Ports are grouped into broadcast domains by assigning them to the same VLAN. Frames received in one VLAN can only be forwarded within that VLAN, and IP Multicast frames and unknown unicast frames are flooded only to ports in the same VLAN.

Important terms used with the 802.1Q tagging feature are: 302401-D Rev 00 • VLAN identifier (VID) -- the 12-bit portion of the VLAN tag in the frame header that identifies an explicit VLAN. • Port VLAN identifier (PVID) -- a classification mechanism that associates a port with a specific VLAN.
PAGE 60
kombk.book Page 34 Tuesday, June 29, 1999 3:25 PM Using the BayStack 450 10/100/1000 Series Switch • Filtering database identifier (FID) -- the specific filtering/forwarding database within the BayStack 450 switch that is assigned to each VLAN. The current version of software assigns all VLANs to the same FID. This is referred to as Shared VLAN Learning in the IEEE 802.1Q specification.

When connecting multiple switches, it is possible to connect users of one VLAN with users of that same VLAN in another switch. However, the configuration guidelines depend on whether both switches support 802.1Q tagging. With 802.
PAGE 64
kombk.book Page 38 Tuesday, June 29, 1999 3:25 PM Using the BayStack 450 10/100/1000 Series Switch Because there is only one link between the two switches, the Spanning Tree Protocol (STP) treats this configuration as any other switch-to-switch connection. For this configuration to work properly, both switches must support the 802.1Q tagging protocol. VLANS Spanning Multiple Untagged Switches Figure 1-22 shows VLANs spanning multiple untagged switches. In this configuration switch S2 does not support 802.

kombk.book Page 39 Tuesday, June 29, 1999 3:25 PM BayStack 450 10/100/1000 Series Switches To connect multiple VLANs across switches with redundant links, you must disable the STP on all participating switch ports. Figure 1-23 shows possible consequences of enabling the STP when using VLANs between untagged (non-802.1Q tagged) switches.

It is also possible to have resources exist in multiple VLANs on one switch as shown in Figure 1-24. In this example, clients on different broadcast domains share resources.

Each decimal number represents an 8-bit octet. When strung together, the four octets form the 32-bit Internet address. This is called dotted-decimal notation. The largest possible value of a field in a dotted-decimal number is 255, which represents an octet of all ones. 6.

RJ-45 (10BASE-T/100BASE-TX) Port Connectors The RJ-45 port connectors (Figure E-1) are wired as MDI-X ports to connect end stations without using crossover cables. (See “MDI and MDI-X Devices” on page E-2 for information about MDI-X ports.) For 10BASE-T connections, use Category 3 (or higher) UTP cable.

The DSR and CTS signal outputs are always asserted; the CD, DTR, RTS, and RI signal inputs are not used. This configuration enables a management station (a PC or console terminal) to connect directly to the switch using a straight-through cable.
