Feature
Benefit
Tracking Users
•
DHCP Interface Tracker (Option 82) provides capabilities to locate a user on a network by providing switch and port
ID to a DHCP server. MAC Address Notification allows administrators to be notified of new users added or removed
from the network. Support for CiscoWorks User Registration Tool and the User Tracker in CiscoWorks Campus
Manager both provide the ability to track the location of users.
QUALITY OF SERVICE/CONTROL
Advanced Quality
of Service
•
802.1p CoS and Differentiated Services Code Point (DSCP) field classification via marking and reclassification on
a per packet basis using source/destination IP address, source/destination MAC address, or Layer 4 TCP/UDP port
number.
•
Automatic QoS (Auto-QoS) greatly simplifies the configuration of QoS in VoIP networks by issuing interface and
global switch commands that allow the detection of Cisco IP phones, the classification of traffic, and egress queue
configuration.
•
Cisco control plane and data plane quality of service ACLs on all ports to ensure proper marking on a per packet
basis.
•
Four egress queues per port supported in hardware to enable differentiated management of up to four types of traffic.
•
WRR scheduling to ensure differential prioritization of packet flows by intelligently servicing the egress queues.
•
WRED on all Gigabit Ethernet ports for avoidance of congestion at the egress queues before a disruption occurs.
•
Strict priority queuing to guarantee that the highest priority packets will always get serviced ahead of all other traffic.
•
No performance penalty for highly granular quality of service functionality.
Granular Rate-
Limiting
•
CIR functionality allows bandwidth to be guaranteed in increments as low as 8 Kbps.
•
Rate-limiting based on source/destination IP address, source/destination MAC address, or Layer 4 TCP/UDP
information or any combination of these fields using QoS ACLs (IP ACLs or MAC ACLs), class maps, and policy
maps.
•
Per port, per VLAN ingress policing enables the rate-limiting of individual VLANs on trunk ports.
•
Ability to easily manage data flows asynchronously upstream and downstream from the end station or on the uplink
via ingress and ingress policing.
•
8 aggregate or individual ingress policers and 8 aggregate egress policers on each 10/100 port.
•
128 aggregate or individual ingress policers and 8 aggregate egress policers on each Gigabit Ethernet port.
MANAGEABILITY
Cluster
Management Suite
•
Built-in Web-based Cisco CMS Software provides an easy- to-use Web-based management interface through a
standard Web browser.
•
Cisco AVVID Wizards use just a few user inputs to automatically configure the switch to optimally handle different
types of traffic: voice, video, multicast, and/or high-priority data.
•
A security wizard is provided to restrict unauthorized access to servers and networks, and restrict certain applications
on the network.
•
Cisco CMS Software allows the user to manage up to 16 inter-connected Cisco Catalyst 3550, 2950, 3500 XL, 2900
XL, 2900 LRE XL, and 1900 switches through a single IP address, without the limitation of being physically located
in the same wiring closet. Full backward compatibility ensures any combination of the above switches can be
managed with a Cisco Catalyst 3550 switch.
•
The cluster software upgrade feature allows the user to automatically upgrade the system software on a group of
Cisco Catalyst 3550, 2950, 3500 XL, 2900 XL, 2900 LRE XL, and 1900 switches.
•
Cisco Cluster Management Suite Software has been extended to include multilayer feature configurations such as
Routing Protocols, ACLs, and QoS parameters.
•
Clustering now supports member discovery and cluster creation across a single Catalyst 3550 routed hop, enabling
the entire LAN to be managed in a single web interface (and with a single IP address if desired).
