```

### Description

```asn1
pwMplsExpBitsMode OBJECT-TYPE
SYNTAX INTEGER {outerTunnel(1), specifiedValue(2), serviceDependant(3)}
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"This object is set by the operator to determine the PW shim
label EXP bits. The value of outerTunnel(1) is used where
there is an outer tunnel -- pwMplsMplsType equals to
mplsTe(0) or mplsNonTe(1). Note that in this case, there
is no need to mark the PW label with the EXP bits, since the
PW label is not visible to the intermediate nodes.
If there is no outer tunnel, specifiedValue(2) SHOULD be used
to indicate that the value is specified by pwMplsExpBits.
Setting serviceDependant(3) indicates that the EXP bits are
set based on a rule that is implementation specific."
DEFVAL {outerTunnel}
