Features and benefits
Quality of Service (QoS)
•
Layer 4 prioritization: enables prioritization
based on TCP/UDP port numbers
•
Traffic prioritization (IEEE 802.1p): allows
real-time traffic classification into eight priority levels
mapped to eight queues
•
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 and per-port, per-queue guaranteed
minimums
•
Bandwidth shaping:
– Rate limiting: provides per-port, ingress-based
enforced bandwidth maximums
– Guaranteed minimums: provides per-port,
per-queue egress-based guaranteed bandwidth
minimums
•
Broadcast control: allows limitation of broadcast
traffic rate to cut down on unwanted broadcast
traffic on the network
Management
•
Remote configuration and management: is
available through a secure Web browser or a
command-line interface (CLI)
•
Manager and operator privilege levels:
enable read-only (operator) and read-write
(manager) access on CLI and Web browser
management interfaces
•
Management VLAN: segments traffic to and
from management interfaces, including CLI/telnet, a
Web browser interface, and SNMP
•
RADIUS accounting support: separates RADIUS
accounting server support per SSID; provides
detailed session, usage, and billing information for
each client activity
•
Multiple configuration files: can be stored to
the flash image
•
Dual flash images: provide independent primary
and secondary operating system files for backup
while upgrading
•
Secure Web GUI: provides a secure, easy-to-use
graphical interface for configuring the module via
HTTPS
•
Command-line interface (CLI): provides a
secure, easy-to-use command-line interface for
configuring the module via SSH or a switch console;
provides direct real-time session visibility
•
SNMPv1, v2c, and v3: facilitate centralized
discovery, monitoring, and secure management of
networking devices
•
Port mirroring: enables traffic on a port to be
simultaneously sent to a network analyzer for
monitoring
•
3Com-heritage Comware Operating
System: CLI and Web user interface in common
with HP E4xxx and E55xxx series switches
Connectivity
•
Auto-MDIX: automatically adjusts for
straight-through or crossover cables on all 10/100
and 10/100/1000 ports
•
Dual-personality functionality: includes four
10/100/1000 ports or SFP slots for optional fiber
connectivity such as Gigabit-SX, -LX, -LH, or 100-FX
•
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
•
Optional 10 Gigabit Ethernet ports: allow the
addition of 10 Gigabit Ethernet connections for
uplinks or high-bandwidth server connections;
flexibly supports XFP, SFP+, or CX4 local
connections
Manageability
•
RMON (remote monitoring): provides
advanced monitoring and reporting capabilities for
statistics, history, alarms, and events
•
Dual flash images: provides independent
primary and secondary operating system files for
backup while upgrading
•
Full-featured console: provides complete control
of the switch with a familiar command-line interface
(CLI)
•
Web interface: allows configuration of the switch
from any Web browser on the network
•
Multiple configuration files: allow multiple
configuration files to be stored to flash image
•
Software updates: free downloads from the
Web
•
sFlow (RFC 3176): wire-speed traffic accounting
and monitoring
