Features and benefits
Quality of Service (QoS)
•
Storm restraint: allows limitation of broadcast,
multicast, and unknown unicast traffic rate to cut
down on unwanted broadcast traffic on the network
•
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 bi-directional
selected traffic on a per-port, per-VLAN, or whole
switch basis
•
Powerful QoS feature: creates traffic classes
based on ACLs, IEEE 802.1p precedence, IP, DSCP
or ToS precedence; supports filter, redirect, mirror,
or remark; supports the following congestion
actions: strict priority queuing (SP), weighted round
robin (WRR), SP+WRR, weighted fair queuing
(WFQ), and weighted random early discard
(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
•
Dual flash images: provide independent primary
and secondary operating system files for backup
while upgrading
•
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 of network management
applications
•
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
•
Management VLAN: segments traffic to and
from management interfaces, including CLI/telnet, a
Web browser interface, and SNMP
•
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
•
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
•
IPv6 management: provides future-proof
networking because 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
•
Troubleshooting: ingress and egress port
monitoring enable network problem solving; virtual
cable tests provide visibility into cable problems
•
In-Service Software Upgrade (ISSU): enables
operators to perform upgrades in the shortest
possible amount of time with minimal risk to network
operations or traffic disruptions
Connectivity
•
Auto-MDIX: automatically adjusts for
straight-through or crossover cables on all
10/100/1000 ports
•
Flow control: using standard IEEE 802.3x, it
provides back pressure to reduce congestion in
heavy traffic situations
•
Jumbo packet support: supports up to
9216-byte frame size to improve the performance of
large data transfers
