Applicable Scenario
Applicable Scenario
Figure 9-5 shows
PCs and IP phones connecting to the Internet through switches. Because
the voice service is sensitive to delay and jitter, the priority of
voice data flows needs to be increased so that they can be preferentially
forwarded when congestion occurs.
Figure 9-5 Applicable scenario of the voice VLAN
Configure a voice VLAN based on the type of voice packets
sent by IP phones:
Configure MAC address-based voice VLAN when voice packets are
untagged or tagged with VLAN 0.
Configure VLAN ID-based voice VLAN when IP phones can obtain voice
VLAN information on the switch.
