I restarted the queues to clear the counts and then ping'ed an unused IP address on the local subnet and counted the unanswered arp requests using tcpdump. I then used tc to show the queue counts and saw the respective counts in the default queue. I changed the default queue and perform the test again and saw the count appear in the new default queue. I'm pretty sure the counts in the default queue were arp requests. >> All the literature I've seen only covers tc filters dealing with the >> protocol IP.

But it wasn't so simple. I'm really having the opposite problem. I'm trying not to shape arps. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Damion de Soto - Software Engineer email: [EMAIL PROTECTED] SnapGear - A CyberGuard Company --- ph: +61 7 3435 2809 | Custom Embedded Solutions fax: +61 7 3891 3630 | and Security Appliances web: http://www.snapgear.com ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ --- Free Embedded Linux Distro at http://www.snapgear.org --- _______________________________________________ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
