CHAPTER 10: VLAN VLAN

10.4.3 Example

In the following example, we start with Port VLAN and convert to TAG VLAN. We define ports 3 through 5 to belong to VLANs 10, 20 and 30 and the rest of the ports belong to the default VLAN (in this case, VLAN 1). Filtering is enabled on ports 3 to 5. The VLAN setup is done before devices are plugged into ports 3 to 5 as a result the status of the ports show the port status as DOWN.

1.A word of caution - when Tag VLAN filtering is enabled, there can be serious connectivity repercussions - the only way to recover from that it is to reload the switch without saving the configuration or by modifying the configuration from the console (serial) port.

2.There can be either Tag VLAN or Port VLAN. Both VLANs cannot co-exit at the same time.

3.There can only be one default VLAN for the switch. The default is set to VLAN 1 and can be changed to another VLAN. A word of caution on changing the default VLAN as well - there can be repercussions on management as well as multicast and other issues.

4.Tag VLAN support VLAN ids from 1 to 4096. VLAN ids more than 2048 are reserved for specific purposes and it is recommended they not be used.
