This read-only TruthValue object indicates whether VPI values entering this VSI logical interface get translated at the far end of the link, which can be a sign that the link is carrying a tunnel. An administrator uses this to understand whether the VPI numbering scheme is consistent end-to-end or is being remapped, which matters when tracing a cross-connect across the link. For example, if vsiLogicalIfVpiTranslated is true, the admin knows the VPI seen locally will not directly match the VPI in use at the remote end of that link.
