Cisco administrators can use the VLAN Management Policy Server (VMPS) service to set up a database of MAC addresses that can then be used for the dynamic addressing of VLANs.

Any VLAN numbers above that are called extended VLANs and won’t be saved in the database unless your switch is set to VTP Transparent mode. You won’t see these VLAN numbers used too often in production. Here’s a demonstration of setting my S1 switch to VLAN 4000 when my switch is set to VTP Server mode (the default VTP mode): S1#config t S1(config)#vlan 4000 S1(config-vlan)#^Z % Failed to create VLANs 4000 Extended VLAN(s) not allowed in current VTP mode. %Failed to commit extended VLAN(s) changes.
