This chapter provides information on the FastHub 300 series hubs, which include the FastHub 316T and the FastHub 316C. The information is organized into the following sections:
The Cisco FastHub 300 series of 100BaseT hubs combines all the benefits of stackable hubs with unmatched configuration flexibility, affordability and integrated Cisco IOS technologies. These modular, Class II repeaters deliver 10 times the performance of 10BaseT hubs and provide a choice of modules for a combination of cost-effective 10BaseT and 100BaseT bridging, integrated management and port expansion for a highly scalable, manageable, and resilient solution.
The FastHub 300 series hubs are ideal high-performance alternatives to 10BaseT hubs, delivering affordable 100-Mbps performance to workgroups and server farms. The FastHub 316T comes equipped with 16 100BaseTX ports for connecting your workstations and servers with inexpensive UTP wiring. The FastHub 316C has 15 100BaseTX ports and one100BaseFX port for linking UTP devices to a fiber Fast Ethernet backbone.
Both hubs expand easily to 32 ports within a single unit by simply installing a 100BaseTX/16 port module in an expansion slot. The module is hot-swappable, so you can add users without powering down the network and disrupting existing users. Up to four fully configured FastHub 300 series hubs can be interconnected using a hub expansion cable to create a single, 128-port logical repeater. For the ultimate in expandability, the hub's unique Class II design lets you connect two of these 128-port stacks directly together in a single collision domain. The design also lets you distribute and connect hubs and hub stacks in separate wiring closets without requiring an intermediate switch, bridge, or router.
Each FastHub also has a second expansion slot for a hot-swappable bridge management module (BMM) or network management module (NMM). The BMM provides affordable connectivity to 10BaseT environments, extended cabling distances in 100BaseT networks, and integrated management in a single, flexible solution. The NMM delivers integrated management on a per-port, per-hub, and per-stack basis.
A single NMM or BMM is all that is needed to manage an entire FastHub 300 series stack. Both modules deliver Simple Network Management Protocol (SNMP), Telnet, and Remote Monitoring (RMON). An out-of-band management console is supported for comprehensive management and simplified troubleshooting. An extensive array of mode-selectable LEDs offers a convenient visual display of each port's status and the overall traffic load.

- Cisco's FastHub 300 series Bridge Management Module (BMM) provides affordable connectivity to 10BaseT environments, extended cabling distances and integrated management in a single, flexible solution.
- One bridged 10BaseT port provides a bridged connection from 100BaseT to 10BaseT environments allowing network configuration flexibility and preserving investment in 10BaseT equipment.
- One bridged 100BaseT port, 100BaseTX or 100BaseFX, provides a dedicated full-duplex 100 Mbps connection for high-performance LAN connectivity over extended cabling distances
- Full- and half-duplex auto-negotiation detects the speed of the attached device and automatically configures the port without administrator intervention.
- Spanning Tree Protocol support allows for redundancy between the 10BaseT port and the 100BaseT port in case the primary connection fails.
- Per-port broadcast storm control prevents faulty end stations from degrading overall systems performance.
- Back-pressure flow control on 10BaseT half-duplex connection prevents packet loss
- Network management module (NMM) for comprehensive management and simplified trouble shooting on a per-port, per-hub, and per-stack basis
- 16-port 100BaseTX expansion module for up to 32 ports in a single unit.
- A single BMM or NMM can manage an entire FastHub 300 series stack, lowering cost and providing simplified management

- Cisco Discovery Protocol (CDP) enables a CiscoViewTM network management station to automatically discover the hub in a network topology
- Cisco Group Management Protocol (CGMP) and multicast address packet filtering enable the BBM's bridged ports to selectively forward routed IP multicast traffic, reducing overall network traffic
- Works with Cisco 600-Watt RPS to ensure maximum uptime
Part of the Cisco Fast Ethernet line of products, which includes switches, routers, and hubs
- Incorporates Cisco IOSTM technologies for guaranteed interoperability and integrated and consistent management across Cisco's small- to medium-sized business and CiscoFusion solutions.
The FastHub 300 series supports the following applications:
A FastHub 300 series repeater can be used to create a high-performance network while preserving investment in 10BaseT equipment. A FastHub 300 base unit configured with an expansion module will support a total of 32 100BaseT users or servers. The BMM's 10BaseT and 100BaseT bridging functionality provides connectivity to a legacy 10BaseT hub and a direct connection from the hub to a 100BaseT-enabled switch or router.
A network can be designed using FastHub 300 series repeaters to deliver 100-Mbps throughput for high-performance data transfers for workgroups and server farms over an extended distance. Two BMM-enabled FastHub repeaters (or FastHub stacks) can be used to interconnect 100BaseT workgroups and server farms when wiring closets are further apart than the allowable distance defined by the Class II repeater design guideline.
FastHub 300 series hubs or stacks can connect workgroups and server farms to a campus backbone at a distance of up to 2 kilometers. FastHub 300 series hubs or stacks each with a BMM-100BaseFX can be located up to 2 kilometers from the corporate backbone cabling.
