List of ports which are configured statically as blocked router ports. Each bit in this object represent interfaces denoted by the object fsVcHlPortId associated to the instance identifier denoted by fsSnoopVlanFilterInstId. This object alone should be referred in environments where the number of interfaces in the system is scaled to a large value, as the object fsSnoopVlanBlkRtrPortList may not be sufficient to represent the full set of interfaces in each switch instance.
