1.3.a Access ports
Typically, an access port is used by a host to gain entry onto the network via an access layer switch.
An access port can have only one VLAN configured on an interface, meaning it can carry traffic for only a single vlan.
However, for completeness there is also an access port type known as muliti-vlan access whereby the voice vlan feature is enabled along with the switchport access vlan X command to support data and voice simultaneously. But that is another discussion.
Let’s default the interface first
and sh vlan brief
Shows us all of the ports are assigned to vlan 1 out of the box
Then examine the operational mode GOT season 7 with show interface f0/11 switchport
other useful interface commands are
sh int f0/11
sh run int f0/11
sh int f0/11 status
sh int descr
To enable a port for use with a Vlan use
switchport mode access,
Note that if the vlan has not already been created using the vlan X command, it will be created as a result of the switchport access vlan X command as demonstrated here:
switchport access vlan 10
There is also a macro command that will cause an access port to become a host port immediately
This will set it as access, enable spanning-tree portfast and will not allow it to become a member of an etherchannel
