600 Kbit/s and thereby, prevent
packet loss on the ADSL link. A scheduler built into the MediaPack can be used to
prioritize voice packets.
The gateway supports a Weighted Fair Queuing (WFQ) traffic scheduler and rate limiter to
schedule outgoing packets. Packets are processed according to their priority. The behavior
of the scheduler is defined in a QoS profile. For the scheduler to operate correctly, you
must define the upstream bandwidth of the WAN link. The bandwidth is specified in kilobits
per second (kbps). For example, for a 2 Megabit link, you need to enter the value "2000"
(i.e., 2000 kbps). In addition to scheduling, the scheduler can mark packets with QoS
attributes. The network routing can use the marking to prioritize packets.
