Fabric segmentation occurs when two or more switches are joined together by ISLs and do not communicate to each other. Each switch appears as a separate fabric when you use the fabricShow command. Symptom Probable cause and recommended action Port gets segmented due to zone conflict Occurs even when one of the following is true. ∙ Zoning is enabled in both fabrics and the zone configurations are different in each fabric. ∙ The name of a zone object in one fabric is also used for a different type of zone object in the other fabric. A zone object is any device in a zone. ∙ The definition in one fabric is different from the definition of a zone object with the same name in the other fabric. To resolve the conflict, ensure that the following are true: ∙ The effective cfg (zone set) on each end of the segmented ISL is identical. ∙ Any zone object with the same name has the same entries in the same sequence. Symptom Probable cause and recommended action Fabric segmentation is caused by a "configuration mismatch". Occurs when zoning is enabled in both fabrics and the zone configurations are different in each fabric. Brocade Fabric OS Troubleshooting and Diagnostics Guide 76 53-1004126-01
