Page 133: Appendix E. Introduction To Virtual Lans (Vlans)
How VLANs provide extra security Devices within each VLAN can communicate only with devices in the same VLAN. Figure 75 on page 118 shows a network configured with three VLANs—one for each of the departments that access the network. © Copyright IBM Corp. 1999...

0 to 3 are transmitted as low priority. Frames with a priority of 4 to 7 are transmitted at high priority. The mapping from user priority to traffic class is defined in table 7-2 of the IEEE P802.1D standard 8275-416 User’s Guide...
Page 135: Overview Of Ieee 820.1Q Vlan Support
Overview of IEEE 820.1Q VLAN support The switch supports IEEE 802.1Q standards-based VLANs. This standard describes port-based VLANs as well as the methods to propagate VLAN memberships across compliant devices using GARP VLAN Registration Protocol (GVRP). Each frame contains information about the VLAN. This information is contained in a 4-byte tag that is inserted into each frame.
Page 136: Configuration Examples
VLAN. After this configuration is complete, the frames from Station A will arrive at Port 1 untagged, and will then be tagged internally to the switch with the PVID (VLAN 5). 8275-416 User’s Guide...
Page 137 These frames will be sent to port 12 which is a member of the same VLAN. Because the port is set to untagged frames for this VLAN, the tag will be removed and the frame sent to Device B untagged. 802.1Q-compliant device (tagging and GVRP) to 802.1Q- compliant device (tagging and GVRP) No Static VLANs...
Page 138 VLAN. If any devices on a link cannot handle tagged frames, it would be best to configure the port to transmit frames as untagged in any VLAN in which those devices participate. 8275-416 User’s Guide...
Page 139: Using Unique Mac Addresses
Too many duplicate VLANs may also lead to an oversubscription of switch resources. The 8275-416 always guarantees resources for all 32 ports in the Default VLAN (VLAN 1). Up to 31 additional VLANs may be configured or registered with the switch, with certain restrictions.
Page 140 VLANs, but the VLANs having the same port membership. Another use for duplicate VLAN configurations would be if a switch is placed in the core or in an intermediate level of a network. The 8275-416 functions best as an edge device as opposed to as a core switch.
