Assigning Static-Access Ports to a VLAN

Original article can be found here: https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2950/software/release/12-1_11_yj4/configuration/guide/lrescg/swvlan.html#wp1036007


You can assign a static-access port to a VLAN without having VTP globally propagate VLAN configuration information (VTP is disabled). If you are assigning a port on a cluster member switch to a VLAN, first use the rcommand privileged EXEC command to log in to the member switch.


Note If you assign an interface to a VLAN that does not exist, the new VLAN is created. (See the "Creating or Modifying an Ethernet VLAN" section.)

Beginning in privileged EXEC mode, follow these steps to assign a port to a VLAN in the VLAN database:

 
Command
Purpose
Step 1

configure terminal

Enter global configuration mode

Step 2

interface interface-id

Enter the interface to be added to the VLAN.

Step 3

switchport mode access

Define the VLAN membership mode for the port (Layer 2 access port).

Step 4

switchport access vlan vlan-id

Assign the port to a VLAN. Valid VLAN IDs are 1 to 4094; do not enter leading zeros.

Step 5

end

Return to privileged EXEC mode.

Step 6

show running-config interface interface-id

Verify the VLAN membership mode of the interface.

Step 7

show interfaces interface-id switchport

Verify your entries in the Administrative Mode and the Access Mode VLAN fields of the display.

Step 8

copy running-config startup-config

(Optional) Save your entries in the configuration file.

To return an interface to its default configuration, use the default interface interface-id interface configuration command.

This example shows how to configure Fast Ethernet interface 0/1 as an access port in VLAN 2:

Switch# configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)# interface fastethernet0/1
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 2
Switch(config-if)# end
Switch#
