Using the BayStack 303 and 304 Ethernet Switches

1-2

893-01010-A

Multiple switches can be connected to one another (or to other 802.1D bridges/
switches/hubs) to form a switched/segmented (or bridged) Ethernet backbone.

Key features of the BayStack 303 and 304 Ethernet Switches are:

•

Provides 10 Mb/s and 100 Mb/s switching in the following configurations:

— 12 (BayStack 304) or 24 (BayStack 303) 10BASE-T half-duplex ports 

with standard RJ-45 connections

— One 10/100BASE-TX half- or full-duplex autonegotiating port

— Addition of an optional 10/100BASE-TX half- or full-duplex 

autonegotiating copper port or 100BASE-FX fiber port

•

Supports IEEE 802.3u autonegotiation standard on 10/100BASE-TX ports

•

Supports up to 1024 media access control (MAC) addresses per switch

•

Provides store-and-forward switching mode

•

Provides significant aggregate throughput for all packet sizes, including the 
minimum size (64 bytes) Ethernet frame:

— 420,000 packets per second (pps) for BayStack 304 Ethernet Switch

— 380,000 pps for the BayStack 303 Ethernet switch

•

Supports IEEE 802.1d Spanning Tree Protocol on each port to provide 
automatic network configuration of a loop-free topology and redundant 
inter-switch links

•

Supports broadcast and multicast traffic control

•

Provides user interface that supports international languages: English, 
German, French, Italian, Spanish, Japanese, and Chinese

•

Supports in-band Telnet connections through any port

•

Provides SNMP (Simple Network Management Protocol) manageability 
through any port; supports MIB II and Bridge MIB

•

Supports Groups 1, 2, 3, and 9 RMON

•

Supports TFTP remote software image download

•

Provides indicators for power, system, and port operation
