Chapter 12 Configuring VLANs
Configuring Normal-Range VLANs
Creating or Modifying an Ethernet VLAN
Each Ethernet VLAN in the VLAN database has a unique, 4-digit ID that can be a number from 1
to 1001. VLAN IDs 1002 to 1005 are reserved for Token Ring and FDDI VLANs. To create a
normal-range VLAN to be added to the VLAN database, assign a number and name to the VLAN.
Note When the switch is in VTP transparent mode, you can assign VLAN IDs greater than 1006, but they are
not added to the VLAN database. See the “Configuring Extended-Range VLANs” section on
page 12-11.
For the list of default parameters that are assigned when you add a VLAN, see the “Configuring
Normal-Range VLANs” section on page 12-4.
Beginning in privileged EXEC mode, follow these steps to use config-vlan mode to create or modify an
Ethernet VLAN:
Translational bridge 1 0 0–1005
Translational bridge 2 0 0–1005
VLAN state For VLAN 1: active
For VLAN 2: active
active, suspend
Remote SPAN disabled enabled, disabled

Parameter Default Range
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
vlan vlan-id Enter a VLAN ID, and enter config-vlan mode. Enter a new VLAN ID
to create a VLAN, or enter an existing VLAN ID to modify a VLAN.
Note The available VLAN ID range for this command is 1 to 4094.
For information about adding VLAN IDs greater than 1005
(extended-range VLANs), see the “Configuring
Extended-Range VLANs” section on page 12-11.
Step 3
name vlan-name (Optional) Enter a name for the VLAN. If no name is entered, the default
is to append the vlan-id with leading zeros to the word VLAN. For
example, VLAN0004 is a default VLAN name for VLAN 4.
Step 4
mtu mtu-size (Optional) Change the MTU size (or other VLAN characteristic).
Step 5
end Return to privileged EXEC mode.
Step 6
show vlan {name vlan-name | id vlan-id} Verify your entries.
Step 7
copy running-config startup config (Optional) If the switch is in VTP transparent mode, the VLAN
configuration is saved in the running configuration file as well as in the
VLAN database. This saves the configuration in the switch startup
configuration file.
