Assigning Static-Access Ports To A Vlan - Cisco 3845 - Security Bundle Router Software Manual

Creating and Modifying VLANs
To return the VLAN name to the default settings, use the no name or no mtu VLAN configuration
command.
This example shows how to create Ethernet VLAN 20, name it test20, and add it to the VLAN database:
Switch# configure terminal
Switch(config)# vlan 20
Switch(config-vlan)# name test20
Switch(config-vlan)# end
This example shows how to create a new extended-range VLAN with all default characteristics, enter
config-vlan mode, and save the new VLAN in the switch startup configuration file:
Switch(config)# vlan 2000
Switch(config-vlan)# end
Switch# copy running-config startup config

Assigning Static-Access Ports to a VLAN

You can assign a static-access port to a VLAN.
If you assign an interface to a VLAN that does not exist, the new VLAN is created. (See the
Note
or Modifying an Ethernet VLAN" section on page
Beginning in privileged EXEC mode, follow these steps to assign a port to a VLAN in the VLAN
database:
Command
Step 1 configure terminal
Step 2 interface interface-id
Step 3 switchport mode access
Step 4
switchport access vlan vlan-id
Step 5
end
Step 6
show running-config interface interface-id
Step 7
show interfaces interface-id switchport
Step 8 copy running-config startup-config
To return an interface to its default configuration, use the default interface interface-id interface
configuration command.
This example shows how to configure a port as an access port in VLAN 2:
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# interface gigabithernet0/1
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 2
Switch(config-if)# end

Purpose
Enter global configuration mode
Enter the interface to be added to the VLAN.
Define the VLAN membership mode for the port (Layer 2 access
port).
Assign the port to a VLAN. Valid VLAN IDs are 1 to 4094.
Return to privileged EXEC mode.
Verify the VLAN membership mode of the interface.
Verify your entries in the Administrative Mode and the Access Mode
VLAN fields of the display.
(Optional) Save your entries in the configuration file.
End with CNTL/Z.
