Hey Peter! Thanks so much for the response. I really appreciated it. While messing around a bit with the CLI, I also found out you can get the same results without going into the developer mode by typing the following:

This doesn't seem to give me as much information as I would have expected. Here's a summary of my overall concern with these switches: I have 2 cores at different data centers. Both cores have a pair of 5800AF-48Gs setup in an IRF configuration. There is one major difference between the two cores, one core runs 1211P01 and the other core system is running 1808P11. The 1808 core is currently registering 25-30% cpu load and the pings are very volitile by comparison to the 1211 core. The 1808 core recently replaced a set of 5800-24Gs that were running 1211P01 as well. The ping metrics have substantially changed and I am concerned it relates to the CPU overhead or even something thats misconfigured on the switch. This graph here illustrates the differences I am seeing in performance on the switch by comparison to the statistics I was pulling from the 5800-24G running 1211P01. Smokeping (the application forming the graph) is clearly showing that there is a significant "drift" being shown. The green dot represents the "average" ms but the darker shaded area is the spread of the pings. As you can see the spread varies quite a bit more.
Does anyone have any input on why this might be happening? Is it standard for a 5800AF-48G to be running 30% CPU with an IRF configruation? This switch really isn't doing much more than the 5800-24G that it replaced. There is an extra IRF link added to the mix and I've configred BFD MAD.
