Feature
Benefit
• 4000 VLAN IDs are supported.
• Voice VLAN simplifies telephony installations by keeping voice traffic on a separate VLAN for easier
administration and troubleshooting.
• Cisco VLAN Trunking Protocol (VTP) supports dynamic VLANs and dynamic trunk configuration across
all switches.
• Cisco Group Management Protocol server functions allow a switch to serve as the Cisco Group
Management Protocol router for client switches. The IP Services Image is required.
• IGMP snooping provides fast client joins and leaves of multicast streams and limits bandwidth-intensive
video traffic to only the requestors.
• Remote Switch Port Analyzer (RSPAN) allows administrators to remotely monitor ports in a Layer 2 switch
network from any other switch in the same network.
• For enhanced traffic management, monitoring, and analysis, the Embedded Remote Monitoring (RMON)
software agent supports 4 RMON groups (history, statistics, alarms, and events).
• Layer 2 traceroute eases troubleshooting by identifying the physical path that a packet takes from source to
destination.
• All 9 RMON groups are supported through a SPAN port, which permits traffic monitoring of a single port, a
group of ports, or the entire stack from a single network analyzer or RMON probe.
• Domain Name System (DNS) provides IP-address resolution with user-defined device names.
• Trivial File Transfer Protocol (TFTP) reduces the cost of administering software upgrades by downloading
from a centralized location.
• Network Timing Protocol (NTP) provides an accurate and consistent timestamp to all intranet switches.
• Multifunction LEDs per port for port status; half-duplex and full-duplex mode; and 10BASE-T, 100BASE-TX,
and 1000BASE-T indication as well as switch-level status LEDs for system, redundant-power supply, and
bandwidth utilization provide a comprehensive and convenient visual management system.
• SPAN works across all the ports in a stack.
Cisco Network
Assistant Software
• Cisco Network Assistant Software provides an easy-to-use, Web-based management interface through a
standard Web browser.
• Simplified port configuration via Cisco Smartports.
• Cisco AVVID (Architecture for Voice, Video and Integrated Data) wizards need just a few user inputs to
automatically configure the switch to optimally manage different types of traffic: voice, video, multicast, and
high-priority data.
• A security wizard is provided to restrict unauthorized access to applications, servers, and networks.
• Cisco Network Assistant Software allows management of up to 16 interconnected Cisco Catalyst 3750,
Catalyst 3550, Catalyst 3500 XL, Catalyst 2950, Catalyst 2950 LRE, Catalyst 2900 XL, Catalyst 2900 LRE
XL, and Catalyst 1900 series switches through a single IP address, without the limitation of being physically
located in the same wiring closet. Full backward compatibility helps ensure any combination of these
switches can be managed with a Cisco Catalyst 3750 Series Switch.
• The cluster software upgrade feature allows 1-click software upgrade across an entire cluster of Cisco
Catalyst 3750, Catalyst 3550, Catalyst 2950, Catalyst 2950 LRE, Catalyst 3500 XL, Catalyst 2900 XL,
Catalyst 2900 LRE XL, and Catalyst 1900 series switches. Configuration cloning facilitates rapid
deployment of networks. The master switch automatically upgrades each stack.
• Cisco Network Assistant Software has been extended to include multilayer feature configurations such as
routing protocols, ACLs, and QoS parameters.
• Cisco clustering now supports member discovery and cluster creation across a single Cisco Catalyst 3750
Series switch routed hop, allowing the entire LAN to be managed through a single Web interface (and with
