Priscilla, Thanks for posting an interesting "case". I am planning on testing your scenarios hands-on during the weekend and post the results by Monday.
You may have already seen it, but I'd suggest that you visit the following CCO URL for more information on the Serial Interface status you're trying to clarify. http://www.cisco.com/warp/public/112/chapter15.htm#showinter Hth, Angel MCSE, CCNP-R&S, CCNP-WAN -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Priscilla Oppenheimer Sent: Thursday, June 20, 2002 5:34 PM To: [EMAIL PROTECTED] Subject: serial interface down/down or up/down [7:47101] Hi Group Study, While writing some questions for a practice test, I found myself questioning what I thought was the right answer. Here's the scenario: A Cisco router serial interface is correctly connected with a good V.35 cable to the data port on the DSU side of a CSU/DSU. The CSU/DSU has been misconfigured for the framing method (SF instead of ESF). The framing doesn't match what the provider is using. (The question refers to a CSU/DSU that is external to the router, not one that is built into the router.) Will the Cisco router serial interface be down/down or up/down? And, would the answer be any different if the question has to do with misconfiguring the encoding (AMI versus B8ZS)? If you have real-world experience with this, that would help. I have read the Cisco documentation and the troubleshooting charts, etc. Thanks Priscilla ________________________ Priscilla Oppenheimer http://www.priscilla.com Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=47138&t=47101 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
