Voice Vlan Enable - H3C s3100 series Command Manual

The voice VLAN aging timer does not take effect on ports working in manual voice VLAN assignment
mode, because these ports are assigned to the voice VLAN statically.
When setting the voice VLAN aging timer, consider the usage frequency of IP phones. Note that:
A large voice VLAN aging timer setting can prevent a port from being assigned to or removed from
the voice VLAN frequently, keeping voice communication stable. However, this may cause a port to
stay in the voice VLAN even if it has not transmitted voice traffic for a long time, occupying system
resources and bringing about security problems. Therefore, you are recommended to set a large
voice VLAN aging timer in a network with credible network devices and many voice applications.
A small voice VLAN aging timer enables the switch to remove a port that has not transmitted voice
traffic from the voice VLAN timely, thus improving network security. However, this may cause the
port to be assigned to or removed from the voice VLAN frequently. Therefore, you are
recommended to set a small voice VLAN aging timer in a network with only a few voice
applications.
