Benefits of XRN

XRN Features

Distributed Device
Management (DDM)
Distributed Resilient
Routing (DRR)
The benefits of XRN include:
Increased environmental resilience provided by:
n
Hardware and Software redundancy per unit or across the Distributed
n
Fabric.
Distributed management across the Distributed Fabric.
n
Distributed Link Aggregation across the Distributed Fabric.
n
Distributed Resilient Routing across the Distributed Fabric.
n
Increased network performance provided by:
n
Switching capacity that increases as you add a Switch to the Fabric. So
n
network performance and resilience expand as the Fabric grows.
Link Aggregation supported across the Distributed Fabric.
n
Flexibility provided by:
n
Support across any of the Switches within an individual 3Com Switch 5500
n
family to create an XRN Distributed Fabric.
This section describes the key features of XRN.
DDM provides single IP address management across the interconnected Switches
that form the Distributed Fabric. This allows the entire Distributed Fabric to be
managed and configured as a single managed entity. In the event of failure in one
of the Switches in the Distributed Fabric, management access to the remaining
Switch is retained on the same IP address.
DDM allows you to manage the Distributed Fabric using the command line
interface (CLI), Web interface, or SNMP.
DDM provides you with the ability to carry out the following:
Single step Switch software upgrades across the Distributed Fabric (provided
n
the Switches are of the same family).
Distributed Fabric-wide configuration of all software features.
n
Configuration of port-specific software features across the Distributed Fabric
n
using a single management interface.
DRR allows the Switches in the Distributed Fabric to act as a single logical router
which provides router resiliency in the event of failure in one of the interconnected
Switches. With DRR, Switches in the Distributed Fabric are routing, which
significantly increases the overall Layer 3 capacity of the core of the network.
DRR can intelligently distribute the routing load across both Switches in the
Distributed Fabric, which maximizes routing performance and makes full use of
bandwidth capacity.
Switches in the Distributed Fabric provide Layer 3 local forwarding for directly
connected hosts and devices.
