This object governs which interface types are visible to SNMP management clients that use the standard ifTable, ifXTable and ifStackTable. The object is a variable length octet string that is interpreted as a bit mask. Each bit respresents a specific Juniper interface type that can be included or excluded in the standard interface tables. For each bit position in each octet of the string, a '1' or '0' indicates the corresponding interface type is either removed (compressed) from the standard interface MIB tables, or included respectively. Individual bit definitions follow the JuniIfType convention defined in the Juniper-UNI-IF-MIB. For example, ip(0) and ppp(1) correspond to bit definitions 0 and 1 respectively. In each octet, bit 0 is least significant, bit 7 most significant. This configuration is applicable to all interface related tables until interface compression based on interface table-types is applied. If interface table-type based compression is applied, get operation on this object will correspond only to ifTable/ifXTable/juniIfTable and set operation on this object will fail.
