Features and benefits
Quality of Service (QoS)
•
Broadcast control: allows limitation of broadcast
traffic rate to cut down on unwanted network
broadcast traffic
•
Advanced classifier-based QoS: classifies
traffic using multiple match criteria based on Layer
2, 3, and 4 information; applies QoS policies such
as setting priority level and rate limit to selected
traffic on a per-port or per-VLAN basis
•
Powerful QoS feature: supports the following
congestion actions: strict priority (SP) queuing,
weighted round robin (WRR), weighted fair queuing
(WFQ), and WRED
•
Traffic policing: supports Committed Access Rate
(CAR) and line rate
Management
•
Friendly port names: allow assignment of
descriptive names to ports
•
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
•
Command authorization: leverages
HWTACACS to link a custom list of CLI commands
to an individual network administrator's login; also
provides an audit trail
•
Secure Web GUI: provides a secure, easy-to-use
graphical interface for configuring the module via
HTTPS
•
Multiple configuration files: can be stored to
the flash image
•
Complete session logging: provides detailed
information for problem identification and resolution
•
SNMPv1, v2c, and v3: facilitate centralized
discovery, monitoring, and secure management of
networking devices
•
Remote monitoring (RMON): uses standard
SNMP to monitor essential network functions;
supports events, alarm, history, and statistics group
plus a private alarm extension group
•
IEEE 802.1AB Link Layer Discovery Protocol
(LLDP): automated device discovery protocol
provides easy mapping by network management
applications
•
Management VLAN: segments traffic to and
from management interfaces, including CLI/telnet, a
Web browser interface, and SNMP
•
Local and Remote Intelligent Mirroring:
mirrors traffic from a switch port to remote switch
port anywhere on the network, or mirrors
ACL-selected traffic to a local switch port
•
Device Link Detection Protocol (DLDP):
monitors a cable between two switches and shuts
down the ports on both ends if the cable is broken,
preventing network problems such as loops
•
Troubleshooting: ingress and egress port
monitoring enable network problem solving; virtual
cable tests provide visibility into cable problems
•
sFlow (RFC 3176): provides scalable ASIC-based
wire-speed network monitoring and accounting with
no impact on network performance; this allows
network operators to gather a variety of
sophisticated network statistics and information for
capacity planning and real-time network monitoring
purposes
•
Remote Intelligent Mirroring: mirrors
ingress/egress ACL-selected traffic from a switch
port or VLAN to a local or remote switch port
anywhere on the network
•
IPv6 management: future-proofs networking, as
the switch is capable of being managed whether the
attached network is running IPv4 or IPv6; supports
pingv6, tracertv6, Telnetv6, TFTPv6, DNSv6,
syslogv6, FTPv6, SNMPv6, DHCPv6, and RADIUS
for IPv6
Connectivity
•
Auto-MDIX: automatically adjusts for
straight-through or crossover cables on all 10/100
and 10/100/1000 ports
•
Jumbo packet support: supports up to
9216-byte frame size to improve the performance of
large data transfers
•
Gigabit Ethernet uplinks: dual-personality ports
for either 10/100/1000 or mini-GBIC SFP
connectivity for increased connectivity flexibility
•
High-density access: provides up to 48 fixed
10/100BASE-T PoE or non-PoE ports in a Layer
2/Layer 3 switch
