ENTERPRISE-WIDE SECURITY
Security is paramount in today's enterprise and as dependency on
information technology continues to rise, so does the need for highly
secure IT systems and infrastructures. The 3Com Switch 7750 features
advanced security capabilities, including user and device authentication,
policy-based access controls, encrypted system management access and
quarantine enforcement for containment of vulnerabilities and deliberate
attacks.
The Switch 7750 ensures secure network access using standard IEEE
802.1X network login with RADIUS Authenticated Device Access (RADA).
RADIUS support enables user authentication, while the switch is also able
to authenticate attached devices (printers, for example) via their MAC
address for an additional level of endpoint security. Port- and VLAN-based
Access Control Lists (ACLs) and dynamic traffic filtering capabilities can be
deployed to further control access to network resources.
Additional security measures—Secure Shell version 2 (SSH v2) and
SNMP v3 with authentication and encryption of network management
traffic—are enforced when accessing switch management utilities.
The Switch 7750 Family functions as an integral part of the 3Com
Quarantine Protection solution to automate containment of security
threats on the enterprise network. Quarantine Protection integrates the
industry-leading TippingPoint
™
switch-based endpoint enforcement at the network edge.
SCALABLE PERFORMANCE
With up to 240 Gbps of system bandwidth and wirespeed switching
capacity, the Switch 7750 provides exceptional scalability for Enterprise
distribution and edge environments and for core networks of mid-market
businesses. Connectivity and media options can be tailored to each
environment with a wide selection of switching modules, scaling up
to 292 Gigabit ports or 288 Fast Ethernet ports in a single chassis.
10-Gigabit Ethernet uplink modules allow ultra-high-bandwidth links
for inter-switch backbone connections The flexible design of the Switch
7750 allows for any combination of switching modules to be used in a
single system, allowing easy expansion of network capacity with a
wide selection of standard interface types for twisted pair (copper)
and fiber media.
A 96 Gbps switching fabric provides high-performance switching,
routing and centralized management in the Switch 7750. In addition,
individual switching I/O modules provide on-board local switching,
maximizing system performance and application response times, for
an aggregate Layer 2/3 switching capacity of up to 179 Mpps.
Hardware-based routing of multicast traffic enhances performance and
reduces latency (delay) for multicast applications, enhancing performance
for real-time applications like streaming audio and video.
Standards-based link aggregation (via IEEE 802.3ad) allows scalable,
high-bandwidth interconnectivity between network devices, with the
ability to aggregate multiple Gigabit links together as a single trunk.
Link aggregation of Gigabit ports is supported across fabric modules
within the Switch 7758 chassis (when configured with redundant fabrics)
for enhanced network availability.
