An E_Port is fenced because of a protocol error. Depending on failure
cause, additional information and event codes are available at the
product or attached switch. Perform one of the following:
• The E_Port is segmented and accompanied by primary event
code 070. Go to step
• The fiber-optic cable is disconnected, the cable failed or is
degraded, or the port optical transceiver failed. The failure is
accompanied by a primary event code indicating the failure
type. Go to MAP 0000: Start MAP
the primary event code. Exit MAP.
• The E_Port is fenced because of persistent incomplete operations
(ISL bouncing). Go to
isolation at the attached switch. Exit MAP.
• The E_Port is fenced because of application-layer protocol
errors. Go to MAP 0000: Start MAP
the attached switch. Exit MAP.

An E_Port is fenced because devices connected to the attached fabric
element are flooding the ISL with frames (hot I/O). These link-level
problems are typically associated with legacy devices, arbitrated loop
devices, or magnetic tape drives. Perform one of the following:
• Disconnect the ISL. Exit MAP.
• Refer to the manufacturer's documentation and perform fault
isolation at the attached device or fabric element. Exit MAP.
• Change port fencing threshold settings to more lenient values.
Go to step 20.

An E_Port is fenced because of persistent firmware-related security
violations (SANtegrity binding or SANtegrity authentication
failures).
