Guidelines For
Interconnecting
Units
This section offers some guidelines for creating a Fabric. Using these
guidelines will help prevent problems arising when setting up your Fabric.
The maximum number of Switch units that can be interconnected is
■
eight.
It is not possible to create a fabric by interconnecting a 3Com Switch
■
5500 with any other 3Com device (such as 5500G Switch units) or mix
Enhanced Image (EI) Switch 5500 units with Standard Image (SI) units.
3Com strongly recommends that you upgrade all Switches to be
■
interconnected to the latest software agent.
3Com recommends that you remove the configuration file from a
■
Switch unit that has previously been used elsewhere in your network
before you interconnect to an existing unit. If you do not do this,
problems may be caused by conflicting Switch configurations. Use the
dir command from the User View to display the configuration files
stored on the Switch and locate the [filename].cfg file. Do NOT
under any circumstances remove the 3comoscfg.def file (this is the
default configuration file).
When a port is operating in XRN Fabric mode it will no longer be
■
configurable in the normal way, that is, you cannot control port
features such as auto-negotiation, VLANs, static addresses, STP,
Aggregated Links, Resilient Links, and so on. However, it is possible to
specify the Fabric VLAN.
For a detailed description of how XRN Technology operates and
implementation guidelines, please refer to the Configuration Guide on
the CD-ROM that accompanies your Switch.
