Chapter 13 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.
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
With VTP version 1 and 2, if 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

Step 2
vlan vlan-id
Enter a VLAN ID, and enter VLAN configuration mode. Enter a new
VLAN ID to create a VLAN, or enter an existing VLAN ID to modify
that VLAN.

that VLAN.
Note
The available VLAN ID range for this command is 1 to 4094.

Step 3
name vlan-name
(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.

VLAN 4.
Step 4
mtu mtu-size
(Optional) Change the MTU size (or other VLAN characteristic).
Step 5
remote-span
(Optional) Configure the VLAN as the RSPAN VLAN for a remote
SPAN session. For more information on remote SPAN, see
SPAN session. For more information on remote SPAN, see
Note
The switch must be running the LAN Base image to use RSPAN.
Step 6
end
Return to privileged EXEC mode.
Step 7
show vlan {name vlan-name | id vlan-id} Verify your entries.
Step 8
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.
