I am currently using myself as switch for the private network to allows data exchanges between nodes with 25G cards . Internet access to these nodes is still handledby 10G NICS connected to a CRS317-1G-166+RM which is connected to the CCR2004-1G-12S+2XS using a 10G LINK. Maybe this can be improved. ANyway I a mooling of some usage example of this switch outside of the ring described in another thread. Please share !
