The value of sapTlsDhcpMsapTrigger specifies whether
the receipt of DHCP trigger packets on this VPLS SAP
with a sapSubType value of 'capture' will result in
a Radius authentication that will provide a service
context and the creation of a SAP with a sapSubType
value of 'managed'.
An attempt to set the value sapTlsDhcpMsapTrigger to
'true' on a SAP with sapSubType other than 'capture'
will return an 'inconsistentValue' error.
