General InformationI

the creation of a single fabric. A segmented link transmits only Class F traffic; the link does not transmit Class 2 or Class 3 traffic. The following conditions cause ports to segment:

—Incompatible operating parameters - either the resource allocation time-out value (R_A_TOV) or error-detecttime-out value (E_D_TOV) is inconsistent between switches. To prevent port segmentation, the same E_D_TOV and R_A_TOV must be specified for each switch.

—Duplicate domain IDs - one or more domain ID conflicts are detected.

—Incompatible zoning configurations - zoning configurations for the switches are not compatible.

—Build fabric protocol error - a protocol error is detected during the process of forming the fabric.

—No principal switch - no switch in the fabric is capable of becoming the principal switch.

NOTE: At least one director or switch in a multi-switch fabric must be set to either principal or default, making it capable of becoming principal switch. If all directors and switches are set to never principal, all ISLs will segment (Reason code 05).

—Unresponsive switch - Each switch in a fabric periodically verifies operation of all attached switches. An ISL segments if the attached switch does not respond to a verification request.

—ELP retransmission failure timeout-a switch that exhibits a hardware failure or connectivity problem cannot transmit or receive Class F frames. The switch did not receive a response to multiple exchange link protocol (ELP) frames, did not receive a fabric login (FLOGI) frame, and cannot join an operational fabric.
