Creating Access and Trunk Ports
To create access and trunk ports, use the following commands.
• Access port — a port on the service provider edge that directly connects to the customer. An access port may belong to only
one service provider VLAN.
• Trunk port — a port on a service provider bridge that connects to another service provider bridge and is a member of multiple
service provider VLANs.
Physical ports and port-channels can be access or trunk ports.
