If I use the Perf Toolkit option 32 History Data Files does the CPU column represent total CPU usage (IFL1%+IFL2%+IFL3%) or average CPU usage (IFL1%+IFL2%+IFL3%/3)? I can't find any doc on that particular screen (FCX195)...

Lee, if you point the 3270 cursor at the perfkit column heading you're interested in and hit PF1, Perfkit will show you a pop-up window of the definition of the columnthat's how Bill got the little window he showed in his note.

Duplicate IPs on VSWITCHes - Feature or Defect
Greetings all, We've been pulling our hair out for several days trying to figure out a networking issue involving VSWITCHes. A server (LNXA1) attached to VSWITCHA on VMSYSA can connect to a server (LNXB1) attached to VSWITCHB on VMSYSB but a server (LNXC1) attached to VSWITCHC on VMSYSC cannot. We moved LNXC1 to VSWITCHA on VMSYSA and it worked. All on the same subnet, BTW. Unbeknownst to us, a server (LNXC2) had an interface on VSWITCHC that used the same IP as LNXA1. It couldn't be registered to the outside network because it was already being used, yet it was still registered to VSWITCHC. Hence, anyone else on VSWITCHC would try to connect to LNXC2 when it in fact was trying to connect to LNXA1. Q VSWITCH VSWITCHC DETAILS shows the duplicate IP, identifiable by the Local designation under the list of unicast IP address(es). The VSWITCH is able to detect the fact that this is a duplicate IP. Is this a feature or a defect? Should VSWITCHC drop the IP address when it identifies the duplicate situation? What would a real switch do?
