McDATA Sphereon 4300 Fabric Switch Installation and Service Manual
Event Code Tables
Event Code: 081
Message: Invalid attachment.
Severity: Informational.
Explanation: A switch port recognized an incompatibility with the attached fabric element or device and isolated the port. An
isolated port does not transmit Class 2, Class 3, or Class F traffic. Refer to event data for the reason.
Action: Action depends on reason specified.
Event Data: The first byte of event data (byte 0) specifies the port number. The fifth byte (byte 4) specifies the isolation reason
as follows:
1 = Unknown - Reason is unknown, but probably caused by failure of an E_Port connected device. Fault isolate
the failed device or contact support personnel to report the problem.
2 = ISL connection not allowed - The port connection conflicts with the configured port type. Change the port
type to F_Port if the port is cabled to a device, or E_Port if the port is cabled to a fabric element to form an ISL.
3 = Incompatible switch - The switch returned a Process ELP Reject - Unable to Process reason code because
the attached fabric element is not compatible. Set the switch operating mode to McDATA Fabric 1.0 if connected
to a McDATA product. Set the switch operating mode to Open Fabric 1.0 if connected to an open-fabric compliant
product manufactured by a different vendor.
4 = Incompatible switch - The switch returned a Process ELP Reject - Invalid Revision Level reason code
because the attached fabric element is not compatible. Set the switch operating mode to McDATA Fabric 1.0 if
connected to a McDATA product. Set the switch operating mode to Open Fabric 1.0 if connected to an
open-fabric compliant product manufactured by a different vendor.
5 = Loopback plug connected - A loopback plug is connected to the port with no diagnostic test running.
Remove the loopback plug.
6 = N_Port connection not allowed - The switch is connected to a fabric element through a misconfigured port.
Change the port type to E_Port.
7 = Non-McDATA switch at other end - The attached fabric element is not a McDATA product. Set the switch
operating mode to Open Fabric 1.0 if connected to an open-fabric compliant product manufactured by a different
vendor.
8 = E_Port capability disabled - The product does not have E_Port capability. Enable this functionality through
the appropriate product feature enablement (PFE) key.
