XRN Fabric Configuration 245
Otherwise, you cannot enable the fabric port. For detailed restrictions, refer to
the error information output by devices.
■ When configuring XRN, do not configure other functions, and before
configuring other functions, make sure the fabric has been established and
works normally.
■ After a fabric is established, do not remove or plug in the cables used to form
the fabric or shut down/bring up a fabric port, do not modify the unit ID of the
device, and keep stability of the links between fabric ports to avoid fabric split.
■ In an XRN fabric, it is required to keep the global configurations on all the
fabric members consistent. If the global configurations on a switch are
different from those on other switches, XRN will restart the switch forcibly and
generate the same global configurations for the switch. Therefore, before
building an XRN fabric, make sure the global configurations on all the switches
are the same, and backup the existing configurations as needed to avoid
configuration loss in case of switch restart.
■ Do not modify the global configurations of any member switch when an XRN
fabric is being built or the topology is unstable, so as to avoid switch restart
due to global configuration inconsistency of member switches.
■ If a Switch 5500G with half-slot module exists in a fabric, control the number
of VLANs to raise the stability of the XRN fabric.
