Техническая Спецификация для 3com 3CDSG8
The Switch family also supports a compact Command
Line Interface (CLI) that is accessed via the front panel
console port. Using the CLI, initial switch configuration
and setup can be done quickly.

DESCRIPTION
Performance
VLANs
Segment the network by grouping users based on their data or traffic exchange
requirements. This ensures optimal use of available bandwidth as traffic flow is directed
according to the needs of the business.
requirements. This ensures optimal use of available bandwidth as traffic flow is directed
according to the needs of the business.
Advanced QoS and traffic shaping
Traffic prioritization, using IEEE 802.1p Quality of Service (QoS) and Type of Service (TOS)
with Differentiated Services Code Point (DSCP), help ensure that critical time-sensitive
traffic like voice gets the priority needed for quality communications.

traffic like voice gets the priority needed for quality communications.
Link aggregation (trunking)
Group together any number of ports automatically using Link Aggregation Control
Protocol (LACP), or manually, to form an ultra-high-bandwidth connection to the
network backbone; help prevent traffic bottlenecks.

network backbone; help prevent traffic bottlenecks.
Rapid Spanning Tree Protocol support
Improves network compatibility, scalability and availability.
IGMP snooping
Multicast filtering optimizes network performance, instead of flooding traffic to all ports.
Flexible Gigabit uplink
Daisychain multiple units together via the built-in copper Gigabit uplink port or connect
to a network backbone via SFP-based fiber modules.
to a network backbone via SFP-based fiber modules.
Fanless design
Silent operation whether used in a rack or desktop situation.
Security
IEEE 802.1X network access control
Provides standards-based security combined with local authentication.
Advanced Access Control Lists (ACLs)
MAC- and IP-based ACLs enable network traffic filtering and enhance network control.
Traffic monitoring (port mirroring)
Administrators can examine suspect data streams received on any port by mirroring the
data stream to a
data stream to a
monitoring port.
Configuration and management
Enhanced browser-based interface
User interface allows even the most novice users to configure the switch during initial
setup and monitor it during normal operation.
setup and monitor it during normal operation.
SNMP support
Switch can be managed with SNMP-compatible tools.
Cable diagnostics
Remotely detect copper cable issues using a browser-based tool.
