Chapter 13 Configuring VLANs
Configuring Normal-Range VLANs
Caution
You can cause inconsistency in the VLAN database if you attempt to manually delete the vlan.dat file.
If you want to modify the VLAN configuration, use the commands described in these sections and in the
command reference for this release. To change the VTP configuration, see
Chapter 14, “Configuring
VTP.”
You use the interface configuration mode to define the port membership mode and to add and remove
ports from VLANs. The results of these commands are written to the running-configuration file, and you
can display the file by entering the
show running-config privileged EXEC command.
You can set these parameters when you create a new normal-range VLAN or modify an existing VLAN
in the VLAN database:
•
VLAN ID
• VLAN name
•
VLAN type (Ethernet, Fiber Distributed Data Interface [FDDI], FDDI network entity title [NET],
TrBRF, or TrCRF, Token Ring, Token Ring-Net)
• VLAN state (active or suspended)
•
Maximum transmission unit (MTU) for the VLAN
• Security Association Identifier (SAID)
•
Bridge identification number for TrBRF VLANs
• Ring number for FDDI and TrCRF VLANs
•
Parent VLAN number for TrCRF VLANs
• Spanning Tree Protocol (STP) type for TrCRF VLANs
•
VLAN number to use when translating from one VLAN type to another
Note
This section does not provide configuration details for most of these parameters. For complete
information on the commands and parameters that control VLAN configuration, see the command
reference for this release.
These sections contain normal-range VLAN configuration information:
• Token Ring VLANs, page 13-6
•
Normal-Range VLAN Configuration Guidelines, page 13-6
• Configuring Normal-Range VLANs, page 13-7
•
The configurations of VLAN IDs 1 to 1005 are always saved in the VLAN database (vlan.dat file).
If the VTP mode is transparent, they are also saved in the switch running configuration file. You can
enter the copy running-config startup-config privileged EXEC command to save the configuration
in the startup configuration file. In a switch stack, the whole stack uses the same vlan.dat file and
running configuration. To display the VLAN configuration, enter the show vlan privileged EXEC
command., page 13-7
