NOTE
Layer 2 services and protocols that are not listed (not supported by the hitless feature) may
encounter disruptions during reset of the management and interface modules, but will resume
normal operation once the modules are back up and running.
Some advantages of a hitless switchover over a hitless software reload are:
•
A manual switchover is quicker, since the standby module does not have to reboot.
•
Switched traffic through the Ethernet interfaces on the standby management module is not
interrupted.
NOTE
If the current active management module is physically removed from the chassis without first
issuing the switch-over-active-role command, the standby module will still take over the active role,
but the chassis will reset and re-initialize all components. Thus, traffic going through the system will
be interrupted.
For a description of the events that occur during a hitless switchover, refer to
during a Hitless OS upgrade and Hitless switchover”
For a description this feature’s impact to major system functions, refer to

Executing a Layer 2 Hitless switchover
The CLI command for executing a hitless switchover is the same as for a switchover (non-hitless).
