Features of LAN-Based Switching Technologies


Cisco Catalyst switches allow full integration of voice, video, and data applications in the Cisco ICS 7750 system. The Cisco ICS 7750 system can include the following switches:

Catalyst 3524-PWR XL Switch

Catalyst 4000 Switches

Catalyst 6000 Switches

The Catalyst 3524-PWR XL switch and Catalyst 4000 switches allow LANs to fully integrate voice, video, and data applications. Catalyst 6000 switches are primarily for enterprise and service provider environments.

Catalyst 3524-PWR XL Switch

The Catalyst 3524-PWR XL switch was developed for use with the Cisco ICS 7750 to allow full integration of voice, video, and data applications. The Catalyst 3524-PWR XL switch has 24 10/100 switched ports with integrated inline power, which provides DC current to devices that can accept power over unshielded twisted pair (UTP) cabling, such as the Cisco 7900 family of IP phones. The Catalyst 3524-PWR XL switch also has two Gigabit Interface Converter (GBIC)-based Gigabit Ethernet ports, which support one full-duplex link (in a point-to-point configuration) or up to nine half-duplex links (in a stack configuration) to other Gigabit Ethernet devices. Figure 7-1 shows the front panel of the Catalyst 3524-PWR XL switch.

Key Features

The Catalyst 3524-PWR XL switch has the following key features:

24 autosensing 10/100 Ethernet ports: full-duplex operation delivering up to 200 Mbps.

Two fixed GBIC-based Gigabit Ethernet ports: full-duplex operation delivering up to 2 Gbps, supports one full-duplex link (in a point-to-point configuration) or nine half-duplex links (in a stack configuration).

IEEE 802.1p support: dual-priority forwarding queues on each 10/100 and Gigabit Ethernet port, enabling network traffic prioritization and seamless data, voice, and video integration.

Bandwidth aggregation through Fast EtherChannel and Gigabit EtherChannel technologies, offering from 400 Mbps to Gbps of aggregated bandwidth between switches, to routers, and to individual servers.

Cisco Inter Switch Link (ISL) and IEEE 802.1Q trunking support on all ports: supports automatic segmentation of phone and data endpoints into separate logical networks.

Supports 8192 Media Access Control (MAC) addresses.

IEEE 802.3z compliance and support for Cisco GBIC modules:

GigaStack GBIC: for creating a 1-Gbps stack configuration of up to nine Catalyst 3500 XL switches; the maximum distance for a GigaStack GBIC-to-GigaStack GBIC connection is 1 m.

1000BASE-SX GBIC module: for fiber connections of up to 550 m.

1000BASE-LX/LH GBIC module: for fiber connections of up to 10 km.

1000BASE-ZX GBIC module: for fiber connections of up to 100 km.

Cisco Group Management Protocol (CGMP) enables a switch to selectively and dynamically forward routed IP multicast traffic to targeted multimedia end stations, reducing overall network traffic.

Cisco IOS command-line interface (CLI) support provides a common user interface and command set through the console port or Telnet.

CiscoView device-management application support.

Cluster Management Suite support: a web-based tool for managing switch clusters or an individual switch through a single IP address.

Simple Network Management Protocol (SNMP) support for in-band management.

Power redundancy: supports an optional Cisco RPS 300 that operates on AC input and supplies DC output.

Inline power

Can provide inline power for Cisco IP phones from all 24 10/100 Ethernet ports.

Autodetection and control of inline phone power on a per-port basis on all 10/100 ports.

Support for fan-fault and over-temperature detection through Cluster Management Suite (CMS).
