Hi, I am using CBQ on Linux (kernet 2.2.16) and I want set priority and separate channel for ICMP packets. I need it, becouse if CBQ class is full, pings and traceroute are slow. How to set up CBQ that pings and traceroute will be allways fast. But I don't know how to set up filters. My current configuration is (please see comments inline): # -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= # -- Starting -- tc qdisc add dev eth0 root handle 10: cbq bandwidth 10Mbit avpkt 1000 \ cell 8 tc class add dev eth0 parent 10:0 classid 10:1 cbq bandwidth 10Mbit\ rate 10Mbit allot 1514 cell 8 weight 1Mbit prio 8 maxburst 20 avpkt 1000 tc class add dev eth0 parent 10:1 classid 10:128 cbq bandwidth 10Mbit \ rate 64Kbit allot 1514 cell 8 weight 1Kbit prio 5 maxburst 20 avpkt \ 1000 bounded tc class add dev eth0 parent 10:128 classid 10:129 cbq bandwidth 64Kbit\ rate 6Kbit allot 1514 cell 8 weight 1Kbit prio 5 maxburst 20 avpkt 1000 # -- 1Kbit channel with highest priority 1 -- tc class add dev eth0 parent 10:128 classid 10:131 cbq bandwidth 64Kbit\ rate 10bps allot 1514 cell 8 weight 1Kbit prio 1 maxburst 20 avpkt 250 tc qdisc add dev eth0 parent 10:129 tbf rate 64Kbit buffer 10Kb/8 limit 15Kb tc qdisc add dev eth0 parent 10:131 tbf rate 1Kbit buffer 10Kb/8 limit 15Kb tc filter add dev eth0 parent 10:0 protocol ip prio 100 u32 match ip\ dst 62.168.36.12 flowid 10:129 # -- This is the filter for ICMP, but I do not know how to set up # -- 'match ip protocol 17 0xFF' tc filter add dev eth0 parent 10:0 protocol ip prio 100 u32 match ip\ protocol 17 0xFF flowid 10:131 # ^^^^^^^^^^ How to indentify ICMP packets here?? # -- End -- Many thanks Vladimir Vlach -- +=-=-=-=-=/ // /-=-=-=-=-=-=-=-=-+-=-=-=-=-=-+---------------------+ | / // / Vladimir VLACH > )))))))) | \/ |_ /\ |) /\ | |__ __ / // / Admin of ICQ.CZ > (((( \ | Age - 21| |\ \\ \/ // / http://www.icq.cz > \\\ 6 6 | Nick - Vladaman| | \ \\/ // / http://www.danet.cz > \C 7 | ICQ UIN# - 9511246| | \ V /V / email: vlach@icq.cz > \ _-) | Location - Brno[CZ]| +---\_/\_/-=---=---=---=---=---=-+-=- ) ( =-=+---------------------+ - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.rutgers.edu
