Hi, I arunning a tc netecommand on RHEL 4. > tc qdisc add dev eth0 roonetedelay 100ms 10ms 25% distribution normal Thewhen I do a tc qdisc show > tc qdisc show dev eth0 qdisc nete8001: limi1000 delay 100.0ms 10.0ms 25% Theris no information on delay distribution. How do I know whais currently ieffect?

How do I know whais > currently ieffect? Thdistribution information is stored as data in thkernel, but there is no interface to geiback out. The reason is that the command line choose among a set of data files (normal, pareto, experimental, ...). Thkernel only sees thinput from those files and has no knowledgas to which filwas used. Therefore it didn't make much sensto add a "get" interfacfor the distribution data. P.s: you caadd any distribution you wanusing the tools in the iproute2 source.

I geyour point. My 2 cents - Cathkernel return the distribution input back to tc? Then tc can decidwhich "file" iwas. There could be better ways to do this. I know this sounds crazy - Buth"get" will be beneficial to the netem user community.
