Layer 3 Chassis Switch
Chassis Switch
Layer 3 Chassis Switch
For Departmental/Enterprise Network Connections
The DES-6500 is a core Layer 3 chassis-based Gigabit switch that provides everything a business needs for a switched network.
This 9-slot chassis offers a high port density, comprehensive network media support with multiple link aggregation, a high
switch fabric capacity of 160Gbps supporting wire-speed L2/L3 packet switching, fault tolerance with line card hot-swap and
redundant power backup capabilities, Quality of Service (QoS)/Class of Service (Cos), complete user access security, traffic
monitoring and comprehensive network management. Designed for performance and flexibility, this chassis offers you the edge
device router simplicity and the price/performance ratio necessary to deploy a cost-effective enterprise, backbone and campus
Wire-speed IP Packet Routing
Using standards-based routing, the DES-6500 provides
instant support for Windows, Unix and Internet
environments. Built-in wire-speed non-blocking switch
fabric provides hardware-based packet filtering/forwarding.
Packet routing is performed by on-board ASICs, which is
many times faster than traditional CPU-based routers.
Up to 96 Gigabit Ports, 192 Ethernet Ports
You can configure the switch with up to 96 Gigabit ports,
192 twisted-pair Ethernet ports, or 96 fiber Ethernet ports, or
a combination of these. Copper Gigabit and fiber Gigabit
(SX, LX and SFP included) are supported. This
comprehensive network media support allows you to
flexibly configure the chassis for workstations, departmental
server and backbone/campus connections.
Scalable Expansion
With 8 line card slots and a wide range of user-selectable
port types, the DES-6500 allows you to easily add modules
to increase port density as your need grows, without
changing your chassis.
High Availability
The hardware and software features of the DES-6500 work
together to allow customers to build affordable, high
performance, high availability networks. Line card hot-swap
capability makes it easy to add or remove line cards to
simplify troubleshooting and replace sparing. The DES6500 also supports redundant power option to maximize
Network uptime. Other features include support for RIP v.1,
V.2, OSPF, DVMRP, 802.3ad Link Aggregation, 802.1d
Spanning Tree, and 802.1w Rapid Spanning Tree for
increased network reliability and availability.
Network Management
The DES-6500 supports a variety of network management
options including: console CLI, Telnet configuration, webbased and SNMP v.1, v.2c, v.3 management, RMON
monitoring, TFTP firmware upgrade, Port Mirroring for
troubleshooting, BootP and DHCP IP assignment. The DES6500 also supports a variety of advanced traffic management
options including: 802.1x, Bandwidth Control, Broadcast
Rate Limiting, and support for IGMP v.1, v.2 snooping.
Advanced Enterprise Features
The DES-6500 implements a robust and consistent set of
QoS/CoS, VLAN, and Security features. It provides a
complete set of network access management, plus multilayer (L2, L3, L4) Quality of Service support, advanced
Access Control Lists (ACL) support, and enhanced
TACACS+ and RADIUS authentication.
The DES-6500 supports 8 priority queues for
802.1p/TOS/DiffServ, with classification and marking based
on MAC SA/DA, IP SA/DA, and/or TCP/UDP port numbers.
Security features include: 802.1x (port based authentication)
802.1x (MAC based authentication), Access Control Lists
based on MAC address, IP address, and/or TCP/UDP port
numbers. The DES-6500 also has extensive support for
GARP/GVRP, 802.1q, and 802.1Q VLANs for up to 4K
static groups per device.
