Features & Benefits

LAN SWITCHES

CORE CHASSIS

These chassis-based switches offer end-to-end connectivity and granular application

control for enterprise campus and metropolitan area networks (MAN). They are

ideal for deployment in environments where uninterrupted running of network

applications and a high level of performance, security and control are required.

Featuring a flexible modular architecture and industry standard compliance, these

switches provide scalable expansion and a high level of investment protection for

businesses and telecom carriers to deploy Gigabit and 10-Gigabit packet switching

and routing for office networking and Ethernet-based Internet services to the

homes.

These switches feature minimum or zero network downtime, robust security and

real-time running of bandwidth-intensive applications. Equipped with high-speed

switch fabrics, redundant backup/load sharing capability and advanced software

functions including complete IPv6 support, these switches provide the performance,

high availability and future-proof architecture suitable for applications of not just

today but well into the future.

These switches provide not only network access security but also protection against

virus and worm attacks. Access security is provided through comprehensive policy-

based ACL, port security, IP-MAC-Port binding features and Defeat IP Scan, while

attacks hidden behind control protocols are thwarted to prevent the switch’s CPU

from being overwhelmed with unnecessary tasks which can cause degradation to

a network’s performance. These switches extend security to network management

via such functions as SSH v2 and SNMP v3 with authentication and encryption of

management traffic.

» Core switch provides numerous high-speed

fiber backbones for a campus and central

office network.

» Aggregation switch can provide high port

density connections to workstations in an

office environment, or to subscribers’ CPE

in a densely populated Ethernet metro area

network.

» Each line card can perform L2/3/4 on-board

packet switching without relying on the control

card.

» The switch synchronizes the switching and

routing information between the control card

and the line cards to map out the fastest data

transfer path
