1. Introduction
1-1. Overview of 8+1 Managed Ethernet Switch
8+1 MANAGED ETHERNET SWITCH, implemented 8 10/100Mbps TP+ 1
module slot supporting Gigabit and Fast Ethernet modules, is a standard switch that
meets all IEEE 802.3/u/x/z Gigabit, Fast Ethernet and Ethernet specifications. The
switch can be managed through RS-232 serial port via directly connection, or
through Ethernet port using Telnet or Web-based management unit, associated with
SNMP agent. With the SNMP agent, the network administrator can logon the switch
to monitor, configure and control each port’s activity in a friendly way. The overall
network management is enhanced and the network efficiency is also improved to
accommodate high bandwidth applications. In addition, 8+1 MANAGED
ETHERNET SWITCH features comprehensive and useful function such as QoS
(Quality of Service), Spanning Tree, VLAN, Port Trunking, Port Security,
SNMP/RMON and IGMP Snooping capability, Failover and Illegal Access Report via
the intelligent software. It is suitable for both metro-LAN and office application.
• Key Features in the Device
QoS:
Support Quality of Service by the IEEE 802.1P standard. There are two
priority queue and packet transmission schedule using Weighted Round
Robin (WRR). User-defined weight classification of packet priority can be
based on Either a VLAN tag on packet or a user-defined port priority
Spanning Tree:
Support IEEE 802.1D, IEEE 802.1w (RSTP: Rapid Spanning Tree
Protocol) and IEEE 802.1s (MSTP: Multiple Spanning Tree Protocol)
standards.
VLAN:
Support Port-based VLAN, IEEE802.1Q Tag VLAN and IEEE802.1v
Protocol-based VLAN. Support 64 active VLANs and VLAN ID 1~4094.
Port Trunking:
Support static port trunking and port trunking with IEEE 802.3ad LACP.
Port Security:
Support allowed, denied forwarding and port security with MAC address.
SNMP/RMON
SNMP Agent: MIB-2 (RFC 1213)
Bridge MIB (RFC 1493)
RMON MIB (RFC 1757)-statistics Group 1,2,3,9
VLAN MIB (802.1Q)

IGMP Snooping:
Support IGMP version 2 (RFC 2236): The function IGMP snooping is used
to establish the multicast groups to forward the multicast packet to the
member ports, and, in nature, avoid wasting the bandwidth while IP
multicast packets are running over the network.
Failover:
Support failover function to provide a backup link for an existed link. This
function is different from Link Aggregation (Trunking) and LACP. 8+1
MANAGED ETHERNET SWITCH provides up to 2 failover pairs.
Illegal Access Report:
Support Illegal Access Report function to display the unauthorized users
accessing the switch. If Allowed forwarding or Denied forwarding was
configured, Illegal Access Report starts recording which illegal user(s) try to
access.
There is one slot used for high-speed connection expansion; six optional
module types provided for the switch are listed below:
10/100/1000Base-T Gigabit Copper Module
1000Base-SX Gigabit Fiber Module
1000Base-LX/LHX/XD/ZX Gigabit Fiber Module, up to 70Km
100Base-FX 100Mbps Fiber Module, up to 100Km
100Base-FX Single Fiber WDM Module
1000Base-LX Single Fiber WDM Module
10/100/1000Base-T Gigabit Copper Module fully complies with IEEE
802.3/u/x/z Gigabit, Fast Ethernet specifications. 1000Base-SX/LX/LHX/XD/ZX
Gigabit Fiber Module is a Gigabit Ethernet port that fully complies with all IEEE
802.3z and 1000Base-SX/LX/LHX/XD/ZX standards. 100Base-FX Fiber Module is a
100Mbps Ethernet port that fully complies with all IEEE 802.3u and 100Base-FX
standards.
100Base-FX/1000Base-LX Single Fiber WDM Module is designed with an
optic Wavelength Division Multiplexing (WDM) technology that transports bi-
directional full duplex signal over a single-strand fiber.
For upgrading firmware, please refer to the Section 4-6 or Section 5-6 for
more details. The switch will not stop operating while upgrading firmware and after
that, the configuration keeps unchanged.

1-3. Features
The 8+1 MANAGED ETHERNET SWITCH, a standalone off-the-shelf switch,
provides the comprehensive features listed below for users to perform system
network administration and efficiently and securely serve your network.
Management
• Port Status, Counter and Configuration.
• Display the basic System Information on user interface.
• System configuration which includes administrator, guest users and IP address
relative to parameters and SNMP basic parameters.
• Maximal packet length can be up to 1536 bytes.
• Support Broadcasting Suppression to avoid power lost and recovery while a
bunch of converter boxes register to NMS simultaneously.
• The trap events/alarm can be sent via e-mail and mobile phone short message.
• A configured setting can be saved into the on-board flash memory. And the
current setting can be recovered from the default setting or the previous
configured setting via Restore User Configuration.
• On-board diagnostics function can let administrator know the hardware status.
• On-board firmware can be updated via TFTP function.
• The Advanced Managed Ethernet Switch allows administrator to reboot system
from management station.
• The Advanced Managed Ethernet Switch will log the last 60 records in the main
memory and display on the local console. And the converter will send out the
record message while fiber connection recovered.
