41 Using MLAG in Dell Networking N-Series Switches | version 1.5
8 VoIP and MLAG Example
MLAG is compatible with Voice VLAN and QoS for VoIP deployments. The following example provides
instruction on setting up MLAG, RSTP-PV, and Voice VLAN, as well as configuring QoS for voice traffic
prioritization. This allows for the combination of a highly robust, non-blocking architecture provided by MLAG
with the fast-converging loop mitigation provided by RSTP-PV with the assurance of stutter-free voice traffic
should the network encounter contention.
The scenario in Figure 27 combines MLAG, RSTP-PV, Voice VLAN, and QoS settings for VoIP prioritization.
