Features and benefits
Quality of Service (QoS)
•
Traffic prioritization (IEEE 802.1p)
allows real-time traffic classification with support for eight priority
levels mapped to either two or four queues; uses weighted deficit
round robin (WDRR) or strict priority (SP)
•
Simplified QoS configuration
– Port-based
prioritize traffic by specifying a port and priority level
– VLAN-based
prioritize traffic by specifying a VLAN and priority level
•
Class of Service (CoS)
sets the IEEE 802.1p priority tag based on IP address, IP Type of
Service (ToS), Layer 3 protocol, TCP/UDP port number, source port,
and DiffServ
•
Rate limiting
sets per-port ingress enforced maximums for all ingressed traffic,
or for broadcast, multicast, or unknown destination traffic
•
Layer 4 prioritization
enables prioritization based on TCP/UDP port numbers
•
Flow control
helps deliver reliable communication during full-duplex operation
Management
•
Choice of management interfaces
– Web graphical user interface (GUI)
HTML-based easy-to-use graphical interface allows configuration
of the switch from any Web browser
– Command-line (CLI)
robust command-line interface provides advanced configuration
and diagnostics
– Simple Network Management Protocol (SNMPv1/v2c/v3)
allows a switch to be managed with a variety of third-party
network management applications
•
Virtual stacking
single IP address management of up to 16 switches
•
sFlow (RFC 3176)
wire-speed traffic accounting and monitoring configured by SNMP
and CLI with three terminal encrypted receivers
•
IEEE 802.1AB Link Layer Discovery Protocol (LLDP)
automates device discovery protocol for easy mapping by network
management applications
•
Logging
provides local and remote logging of events via SNMP (v2c and v3)
and syslog; provides log throttling and log filtering to reduce the
number of log events generated
•
Port mirroring
allows traffic to be mirrored on any port or a network analyzer to
assist with diagnostics or detecting network attacks
•
RMON (remote monitoring)
provides advanced monitoring and reporting capabilities for
statistics, history, alarms, and events
•
Find-Fix-and-Inform
finds and fixes common network problems automatically, then
informs the administrator
•
Friendly port names
allow assignment of descriptive names to ports
•
Dual flash images
provide independent primary and secondary operating system files
for backup while upgrading
•
Multiple configuration files
allow multiple configuration files to be stored to a flash image
•
Front-panel LEDs
– Locator LED
allows users to set the locator LED on a specific switch to either
turn on, blink, or turn off; simplifies troubleshooting by making it
easy to locate a particular switch within a rack of similar switches
– Per-port LEDs
provides an at-a-glance view of status, activity, speed, and
full-duplex operation
– Power and fault LEDs
display any issues
Connectivity
•
IPv6
– IPv6 host
allows the switch to be deployed and managed at the edge of an
IPv6 network
– Dual stack (IPv4/IPv6)
supports connectivity for both protocols; provides a transition
mechanism from IPv4 to IPv6
– MLD snooping
forwards IPv6 multicast traffic to the appropriate interface;
prevents IPv6 multicast traffic from flooding the network
•
IEEE 802.3af Power over Ethernet (PoE)
provides up to 15.4 W per port to IEEE 802.3af-compliant
PoE-powered devices such as IP phones, wireless access points, and
security cameras
•
IEEE 802.3at Power over Ethernet Plus
provides up to 30 W per port to IEEE 802.3 for PoE/PoE+ powered
devices such as video IP phones, IEEE 802.11n wireless access
points, and advanced pan/tilt/zoom security cameras (see product
specifications for total PoE power available)
•
Auto-MDIX
adjusts automatically for straight-through or crossover cables on
all ports
