• CPU OIR
• Device reload
• IOS-XR reload
• System admin reload
• mxp_driver process restart
Hitless restart or the headless functionality is enabled only if the slice is successfully provisioned. This mode is disabled
if any one of the following configurations are in progress or have failed on the slice:
•
shutdown
or
no shutdown
of optics, Ethernet, or coherent DSP controllers.
• Transmit power configurations
• DWDM carrier frequency configuration
• Client and trunk loopback configurations
• FEC mode configuration
• Transmit TTI configuration
• Expected TTI configuration
During CPU OIR, or a reload operation, if a slice is initialized in the stateful mode and any datapath hardware component
is not accessible, the headless feature aborts the reprovisioning of the slice to prevent any traffic impact.
