EFM-OAM syslog messages
When EFM-OAM is enabled on an interface, the syslog messages in the following table are generated
when the link goes up or down, or when loopback mode is entered or cleared on an interface.

Hitless management on the FSX 800 and FSX 1600

Hitless management is supported on the FSX 800 and FSX 1600 chassis with dual management
modules. It is a high-availability feature set that ensures no loss of data traffic during the following
events:
• Management module failure or role change
• Software failure
• Addition or removal of modules
• Operating system upgrade
During such events, the standby management module takes over the active role and the system
continues to forward traffic seamlessly, as if no failure or topology change has occurred. In software
releases that do not support hitless management, events such as these could cause a system reboot,
resulting in an impact to data traffic.
The following Hitless management features are supported:
Hitless Switchover - A manually controlled (CLI-driven) switchover of the active and standby
management modules without any packet loss to the services and protocols that are supported by
Hitless management. A switchover is activated by the CLI command switch-over-active-role .
Hitless Failover - An automatic, forced switchover of the active and standby management modules
because of a failure or abnormal termination of the active management module. In the event of a
failover, the active management module abruptly leaves and the standby management module
immediately assumes the active role. Like a switchover, a failover occurs without any packet loss to
