Subject: Packetlost when "tc qdisc del dev eth0 root"
Date: Tue, 15 Jan 2008 14:10:47 +0300	[thread overview]
Message-ID: <478C94B7.3070503@bigtelecom.ru> (raw)

Hello all. Have packetlost when do "tc qdisc del dev eth0 root".

look:

slavon ~ # ping -f 87.255.1.134
PING 87.255.1.134 (87.255.1.134) 56(84) bytes of data.
.
.....................................................................................................................................................................................................................................................................
.
--- 87.255.1.134 ping statistics ---
60811 packets transmitted, 60544 received, 0% packet loss, time 39528ms
rtt min/avg/max/mdev = 0.203/0.579/3227.655/13.124 ms, pipe 219, 
ipg/ewma 0.650/2.197 ms

Its normal?
Maybe if tc do changes - need create second queue (hash of rules or how 
you named it?) and do changes at it. Then replace old queue rules by 
created new.
Logic -
1. Do snapshot
2. Do changes in shapshot
3. All new packets go to snapshot
4. If old queue not have packets - delete it.
5. Snapshot its default.

Thanks for answers.
Slavon.
