Note that this function requires dynamically allocated memory of size N * numNsePorts *
sizeof(UINT1) when copying page from one NSE to a different one. N is 9720 or 1080 in byte
and column mode respectively. numNsePorts is 12 or 32 for NSE-8G or NSE-20G device
respectively.
Getting active connection page number: nbcsStswGetPage
This function retrieves the active connection page of the switch for the specified device. In the
case of group, the buffer (
the case of a distributed system configuration, the page information of the remote SBS is obtained
from the in-band link header byte PAGE[1:0]. The in-band link controller on the remote SBS has
to be enabled for this API to function correctly.
