 XRN

In the event of a failure within your XRN network, 3Com recommends that you 
follow the recommendations below.

The steps below outline the procedure to recover your XRN network in the event 
of a unit failure within your Distributed Fabric. 

1 Obtain a Switch and ensure it is installed with the same software version as the 

failed Switch.

2 Initialize the new Switch so it is operating with its factory default settings.

3 Connect the new Switch to the operational Switch to form the Distributed Fabric.

4 IP interfaces and VLANs will be converged between the Switches, that is, IP 

interfaces and the creation of the VLANs is done automatically on the new Switch. 
However, any port-based configuration must be done manually.

5 If any Switch features, for example, IGMP snooping or passwords are not set to 

default state then these should be reset after the new Distributed Fabric has been 
formed.

The steps below outline the procedure to recover your XRN network in the event 
of an interconnect failure within your Distributed Fabric. 

1 Obtain a new cable.

2 Install the new cable.

This section provides guidelines on connecting legacy and new 3Com Switches 
(including non-XRN enabled Switches) to an XRN Distributed Fabric. Table 694 lists 
the features supported by the Switches that can be used when connecting to a 
Distributed Fabric.

For detailed information on how the Switch features interact with XRN , refer to 
the “How XRN Interacts with other Features” on page 681.
