This type is not a standard SMI/SNMP base type and is not defined as a documented TEXTUAL-CONVENTION in this MIB.
It was extracted as raw syntax from the source MIB file and could not be resolved to a known type definition.
This object is used to set the trust state of an interface.
(whether the packets arriving at an interface are trusted to
carry the correct data for classification.)
If the object is untrusted(1), then the DSCP assigned to the
packet is the layer2 CoS value denoted by csqIfDefaultCos
object mapped to a DSCP by the CoS-to-DSCP mapping defined in
object csqCosToDscpDscp.
If this object is trustCoS(2), then the DSCP assigned
to the packet is the layer2 CoS of the packet mapped to a
DSCP by the CoS-to-DSCP mapping defined in object
csqCosToDscpDscp.
When this object is trustIpPrec(3), a DSCP is assigned to
an IP packet according to the IP-Precedence-to-DSCP mapping
defined by the values contained in csqIpPrecToDscpTable. For
non-IP packets, trustIpPrec(3) has identical behavior as
trustCoS(2).
When this object is trustDscp(4), the DSCP contained in an IP
packet is trusted as being the correct value to assign to it.
For non-IP packets, trustDscp(4) has identical behavior as
trustCoS(2).
