• Autosensing on all 10/100 ports automatically
selects half- or full-duplex transmission mode to
optimize bandwidth.
• Autoconfiguration eases switch deployment in the
network by automatically configuring multiple
switches across a network via a boot server.
• Default configuration stored in Flash memory
ensures that a switch can be quickly connected to
the network, pass traffic with minimal user
intervention, and preserve configuration in case of a
power outage.
Integrated Cisco IOS Software
Switching Solution
• Cisco GroupManagement Protocol (CGMP)enables
a switch to selectively and dynamically forward
routed IP multicasttraffic totargeted multimediaend
stations, reducing overall network traffic.
• CGMP Fast Leave allows end stations to quickly
exit from a multicast session, reducing superfluous
network traffic.
• Virtual LAN trunks can be created from any port
using standards-based 802.1Q tagging.
• Private VLAN Access enables per port security,
requiring only a VLAN on every switch, not every
port. This feature greatly minimizes the number of
VLANs required.
• IEEE 802.1p Layer 2 protocol for prioritization of
mission-critical and time-sensitive traffic from data,
video, voice, and IP telephony applications.
• Cisco Virtual Trunking Protocol (VTP) supports
dynamic VLANs and trunk configuration across all
switches.
• Cisco IOS command-line interface (CLI) support
provides common user interface and command set
across all Catalyst switches and Cisco routers.
• Cisco Discovery Protocol (CDP) enables a
CiscoWorks network management station to
automatically discover a switchin a networktopology.
Superior Manageability
• Built-in, Web-based management interface provides
easy-to-usemanagement through astandardbrowser
such as Netscape Navigator or Microsoft Explorer.
• Web-based, remote monitoring of the Cisco 575
LRE and 585 LRE CPE devices from a Catalyst
2900 LRE XL switch.
• Simple Network Management Protocol (SNMP)
and Telnet interface support deliver comprehensive
in-bandmanagement,and a CLI-basedmanagement
console provides detailed out-of-band management.
• Manageable through CiscoWorks2000 network
management software on a per-port and per-switch
basis, providing a common management interface
for Cisco routers, switches, and hubs.
• 8-MB DRAM and 4-MB Flash memory onboard,
enabling the addition of a continuous stream of
feature upgrades and maximizing customer
investments.
• Configurable network port, supporting unlimited
Media Access Control (MAC) addresses for
backbone connectivity.
• Embedded Remote Monitoring (RMON) software
agent supports four RMON groups (history,
statistics, alarms, and events) for enhanced traffic
management, monitoring, and analysis.
• Support for allnine RMONgroupsthrough useof a
switchportanalyzer(SPAN)portthatpermits traffic
monitoring of a single port, a group of ports, or the
entire switch from a single network analyzer or
RMON probe.
• Domain Name System (DNS) client support
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 TimeProtocol (NTP)provides an accurate
and consistent timestamp to all switches within the
intranet.
