Configuring VLANs 603
Configuring a Port in Access Mode
Beginning in Privileged EXEC mode, use the following commands to 
configure an untagged layer 2 VLAN interface and assign the interface to a 
VLAN. When a port is in access mode, it can only be a member of one 
untagged VLAN. When you configure the interface as a VLAN member, the 
interface is automatically removed from its previous VLAN membership. You 
can configure each interface separately, or you can configure a range of 
interfaces with the same settings.
