Classifier-Based QoS Configuration Examples

QoS Policy for Voice over IP and Data Traffic
In this example, an administrator would like to configure the following Layer 2
802.1p CoS and Layer 3 DSCP values to prioritize how VoIP traffic from
different phones is handled compared to data traffic:
■ Softphone traffic: DSCP 46; 802.1p CoS priority 6
Avaya phone traffic: DSCP 34; 802.1p CoS priority 3
■
Miscellaneous phone traffic: DSCP 26; 802.1p CoS priority 3
■
■ Data traffic: DSCP 000000; 802.1p CoS priority 0
The following QoS configuration creates and assigns a QoS policy to VLAN 1
that prioritizes VoIP and data traffic in this way:
These match statements select traffic that satisfies multiple
criteria; for example, a TCP port range and a DSCP value or a
source IP address and a DSCP value.
