This attribute specifies whether or not explore frames received from
SourceRouteBridge ports will be sent to the SRTB-8209 translation or
the encapsulated SourceRouteBridge logic. This option is used only
when both the TbsrBridgePort and the SrtbBridgePort are provisioned
and enabled.
A value of Xlate implies that the explore frames will be sent to the Srtb
translation logic and a value of Encap implies that the frames will be
sent to the Encapsulated source route bridging logic.
