Creating port-channels between Core – Edge … I had this blog post in my drafts section for a week, and then Scott Lowe – bless his cotton socks – beat me to it with a typically well-written post on ostensibly the same topic. So I’ll point you to his post, because it gets the idea across in a coherent fashion. I’ll make an effort, however, to get some more interesting switch config articles about before the Christmas break.
I was making some port-channels between one of our MDS 9513 director switches and a 9124e edge and managed to add the interfaces to the wrong port-channel. Here’re the basic steps on the 9124e end that I took to rectify the issue. I’ve created a pdf file which, while inconvenient, solves the problems related to both my wordpress skills and the age of the theme I use. That is, a 4 page doc was going to look pretty ugly if I tried to insert it in-line. I apologise in advance for the inconvenience you will no doubt experience.
