From SYS$LIBRARY:LIB.REQ:
!*** MODULE $VCRPDEF ***
! +
!  VCRP - VAX Communication Request Packet
!
!  The VCRP is the data structure used to pass requests between VCMs.  A
!  single VCRP may traverse more than two VCMs.  Only the common fields
!  within the VCRP are defined here.  All layer-specific fields are defined
!  elsewhere.  The common VCRP function codes are also defined here.
!
!  CORRESPONDING CHANGES BEING MAY TO THE DCBE.
! -
!  Function codes used in the VCRP$L_FUNCTION field.  The function codes
!  are separated numerically by layer as follows:
!
!    0000-01FF Common function codes from the VCI functional specification
!    0200-02FF DLL Data Link function codes
!    0300-03FF NRL Network Routing function codes
!    0400-04FF TPL Transport function codes
!    0500-05FF SCL Session function codes
!    0600-06FF APP Application function codes

Perhaps looking at the VCRP$L_FUNCTION field (function codes are defined in
LIB.REQ), might provide some insight.  I only took a cursory glance at the
different fields in the VCRP, but perhaps there's something in there that
would identify which nodes are communicating as well.  Good luck,
