Hello @bc230210154iah,
you can typically configure a port to be a member of one VLAN at a time. This means that you can assign a single VLAN ID to a port, and traffic on that port will be associated with that VLAN. However, you can configure multiple ports on the switch to belong to different VLANs.
If you need to have multiple VLANs on a single port, you can achieve that by using VLAN trunking. Trunking allows a single physical link to carry traffic for multiple VLANs by adding VLAN tags to the Ethernet frames. The VLAN tags indicate which VLAN each frame belongs to, allowing the switch to separate and route the traffic accordingly.
By using VLAN trunking protocols such as IEEE 802.1Q, you can have multiple VLANs on a single trunk port. The actual limit on the number of VLANs supported on a trunk port will depend on the switch's capabilities, such as the number of available VLAN IDs and the amount of memory allocated for VLAN information.

Access two (one data one voice VLAN)
trunk you can assign 4096 -(some VLAN-ID is preserved)

Only 1 for Data and 1 for Voice, so 2 in total
