Features and benefits
Quality of Service (QoS)
•
IEEE 802.1p prioritization: delivers data to
devices based on the priority and type of traffic
•
Traffic prioritization (IEEE 802.1p): allows
real-time traffic classification mapped to four
hardware queues per port
•
Layer 4 prioritization: enables prioritization
based on TCP/UDP port numbers
•
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
•
Broadcast control: allows limitation of broadcast
traffic rate to cut down on unwanted broadcast
traffic on the network
Management
•
Simple Web management: intuitive Web GUI
allows for easy management of device by even
nontechnical users
•
Single IP management: enables management
of up to 32 V1910 devices using a single Web
interface; simplifies management of multiple devices
•
Secure Web GUI: provides a secure, easy-to-use
graphical interface for configuring the module via
HTTPS
•
SNMPv1, v2c, and v3: facilitate centralized
discovery, monitoring, and secure management of
networking devices
•
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
•
Complete session logging: provides detailed
information for problem identification and resolution
•
Uni-Directional Link Detection (UDLD):
monitors cable between two switches and shuts
down the ports on both ends if the cable is broken,
turning the bi-directional link into uni-directional; this
prevents network problems such as loops
•
Dual flash images: provide independent primary
and secondary operating system files for backup
while upgrading
•
Port mirroring: enables traffic on a port to be
simultaneously sent to a network analyzer for
monitoring
•
Management security: multiple privilege levels,
with password protection, restrict access to critical
configuration commands; ACLs provide telnet and
SNMP access; local and remote syslog capability
allow logging of all access
•
Network Time Protocol (NTP): synchronizes
timekeeping among distributed time servers and
clients; keeps consistent timekeeping among all
clock-dependent devices within the network so that
the devices can provide diverse applications based
on the consistent time
•
IEEE 802.1AB Link Layer Discovery Protocol
(LLDP): automated device discovery protocol
provides easy mapping by network management
applications
•
DHCP options: client allows automatic setting of
IP address
•
Limited CLI: enables users to quickly deploy and
trouble shoot devices in the network
•
RMON: provides advanced monitoring and
reporting capabilities for statistics, history, alarms,
and events
Connectivity
•
Auto-MDI/MDIX: automatically adjusts for
straight-through or crossover cables on all
10/100/1000 ports
•
IEEE 802.3X flow control: provides a flow
throttling mechanism propagated through the
network to prevent packet loss at a congested node
•
* IEEE 802.3af Power over Ethernet (PoE)
ready: PWR models able to provide up to 15.4 W
per port to power standards-compliant IP phones,
wireless LAN access points, Web cameras, and
more
•
Packet storm protection: protects against
broadcast, multicast, or unicast storms with
user-defined thresholds
•
Jumbo Frames: allow high-performance remote
backup, server links, and disaster-recovery services
Performance
•
Half-/Full-duplex autonegotiating
capability on every port: doubles the
throughput of every port
