. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-9 Feature Summaries The following summaries provide a brief description of the switch features in areas such as standards compliance, functionality, performance, and options. IEEE 802.1D Bridge The Compaq switch is fully compliant with IEEE 802.1D transparent bridging specifications. An aggregate address table containing 4096 entries per 8 switch ports is provided for learning, filtering, and forwarding.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-10 Overview Frame Buffering and Frame Latency The switch is a store-and-forward switching device. Each frame is copied into switch memory before being forwarded to another port. This method ensures that all forwarded frames conform to a standard Ethernet frame size and have a correct cyclic redundancy check (CRC) for data integrity.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-11 Configuration and Management Interfaces The switch can be managed using any of the following three methods: n Serial console, out-of-band An RS-232 connection, using a DB-9 connector with null modem cable, is supported for out-of-band switch management. Serial console management is performed using a terminal, or computer system running communications software.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-12 Overview RMON RMON (Remote Monitoring) is a facility used to manage networks remotely while providing multi-vendor interoperability between monitoring devices and management stations. An SNMP MIB defines RMON. This MIB is divided into nine different groups, each gathering specific statistical information or performing a specific function.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-13 Auto-negotiation Auto-negotiation is a process that permits the switch to automatically select the operational modes of its ports. Upon first being connected, the switch detects the speed of the connected network to the port, either 10Mb/s or 100Mb/s. In addition, the switch detects the type of communication setting, half or full duplex. The port is then automatically set by the switch to operate in the proper mode, without user intervention.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-14 Overview LEDs The port LEDs on the switch provide a quick and accurate display of the integrity of switch connections and switch mode. The operation of the RJ-45 port LEDs can be changed by use of the LED mode button on the switch front panel. The LED mode button does not affect the operation of the fiber port LEDs. The default operation of the RJ-45 LEDs indicates Link (L) and Activity (A) for each of the ports.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-15 Class of Service Class of Service support allows you to assign a higher priority to selected traffic passing through the switch. The switches support Class of Service attributes per the IEEE802.1D/D5 (previously known as IEEE 802.1p) standard specification using a priority queuing mechanism. This feature ensures that traffic during congestion periods will not interfere with traffic assigned a higher priority.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-16 Overview Figure 1-5 Client/Server Network Application Local Backbone Application The switch can be used in a local backbone application, connecting network segments together and providing file-server access (Figure 1-6). Workgroup hubs are provided with a single connection to the switch while servers are put on dedicated 100 Mb/s ports. Routers and other networking devices can connect off of the switched backbone as well.

This capability provides a highly efficient architecture for establishing VLANs within a network and for controlling broadcast/multicast traffic between workgroups. Central to this capability is an explicit frame tagging approach for carrying VLAN information across interconnected network devices.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . C-2 Virtual Lans (VLANs) If the switch is so configured, a unique VLAN identifier is placed in a tag appended to the packet when it is received by the switch from end-station nodes, if the packet does not already contain this information. The tag is then stripped off when the packets are forwarded to the destination end stations. Within the switch and between switches compliant with IEEE 802.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . C-3 VLAN Hybrid Ports A VLAN hybrid port is used to connect one or more VLAN-aware or VLANunaware devices attached to it. Both tagged and untagged frames can be transmitted on hybrid ports. In example 1 in Figure C-3A, two different VLANs are configured as X and Y. A packet arrives (1) with a tag for VLAN Z, goes straight through the switch (2) and back out (3), destined for VLAN Z, a VLAN Z-aware end-user workstation.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . C-4 Virtual Lans (VLANs) In example 3 in Figure C-3B, an untagged frame arrives at the left side port (1). The frame is tagged with a VLAN X tag (2), and comes out Port Y with a VLAN X tag (3). The ultimate destination of the frame may be on the outgoing port’s segment or on another segment. Example 4 in Figure C-3B, is similar to Example 3 except that both ports (incoming and outgoing) are on VLAN X.

( %TTIRHM\ ( 'PEWW SJ 7IVZMGI Class of Service support allows you to assign mission-critical data a higher priority through the switch by delaying less critical traffic during periods of congestion. Higher priority traffic through the switch is serviced first before lower priority traffic. The Class of Service capability of the SW3322/SW3323/SW3324 switch is implemented by a priority queuing mechanism.
