The 3Com

Switch 7700 modular LAN switch

family delivers high-performance, multilayer,

10 Gigabit, Gigabit, and Fast Ethernet switching

and routing in a scalable, flexible, modular

chassis. Three chassis configurations are

offered:

• High-availability 8-slot redundant chassis,

with six payload slots, primary switch

fabric, and optional backup switch fabric.

• 7-slot, with six payload slots plus switch

fabric.

• 4-slot, with three payload slots, switch

fabric, and optional plug-in submodule

supporting four additional Gigabit ports.

The resilient systems architecture helps

provide business network continuity for

data and voice convergence applications—

required in demanding core and campus

environments.

The 3Com Switch 7700 is ideal for campus and

building-level switching in the core, with

support for up to six 10 Gigabit or 120 Gigabit

ports. The availability of high-density 10/100

ports for a Switch 7700 configuration makes it

appropriate for wiring closet distribution or

edge installations.

The Switch 7700R 8-Slot chassis is designed

for networking environments demanding the

highest level of resiliency. When configured

with an optional spare switch fabric, the

Switch 7700R boasts sub-one-second switch

fabric failover should there be a primary

fabric failure, helping ensure continuous

network operation.

Fault-tolerant aggregation features in the

Switch 7700 family include Virtual Router

Redundancy Protocol (VRRP), Rapid Spanning

Tree Protocol (RSTP), Spanning Tree Protocol

(STP), Multiple Spanning Tree Protocol

(MSTP), and link aggregation for virtually

non-stop network availability. The architecture

of the Switch 7700 supports a passive

backplane and N+1 redundant power

supplies for seamless network operation.

The Switch 7700 family supports IP

(RIP, OSPF), IPX, and IGMP PIM (DM

and SM) multicast routing for logical

network segmentation and traffic

control. Advanced QoS features provide

differentiated network services for traffic

classification and prioritization based on

Diffserv Code point, Type of Service (ToS),

and IEEE 802.1p Class of Service (CoS).

Advanced Bandwidth management allows

different traffic flows to be shaped using

packet priority, minimum and maximum

bandwidth thresholds, and individual flow

weightings.

These features enable optimal priority

queuing of network data, helping to ensure

minimal congestion for important traffic.

Routing in hardware of multicast traffic for

voice and video streaming enables minimal

latencies through the switch.

The network can be secured from unautho-

rized access through IEEE 802.1X RADIUS

Network Login, Access Control Lists and

management authentication. The chassis

supports most cabling requirements and

offers comprehensive management for simple

configuration and advanced network

monitoring and troubleshooting.

The switch fabric of the 7700 4-Slot chassis

supports sub-modules for additional gigabit

(1000BASE-T or 1000BASE-X GBIC ports)

connections. This is particularly helpful

when Gigabit ports are required for an

uplink, and the payload slots contain Fast

Ethernet modules.
