VLAN Switch Operation

Figure 12-2depicts the inside of a switch with six ports, numbered one through six. The switch has been configured to associate VLAN A and B with Filtering Database Identifier (FDB ID) 2, VLAN C and D with FDB ID 3, and VLAN E with FDB ID 4. Port 6 has been classified to serve as a VLAN trunk connection (will only transmit and receive tagged frames). This classification establishes that all VLANs are members of the Port VLAN List for Port 6 and the frames transmitted for all VLANs will contain a tag header. Also the PVID for Port 6 is set to the default VLAN with its corresponding relationship to FDB ID 1. Although untagged frames are not usually present on a VLAN trunk connection, any untagged frames received would need to be classified if the port has not been configured to drop all untagged frames.

NOTE: The example in Figure 12-2shows ports sharing the same FDB ID, which is supported by the switch. However, this feature cannot be configured using Local Management at this time, but it can be configured using an SNMP management application.
