Cisco Catalyst 3000

The Cisco Catalyst 3000 has a completely different architecture than any other Cisco switch. However, this series of switches received an End−of−Life (EOL) notice from Cisco, so we will include only a basic overview in this chapter.

∙The Catalyst 3000 series provides the following features:

∙Stacked switch platforms that are manageable as if they were a single logical entity. These switches automatically configure themselves as new switches are added or removed.

∙Cut−through switching technology delivering wire−speed, low−latency switching. The Catalyst 3000 also has the ability to use FragmentFree or Runtless switching, which automatically changes to store−and−forward when an error rate has been exceeded.

∙Optional modules to provide additional interfaces for more Ethernet ports, Fast Ethernet ports, ATM ports, and WAN connectivity.

∙User definable per−port and secure−mode filtering that provides access control for sensitive information resources.

∙Support for up to 64 VLANs using Cisco’s LAN Emulation (LANE)−based ATM, and ISL−based Fast Ethernet VLANs to extend switched VLANs throughout the enterprise.

∙Spanning−Tree Protocol (STP) implemented by VLAN for loop detection.

∙An optional stack port interface module that connects one 3000 series switch to another. This Catalyst Matrix delivers 280Mbps per switch of bandwidth for unrestricted traffic flow.

Some of the basic hardware features of the Cisco Catalyst 3000 series of switches are listed in Table E.5.

Cisco Catalyst 3500 Series XL

The Cisco Systems Catalyst 3500 series XL is a scalable line of stackable 10/100 and Gigabit Ethernet switches. These switches provide high performance and investment protection for companies that are expanding their switched networks. The three major applications for the 3500 series XL are as follows:

∙In the enterprise wiring closet at the enterprise edge, aggregated to a larger Catalyst switch

∙In a branch office where it can provide a LAN backbone and desktop connectivity

∙In a multilayer network where it can be deployed with a Layer 3 switch for a low cost solution

Each Catalyst 3500 XL comes with 2 Gigabit Ethernet interfaces that come with 12, 24, or 48 Gigabit Interface Converter (GBIC) ports and auto−sensing 10BaseT/100BaseTX ports. The 3508G XL provides eight
