Cisco Systems 3560 Manual De Usuario

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 

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

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.
