An S5120-EI switch supports up to eight voice VLANs globally.
You can configure different voice VLANs on different ports at the same time. However, one port
can be configured with only one voice VLAN, and this voice VLAN must be a static VLAN that
already exists on the device.
Voice VLAN is mutually exclusive with Link Aggregation Control Protocol (LACP) on a port.
To make voice VLAN take effect on a port which is enabled with voice VLAN and operates in
manual voice VLAN assignment mode, you need to assign the port to the voice VLAN manually.
