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.
When the switch is in VTP transparent mode, you can assign VLAN IDs greater than 1006, but they are
Note
not added to the VLAN database. See the
page
For the list of default parameters that are assigned when you add a VLAN, see the
Normal-Range VLANs" section on page
Beginning in privileged EXEC mode, follow these steps to use config-vlan mode to create or modify an
Ethernet VLAN:

Purpose
Enter global configuration mode.
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
(Optional) Enter a name for the VLAN. If no name is entered for the
VLAN, 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.
(Optional) Change the MTU size (or other VLAN characteristic).
(Optional) Configure the VLAN as the RSPAN VLAN for a remote
SPAN session. For more information on remote SPAN, see
"Configuring SPAN and RSPAN."
