One Distributed Fabric.
Pay As You Grow
3Com XRN technology lets customers
cost-effectively upgrade their existing
core based on a single SuperStack 3
Switch 4900 or 3Com Switch 4050
and 4060, to a high-performance,
high-availability, 48-port multilayer
Gigabit switching core.
Network Level Availability
XRN technology lets customers design
and implement core Gigabit backbones
that feature no single point of failure—
a safeguard against hardware, cabling,
or software failure.
Performance and Scalability
The distributed nature of XRN
technology takes full advantage of the
high-performance, non-blocking
switching capacity of each switch in the
Distributed Fabric—yielding aggregate
forwarding capacity in excess of
70Mpps across the 48 switched Gigabit
ports.
Manageability
XRN Technology enables unprecedented
levels of manageability across the two
switches in the Distributed Fabric, by
offering "plug and play" setup of the
Fabric, single IP address management,
and fabric-wide configuration of all
management, system and port features.
Interconnect Kit
™
High Performance Layer 3 Switching
An XRN Distributed Fabric uses the
Layer 3 switching capabilitiies of both
switches for greater performance and
scalability but without the complexity
of managing two separate routers.
Distributed Link Aggregation
Configuring ports of an aggregated link
across both switches in a Distributed
Fabric enables wiring closets to be dual-
homed for greater availability and
performance across the network back-
bone.
Flexibility and Migration
An XRN Phase One Distributed Fabric is
built with any combination of SuperStack
3 Switch 4900 family or 3Com Switch
4050 and Switch 4060.
Advanced Security capabilities
Security features such as RADIUS Client
and Routed Access Control Lists ensure
authorized user access to network
resources. Also, Application Filtering
lets the XRN Distributed Fabric identify
and discard unauthorized applications.
Powerful Management
3Com Network Supervisor fully supports
XRN Phase One fabrics and provides
discovery, mapping, monitoring, and
alerting for easy network administration.
Network-wide switch traffic prioritiza-
tion can also be performed. The 3Com
Network Supervisor Advanced Package
increases the number of IP devices
supported and provides advanced con-
figuration capabilities such as bulk
software upgrades.
