This article has an error:
“The 90 sets the outbound bandwidth limit on the port to 90 percent of the port speed. Since this is a 100-Mb port, this should limit the outbound traffic from the port to 10 Mb.”
90% of 100 Mb is 90 Mb. If you want 10Mb, the line should read
srr-queue bandwidth limit 10
Strange that this article has been around for 5 years without correction… ?
