This document describes how to read and understand alert messages from failover of nic pairing.
Background Information
Cisco Email Security Appliances (ESA) can be configured to send out alert notifications. When NIC pairing is
used, it is common to receive an alert when the interfaces fail−over. Two alerts are generated:
used, it is common to receive an alert when the interfaces fail−over. Two alerts are generated:
Port Data 1 failure, switching to Data 2
Recovered network using port Data 2
When the ESA validates network connectivity, it checks for a carrier signal on the line and attempts to ping
the configured gateway. If either of these fail, the ESA switches to the backup interface. Some switches
occasionally cause ESA's to fail−over. If this happens frequently, and there is no issue with the physical
connection or with the switch, it may make sense to verify the speed and duplex settings on both the ESA and
the switch.
