Drops usually occur when the inner qdisc is full during > enqueue, so they have quite opposite meanings. BTW, in your case the drops most likely occur because HFSC's default pfifo child qdiscs use the tx_queue_len of the device as their limit, which in case of vlan devices is zero (in that case 1 is used). So you can either increase the tx_queue_len of the vlan device or manually add child qdiscs with bigger limits. _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
