on all the host interface ports of any attached Fabric Extender (FEX).
You can enable the vlan dot1q tag native command by entering the command in the global configuration

mode.
Configuring Access and Trunk Interfaces
Configuring a LAN Interface as an Ethernet Access Port
You can configure an Ethernet interface as an access port. An access port transmits packets on only one,
untagged VLAN. You specify which VLAN traffic that the interface carries. If you do not specify a VLAN
for an access port, the interface carries traffic only on the default VLAN. The default VLAN is VLAN1.
The VLAN must exist before you can specify that VLAN as an access VLAN. The system shuts down an
access port that is assigned to an access VLAN that does not exist.
SUMMARY STEPS
1. switch# configure terminal
2. switch(config)# interface {{type slot/port} | {port-channel number}}
3. switch(config-if)# switchport mode {access | trunk}
4. switch(config-if)# switchport access vlan vlan-id
DETAILED STEPS
Command or Action
Step 1
switch# configure terminal
Step 2

{access | trunk}
Step 4
switch(config-if)# switchport access vlan

Purpose
Enters global configuration mode.
Specifies an interface to configure, and enters interface configuration
mode.
Sets the interface as a nontrunking nontagged single-VLAN Ethernet
interface. An access port can carry traffic in one VLAN only. By default,
an access port carries traffic for VLAN1; to set the access port to carry
traffic for a different VLAN, use the switchport access vlan command.
Specifies the VLAN for which this access port will carry traffic. If you
do not enter this command, the access port carries traffic on VLAN1 only;
use this command to change the VLAN for which the access port carries
traffic.
