Features and benefits
Connectivity
•
Auto-MDI/MDIX
automatically adjusts for straight-through or crossover cables on
all 10/100/1000 ports
•
Packet storm protection
protects against broadcast, multicast, or unicast storms with
user-defined thresholds
•
IEEE 802.3af PoE-powered device option (8-port Gigabit models)
can obtain power from a standard PoE device on Port 1, making the
switch ideal for deployments where a power outlet is not available;
such flexibility helps you extend the network to wherever an
Ethernet cable can reach
•
SFP ports for fiber connectivity
– Three models with true non-combo SFP ports; two models with
combo dual personality SFP ports
use fiber connections for uplinks and other connections across
longer distances than copper cabling. True SFP ports operate in
addition to available copper Ethernet ports. Combo ports are
shared connections, either operating as a copper connection or as
a fiber connection.
Performance
•
Half-/Full-duplex auto-negotiating capability on every port
doubles the throughput of every port
•
Link aggregation (trunking)
brings together groups of ports automatically using Link
Aggregation Control Protocol (LACP) or, manually, to form an
ultra-high-bandwidth connection to the network backbone; helps
prevent traffic bottlenecks; the 8-port Gigabit models have four
trunks of four links each, the 24-port Gigabit models have eight
trunks of four links each, and the 1810-48G switch has 16 trunks of
eight links each
Quality of Service (QoS)
•
Traffic prioritization (IEEE 802.1p)
allows real-time traffic classification with eight priority levels
mapped to four queues
•
NEW IEEE 802.1p prioritization with DSCP (v2 models)
switch delivers data to devices based on the priority and type of
traffic using Differentiated Services Code Point (DSCP)
•
Broadcast control
allows limitation of broadcast traffic rate to cut down on unwanted
network broadcast traffic
Layer 2 switching
•
VLAN support and tagging
support up to 64 port-based VLANs and dynamic configuration of
IEEE 802.1Q VLAN tagging, providing security between workgroups
•
Jumbo packet support
supports up to 9220-byte frame size to improve the performance of
large data transfers
Resiliency and high availability
•
NEW IEEE 802.1D Spanning Tree Protocol (STP) and 802.1W Rapid
Spanning Tree Protocol (RSTP) (v2 models)
provides redundant links while preventing network loops
Security
•
Secure Sockets Layer (SSL)
encrypts all HTTP traffic, allowing secure access to the
browser-based management GUI in the switch
•
Automatic denial-of-service protection
monitors six types of malicious attacks and protects the network by
blocking the attacks
•
Management password
provides security so that only authorized access to the Web browser
interface is allowed
Ease of use
•
Locator LED (switch)
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
•
Comprehensive LED display with per-port indicators
provides an at-a-glance view of status, activity, speed, and
full-duplex operation
Flexibility
•
Flexible mounting options
mounting options include wall, desktop, or under table
configuration for flexible installation
•
Rack mountable (24- and 48-port models)
offers a rack-mounting option with included hardware
•
Kensington lock slot
allows switches to be physically secured in open-space
deployments
Management
•
Simple Web management
intuitive Web GUI allows for easy management of device by even
nontechnical users
•
Secure Web GUI
provides a secure, easy-to-use graphical interface for configuring
the module via HTTPS
•
SNMPv1, v2c
devices can be discovered and monitored from an SNMP
management station
•
Dual flash images
provide independent primary and secondary operating system files
for backup while upgrading
