DLCI Mapping/Filters

The Express L128/L128T can block packets in and out of a PVC port by use of

the filters. They are set up in two steps: 1) define the types of packets that

would be of interest in the Configuration/Security/Filter Defines menu, and

2) set up the filter type and combination of defines that will cause a packet

block.
