I know 
switchport access vlan "number"
is used to assign a port to a vlan. But what if I want a port to belong to two vlans, how do I do it?

    If I remember correctly that would mean you would need 802.1q compliant hardware that allows port tagging to be enabled.

    If you do then your answer is: Setup port tagging.

    A single switch port can only be assigned to one VLAN.

    In order to communicate between 2 different VLANs you would need to introduce a layer 3 device, (layer 3 switch or a router) with an IP Plus IOS on it and configure the lab for "router on a stick" inter-VLAN routing.

    Are you (above poster) talking about access ports by chance?

    An access port belongs to and carries the traffic of only one VLAN (unless it is configured as a voice VLAN port). Traffic is received and sent in basic formats with no VLAN tagging.

    Why do you want do it?

    You can setup an auxiliary vlan on CatOS or a voice vlan on IOS if you want to support both a data vlan and voice vlan on a port.

    Otherwise you setup the port as a trunk port and configure it only allow the VLANs you want.
