Configuration Management VLAN Manager (SETTINGS menu > Configuration Management > VLAN Manager) enables easy and dynamic update of VLAN configurations. Through the VLAN Manager, you can add, edit, and delete VLANs from individual devices. You can also take advantage of VLAN Trunking Protocol (VTP) enabled by Cisco switches where updating VLAN properties on one device triggers VLAN database refresh on other devices. Otherwise, you can copy and move single or multiple VLAN specifications from one network device to other VLAN-capable network devices.
Important: Devices in WhatsUp Gold must have proper read/write credentials assigned before you can apply VLAN specification changes. Some switches/routers allow configuration using SNMP, in other cases you will need SSH or Telnet credentials (that enable WhatsUp Gold to run system scripts) to apply VLAN configuration changes.
To manage device VLAN configurations, consider the following:
Note: Cisco VTP-enabled devices run in VTP server mode by default.
To configure device VLANs using the VLAN Manager:
Note: You cannot edit the VLAN Index. If you want to modify a VLAN's index number, you must delete the VLAN and add the VLAN again with the desired index number. You cannot edit VLANs that are reserved by the switch vendor. For example, you cannot use default VLANs or Cisco Reserved VLAN indexes (1000-1024).
Note: You will be prompted before you remove a VLAN from a device.
