Console Commands

VCCMask

Use VCCMask (virtual channel connection mask) to manage the combination of VPI (virtual path identifier) bit and VCI (virtual channel identifier) bit settings. There are only four different VCC mask entries allowed by the switch and the VPI and VCI shift must total 12.

Administrator

Modifies the proportion of bits assigned to the VPI and VCI for a given VCC or VPI/VCI set. The combined total of VPI and VCI bits must equal 12. The four most common VCC masks are predefined in the system (see modify portconfig ). When modifying a VPI/VCI set, you must specify the VCC mask by using the mask index identifier. If you modify a specific mask index, for example a VPI/VCI set is modified from 6/6 to 7/5, you will modify occurrences of the 6/6 configuration on all ports, as only four different VCC masks configurations can exist at any one time.
