Features

Management Interface Options

The Catal yst 2900 XL and Ca talys t 3500 XL switches are design ed for
plug-and-play operation : you only need to assign basic IP infor mat ion to the
switch and connect it to the other devices in your network. If you have specific
network need s, you c an configure and mo nitor the switch—on an individual basi s
or as part of a switch cluster—through its various management interfaces.

You can configure and monitor individual switches a nd switch clusters by using
the following interfaces:

• Cluster Management Suite (CMS)—CMS is a graphical user interface that

canbelaunchedfromanywhereinyournetworkthroughawebbrowsersuch
as Netscape Communicator or Microsoft Internet Explorer. CMS is already
installedon the switch, and no additional installation is required. Using CMS,
you can fully configure and monitor a standalone switch, a sp ecific cluster
member, or an entire switch cluster. You can also display n etwork topologies
to gather link information, and display switch images to modify switch- and
port-level settings.

Chapter1 Product Overview

• Command-line Interface (CLI)—TheswitchCLICiscoIOSsoftwareandis

enhanced to support desktop- switc hing featu res. You can full y configure and
monitor the switc h and switch cluster m e mbers from the CLI. You c an access
the CLI either by connecting your management station directly to the s witch
console p ort or by using Telnet from a remote manageme nt station.

• Simple network man ag em en t proto co l (SNM P)—SNMP providesa means to

monitor and control the switch and switch cluster members. You can manage
switch configuration settings, performance, security, and collect statistics by
using SNM P management applications such as CiscoWorks2000 LAN
Management Suite (LM S) and HP OpenView.

You can manage the switch from an SNMP-compatible m anagement station
that is running platforms such as HP Op enView or SunN et Manager. The
switch support s a comp rehensive set of MIB extensions and four Remote
Monitoring (RMON) g roups.

For more information about CM S, the CL I, and SN MP refer to the Catalyst
2900 Ser ies XL and Catalyst 3500 Series XL Soft ware Configuration Guide.

48005

The 10/1 00 switch ports (see Figure 1-2 and Figure 1-4) can connect to any
compatible network d evice up to 328 feet (100 m ete rs) away:

• 10BASE-T-compat ible devices, such as worksta tions, Cisco IP Phones, and

hubs throug h standard RJ-45 c onn ector s and Ca tegory 3, 4, or 5 cabling

• 100BASE-TX-compatible devices, such as high-speed workstations,

Cisco IP Ph ones, se rvers, hub s, ro uter s, and other switches thr oug h stan dard
RJ-45 connectors and Category 5 cabling

10BASE-TcanuseCategory3and4cables.

When connecting the switch to workstations, servers, routers, and Cisco IP
Phones, be sure that the cable is a straight-through, twisted-pair cable. W he n
connecting the switch to switches or hubs, use a crossover c able. Pinouts for
the cab les are desc ribe d in Appendix B, “Connectors and Cable

Specifications.”

The 10/1 00 switch ports can be explici tly set to operate in any combination of
half duplex, full duplex, 10 M bp s, or 100 Mbps. These ports also c an be set for
speed and duplex aut onegotia tion, compliant with IEEE 802.3u. When set for
autonegotiation, the po rt senses the speed and du plex settings of the attached
device and advertises its own capabilities. If the connected device also supports
autonegotiation, the switch port negotiates the best c onne ction (that is, the fastest
line speed that both devices support and full-duplex transmission if the attached
device supports it) a nd configures itself a ccor dingly.

Chapter 1 Product Overview

The 10/100 ports on t he Catalyst 2900 XL switches provide proto col support for
Cisco IP Ph ones and per-port priority override. Refer to the Catalyst 2900 Seri es
XL and Catalyst 3500 Series XL Software C onfiguration Guide for more
information about these featu res.

Cisco IP Phones—conne cte d to the 10/100 port—must be conn ect ed to an AC
power source. Unlike th e 3524-PWR X L switch, the Catalyst 2900 XL switch es
do not provide inli ne power.

For more info on the Catalyst 3524-PWR XL switch , refer to the
Catalyst 3500 Series XL Hardware Installation Guide.

100BASE-FX Ports

The 100BASE-FX ports use 10/125- or 62.5/125-micron multimode fiber-optic
cabling. The connection distances between the switch and the attached device can
be as follows:

100BASE-FX Ports

• If the switch port and the port on the att ache d device are configured for

half-duplex operation, the conn ect ion can be up t o 1352 fe et (412 meters).

• If the switch port and the port on the att ache d device are configured for

full-duplex operation , the connection can be over distanc es of up to 6562 feet
(2 kilometers).

Long-Reach Ethernet Ports

The Long-Reach Ethernet (LRE) ports (Figure 1-4) use one RJ -21 connector to
connect up to 24 Cisco 575 LRE customer premises equipment (CPE ) devices
though unstructure d wi ring , such a s existin g tel epho ne line s. The link between t he
LREswitchportandeachCPEdevicecanreachspeedsofupto15Mbps(full

100BASE-F X Ports

Chapter1 Product Overview

If telephone services, such as voice or i ntegrat ed services digital ne twork (ISDN),
use the same cabling as LRE traffic, the LRE port must be conne cte d to the patc h
panel through a basic telephone service, al so known as pl ain old telephone service
(POTS) splitter. The splitter r outes LRE data (high-frequency) and voice
(low-frequency) traffic from t he telephone line to the switch and private branc h
exchange (PBX) switch or public -switche d telephone network (PSTN)

If the other t el ephon e services are c onnec ted through a private bra nch exchange
(PBX) switch, a Cisco LRE 48 POTS Splitter can b e used. The PBX routes voice
traffic to private telephon e networks a nd the publi c system tele phone network
(PSTN). For more information about the Cisco LRE 48 POTS Splitter
(PS-1M-LRE-48), refer to the Installation Notes for the Cisco LRE 48 POTS
Splitter.

If the installation does not have a PBX, a homologated POTS splitter is required
to directly connect to t he PSTN. For mor e info rmati on about h om ologated POTS
splitters, contact your Cisco sales representative.

Note If a connection to a phone network is not required at all, a splitter is not

needed, and the switch can connect directly to the patch panel.

Expansion Slots

The expansion slots (see Figur e 1-2) a re f or the Cataly st 2900 XL h ot-swappable
modules. Each module port is internally switched to other switch ports and is
managed through the switch managemen t interfaces.

Table 1-1 lists the modules that the expansion slots support.

Modules W S-X29 14-XL and WS- X292 2-XL support 2048 MAC addre sses. If
you install one of these m odules in a 2924M XL or Cata lyst 2912MF X L switch
(both supporting 8192 MAC add resses ), the module fails POST. You can start the
module by restarting the switch with the module installed. After the restart, the
switch address capacity is reduced to 2048 MAC addresses.

See the Catalyst 2 900 Series XL Modules Installation Guide and the
Catalyst 2900 Series XL ATM Mo dule s Ins talla tion an d Con figuration G uide for
detailed information on expansion modu les for Catal yst 2900 series XL switches.

You can use the switch LEDs to monitor switch activity and its performance.

All of the LED s described in t his section except the utilizat ion meter (UTL) are
visible on the Clust er Management Suite (CMS) window and, if the switch is a
cluster member, on the CMS Cluster Manager window. The Ca talyst 2900 Series
XL and Catalyst 3500 Series XL Software Configuration Guide describe s how to
