Re: A STP question
Give the man a prize. You are absolutely correct. Our 4th CEC does not need to be connected to Ethernet. I talked to Dave Whitney who owns STP and he indicated since the CEC is not the Primary, Backup, or Aribiter, it does not need an Ethernet source to get to NTP. ___ Jim Petersen MVS - Lead Systems Engineer Home Depot Technology Center 1300 Park Center Drive, Austin, TX 78753 www.homedepot.com email:[EMAIL PROTECTED] 512-977-2615 direct 210-977-2930 fax 210-859-9887 cell phone -Original Message- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Scott Rowe Sent: Tuesday, September 23, 2008 3:38 PM To: IBM-MAIN@BAMA.UA.EDU Subject: Re: A STP question >From what I know of STP, I would think you are OK, no connection needed on the 4th CEC.
