It would be easy enough for the delay simulator to enable/disable promiscuous mode. But it’s handy to bridge the pipes: traffic flows whether or not the delay simulation is enabled.

I am not sure how the WRED profiles are configured. I have hqos with 2 interfaces working in a bridge-domain and now want to enable WRED. My overall goal is to simulate the Linux tc "traffic control" application to run impairments such as delay and packet loss. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
