This appendix illustrates the clocking strategy for various modes of MRMAC operation.
Emphasis is placed on showing how one mode can dynamically evolve into another. For example, the MRMAC might start off configured as 4 × 10G clients but then dynamically re-configure into a 1 × 50G + 10G + 25G configuration.
Important: GTM will be available in a
future release.
