Have you experimented with L2,L3 or L2 policies? Does it send anything "useful" through the almost idle link? If so, what is it exactly? Do you have direct access to the clients or is it going through a proxy? Can you send just a few packet samples from the busy link? -- Giovanni Tirloni _______________________________________________ networking-discuss mailing list networking-discuss@opensolaris.org
