System Actions

When the Ethernet ports work in active/standby mode, a switchover is performed between the active port and the standby port.

Possible Causes

• The physical connection of the Ethernet port is faulty.
• The Ethernet port is deactivated.
• The peer equipment is faulty.
• Negotiation fails between the local and peer ports because of inconsistency in the work mode or rate configured for both ports.
• The sub-board of the board to which the Ethernet port belongs is faulty.
• The optical module is not inserted or is abnormal.
