Mixed stacking devices
A mixed stack contains ICX 6610 devices and ICX 6450 devices. ICX 6610 devices form the backbone of the mixed stack. ICX 6450 devices are peripheral units that connect to the backbone and to other peripheral units.
A mixed stack can contain one or two ICX 6610 devices and one to six ICX 6450 devices. ICX 6610 devices have full Layer 2 and Layer 3 unicast and multicast capabilities. ICX 6450 devices support full Layer 2 switching and basic Layer 3 routing capabilities.
In a mixed stack, all Layer 3 functions are performed by the ICX 6610 devices. Layer 3 traffic received on ICX 6450 devices is redirected to the ICX 6610 devices.
