Configuring VLANs

Step 3
vlan vlan-id
Step 4
mtu mtu-size
Step 5

Step 6

Step 7
show vlan id vlan-id
Step 8
copy running-config startup config
To delete an extended-range VLAN, use the no vlan vlan-id global configuration command.
The procedure for assigning static-access ports to an extended-range VLAN is the same as for
normal-range VLANs. See the
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)# vtp mode transparent
Switch(config)# vlan 2000
Switch(config-vlan)# end
Switch# copy running-config startup config
Displaying VLANs
Use the show vlan privileged EXEC command to display a list of all VLANs on the switch, including
extended-range VLANs. The display includes VLAN status, ports, and configuration information. To
view normal-range VLANs in the VLAN database (1 to 1005), use the show VLAN database
configuration command (accessed by entering the vlan database privileged EXEC command).

VLAN Monitoring Commands
Command
show
show current [vlan-id]
OL-13018-01
Purpose
Enter an extended-range VLAN ID and enter config-vlan mode. The
range is 1006 to 4094.
(Optional) Modify the VLAN by changing the MTU size.
Note
Note
Return to privileged EXEC mode.
Verify that the VLAN has been created.
Save your entries in the switch startup configuration file. To save
extended-range VLAN configurations, you need to save the VTP
transparent mode configuration and the extended-range VLAN
configuration in the switch startup configuration file. Otherwise, if the
switch resets, it will default to VTP server mode, and the extended-range
VLAN IDs will not be saved.
"Assigning Static-Access Ports to a VLAN" section on page
lists the commands for monitoring VLANs.
Command Mode
VLAN database configuration
VLAN database configuration
Although all VLAN commands appear in the CLI help in
config-vlan mode, only the mtu mtu-size, and remote-span
commands are supported for extended-range VLANs.
(Optional) Configure the VLAN as the RSPAN VLAN. See the
"Configuring a VLAN as an RSPAN VLAN" section on
page
26-16.
Purpose
Display status of VLANs in the VLAN database.
Display status of all or the specified VLAN in the VLAN
database.
