10.5 Configuring Tag VLANs with EnerVista Secure Web Management software

10.5.1 Description

When multiple switches are on a network, the VLAN information needs to be propagated on to other switches. In such situations, it is best to use tag based VLANs.

On the ML1200, the port VLAN type is set to none. To use Tag VLANs, first enable Tag

VLANs.

In the following example, we assign various ports as VLANs 10, 20 and 30 and the remaining ports to the default VLAN (that is, VLAN 1).

The VLAN setup occurs before devices are connected to the ports. As such, the port status is shown as DOWN.

There can be serious connectivity repercussions when Tag VLAN filtering is enabled. The only way to recover from this it is to reload the switch without saving the configuration or by modifying the configuration from the console (serial) port.

The ML1200 can be configured for either Tag VLAN or Port VLAN. Both VLANs cannot co- exit at the same time. There can only be one default VLAN for the switch. The default is set to VLAN 1 and can be changed to another VLAN.

There can be repercussions on management as well as multicast and other issues when changing the default VLAN.

Tag VLAN supports VLAN IDs from 1 to 4096. VLAN IDs greater than 2048 are reserved for specific purposes. As such, it is recommended they not be used.

To use the Tag VLAN, first

ZSet the VLAN type to Tag in the Configuration > VLAN > Set Type menu.
