I both used fw marks and route realm marks and = that worked in both occasions. serge. -----Original Message----- From: David Coello [mailto:dcoello@quarkinside.com] Sent: Wednesday, December 11, 2002 7:16 PM To: lartc@mailman.ds9a.nl Subject: Re: [LARTC] Bandwidth by port Hi But why the code of above doesn=B4t work?
