Data Sheet

Zarlink Semiconductor Inc.
Unmatched traffic is also forwarded to the CPU using queue 0. This allows the CPU to analyse the traffic to
work out what should be done with it. Alternatively, if the drop threshold on queue 0 is set very small,
unmatched traffic can be automatically discarded.
6.8.2 Example Classification Scheme
The following example shows how to set up the packet classification for a typical expected scenario. The
MT9088x is expecting the following four classes of traffic:
1.
2.
3.
4.
5.
TDM traffic using the protocol stack Ethernet - VLAN - CDP
TDM traffic using the protocol stack Ethernet - IPv4 - UDP - CDP
Data traffic to an external DSP using the protocol stack Ethernet - IPv4 - xxx
CPU control traffic using the protocol stack Ethernet - IPv4 - TCP - xxx
All other traffic - routed by default to CPU queue 0
Traffic Class 1: Ethernet - VLAN - CDP
Configure the mask and match registers in the packet engine to direct TDM traffic to the WAN interface.
