Hi All,
It would be appreciated if anyone using TC on Linux for shaping could please
help with an intermittent problem on an egress interface.
I'm seeing about ten per cent of packet loss for all classes at seemingly
quiet times and random parts of the day using about forty classes and
250Mbps. I've isolated it to the egress HTB qdisc.
Any TC experts out there have a spare minute please ? Any thoughts on the
RED qdisc ?
Thanks very much,
Chris
