通過cdprs.php收集CDP資料，很容易改寫，實現寫入資料庫

/usr/share/doc/cdpr/examples/

$ find /usr/share/doc/cdpr/examples/
/usr/share/doc/cdpr/examples/
/usr/share/doc/cdpr/examples/cdprs
/usr/share/doc/cdpr/examples/cdprs/cdprs.cgi.gz
/usr/share/doc/cdpr/examples/cdprs/cdprs.php
/usr/share/doc/cdpr/examples/cdpr.conf
		

這個功能可以實現後自動繪製網路拓撲，分析收集的資料，然後通過Graphviz繪製網路拓撲圖。
