Example 2, VLANs Across Multiple Switches
12-28 VLAN Operation and Network Applications
Port 3 is set as follows:
PVID: 2
Acceptable Frame Types: ADMIT ALL FRAMES
Ingress Filtering: ENABLED
GVRP Status: DISABLED
This causes the switch to classify all untagged frames received as belonging to the VLAN
specified by each port PVID and to replace the previous PVID information in the port VLAN
List with the new PVID information. This makes Port 1 part of the Blue VLAN, Port 3 part of
the Red VLAN, and both are set to the VLAN frame format of untagged.
4. Port 2 is configured as a trunk port by setting the Egress type for both VLAN ID 2, Port 2, and
VLAN ID 3, Port 2, to TAGGED using the Static VLAN Egress Configuration screen. This
means that these ports will only transmit tagged VLAN frames.
Egress: Port 2: TAGGED
5. Port 2 is configured as follows using the VLAN Port Configuration screen:
Port 2 is set as follows:
PVID: 1
Acceptable Frame Types: ADMIT TAGGED FRAMES ONLY
Ingress Filtering: ENABLED
GVRP Status: ENABLED
Port 2 is set as a trunk port and all frames forwarded out this port are forwarded as tagged frames.
By default the port remains as a member of the Default VLAN. With the original classification
information inserted in the frame Tag Header, the receiving switch will maintain the original
frame classification. GVRP is enabled on this port and will support dynamic VLANs created by
GVRP. The operation of GVRP is described in Appendix A.
