Introduction
The CheetahSwitch Workgroup-3726M is perfect for moving workgroups from
conventional 10 Mbps Ethernet to multiple-segment 100 Mbps Fast Ethernet, and
for consolidating your network equipment into a single, clean, efficient, and
super-fast switch stack. This switch system delivers dedicated 100 Mbps links to
each attached LAN segment (independent collision domain) or to any PC attached
directly to the stack – all with conventional cabling and adapters. It completely
eliminates the bottlenecks of shared 10 Mbps Ethernet networks by providing a wide
bandwidth of up to 8.8 Gbps per switch, and a stack backplane that can operate at
up to 9.6 Gbps. This makes it ideal for increasing the throughput of interconnected
Ethernet and Fast Ethernet hubs or server farms.
This switch includes three slots on the rear panel for various modules:
• The upper slot is for an SNMP/RMON Management Module. The stack supports only
one management agent.
• The lower right slot is for optional media expansion modules, including a dual-port
100 Mbps fiber optic module that can be connected to a remote site up to
2 kilometers (1.24 miles) away, or a single-port Gigabit module that can be used to
uplink to a collapsed Gigabit backbone or for a high-speed server connection.
• The lower left slot is for either an optional media expansion module or Stacking
Module. (Up to four switch units can be stacked together using Stacking Modules.)
When the Management Module is installed, this system can provide a wide array of
advanced features:
• Master agent module manages entire stack in-band or out-of-band
• Backup agent module provides fault tolerance*
• Supports Telnet, SNMP/RMON and Web-based interface
• Four-group RMON (including Statistics, History, Alarms and Events)
• Spanning Tree Algorithm for redundant paths between switches
• VLAN support for up to 256 groups, port-based or with 802.1Q VLAN tagging
• GVRP for automatic VLAN learning*
• IGMP multicast filtering
• Quality of Service supports two levels of priority with Weighted Fair Queueing
• Configurable broadcast storm control
• Port mirroring (for real-time debugging without affecting the target port)
• Port trunking (up to 5 trunks per switch or 12 trunks for the entire stack, each trunk
contains 2~4 ports)
* This feature is not supported in the current firmware release.
The agent module allows you to configure or monitor the switch using the embedded
management program or SNMP/RMON applications. To manage the switch, you can
make a direct connection to the console port. You can also make a network
connection to manage the switch using Telnet, the Web agent, or Accton’s free
Windows-based network management software called AccView/Open.
