Step Description

Configure the code-point-aliases and classifier for Avaya VoIP traffic.

• The alias helps identify the binary DSCP setting by giving it a name.

• The sample network uses the name “avaya-rtp” to denote DSCP binary bit

101110 for media traffic. This is equivalent to the decimal Audio PHB Value

of 46 set in Avaya Communication Manager for RTP Media in Section 5, Step 8.

• The sample network uses the name “avaya-sig” to denote DSCP binary bit

100010 for signaling traffic. This is equivalent to the decimal Call Control

PHB Value of 34 set in Avaya Communication Manager for signaling in Section

5, Step 8.

• Define a classifier called “Avaya-voip”.

• The classifier “Avaya-voip” defines the forwarding characteristic of the router

based on traffic types.

• The network is configured to use expedited-forwarding with low loss-priority for

“avaya-rtp”, and assured-forwarding with low loss-priority for “avaya-sig”.
