Yes, but why? For example, we just recently had an issue where some piece of gear was configured as auto negotiate. After a lot of work, it was determined that the Cisco routers we were using don't do auto negotiate well and had somehow gotten into the wrong duplex state.
We turned off auto and set speed and duplicity to fixed values. Made a huge difference. Huge. I'm thinking that networks bytes are far greater than payload bytes due to retries, etc. -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@bama.ua.edu] On Behalf Of Scott Rowe Sent: Monday, April 18, 2011 10:41 AM To: IBM-MAIN@bama.ua.edu Subject: Re: When is an OSA card too busy? So, this is a Gigabit OSA? If so, 100MB is close enough to theoretical maximum data rate that it's pretty safe to say it's maxed out.
