Create Access and Trunk Ports
An access port is a port on the service provider edge that directly connects to the customer . An access port
may belong to only one service provider VLAN.
A trunk port is 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.
To create access and trunk ports:
Step
Task
1
Assign the role of access port to a Layer 2 port on a provider
bridge that is connected to a customer.
2
Assign the role of trunk port to a Layer 2 port on a provider
bridge that is connected to another provider bridge.
3
Assign all access ports and trunk ports to service provider
VLANs.
Display the VLAN-Stacking configuration for a switchport using the command
INTERFACE mode, as shown in
