may choose: 
Access - Access ports are for connecting Switch VLANs to customer VLANs.  
Uplink - Uplink ports are for connecting Switch VLANs to the Provider VLANs on a remote 
source.  
Port List 
Use the From and To fields to set a list of ports to be placed in, or removed from, the Service 
Provider VLAN. The port list is specified by listing the lowest switch number and the beginning 
port number on that switch, separated by a colon. Then the highest switch number and the 
highest port number of the range (also separated by a colon) are specified. The beginning and 
end of the port list range are separated by a dash. For example, 1:3 specifies switch number 1, 
port 3. 2:4 specifies switch number 2, port 4. 1:3 - 2:4 specifies all of the ports between switch 1, 
port 3 and switch 2, port 4 − in numerical order. Entering all will denote all ports on the Switch.
