Stackable NWay Ethernet Switch User’s Guide
Introduction 13
♦
One slide-in module interface in the front panel for 1 or 2 ports 10/100M Ethernet connection. Three
optional modules are available: 2-port TX, 2-port FX (MT-RJ), and 1-port FX (SC).
♦
Stacking Input/Output port slide-in module in the rear panel for stacking to another device to
implement a high-port count, manageable switch. Three-port module for master device and one-port
module for a client device.
Performance features
♦
Store and forward switching scheme capability to support rate adaptation and protocol conversion.
♦
Full- and half-duplex for 10Mbps and 100Mbps connections. The optional 1000BASE-SX and
1000BASE-LX modules operate at full-duplex only. The optional 1000BASE-T module, however, can be
negotiated to 1000M/half.
♦
Auto polarity detection and correction of incorrect polarity on the receive twisted pair at each port.
♦
Data forwarding rate 14,880 pps per port at 100% of wire-speed for 10Mbps speed.
♦
Data forwarding rate 148,800 pps per port at 100% of wire-speed for 100Mbps speed.
♦
Data forwarding rate 1,488,100 pps per port at 100% of wire-speed for 1000Mbps speed.
♦
Data filtering rate eliminates all error packets, runts, etc. at 14,880 pps per port at 100% of wire-speed
for 10Mbps speed.
♦
Data filtering rate eliminates all error packets, runts, etc. at 148,800 pps per port at 100% of wire-speed
for 100Mbps speed.
♦
Data filtering rate eliminates all error packets, runts, etc. at 1,488,100 pps per port at 100% of wire-
speed for 1000Mbps speed.
♦
12K active MAC address entry table per device with automatic learning and aging (10 to 9999 seconds).
♦
12 MB packet buffer per device.
♦
Supports Broadcast Storm filtering.
♦
Supports IGMP Multicast snooping.
Management
♦
RS-232 console port for out-of-band network management via a console terminal or PC.
♦
Spanning Tree Algorithm Protocol for creation of alternative backup paths and prevention of indefinite
network loops.
♦
Fully configurable either in-band or out-of-band control via SNMP based software.
♦
Flash memory for software upgrade. This can be done in-band via BOOTP/TFTP. Out-of-band console
can also initiate a download request.
♦
Built-in SNMP management: Bridge MIB (RFC 1493), RMON MIB (RFC 1757), and MIB-II (RFC 1213).
