Chapter 7 Features of LAN-Based Switching Technologies
Catalyst 3524-PWR XL Switch
• 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.
