From the 'what happens after keynotes go bad' file:

After 15 years, Cisco's Jayshree Ullal, SVP, Data Center, Switching & Services  is leaving. Ullal managed a $10 billion business at Cisco.

"Yes, I can confirm that after 15 years at Cisco, Jayshree has decided to leave the company to pursue other opportunities," a Cisco spokesperson wrote in an email to InternetNews.com. "At this time, Jayshree is in the process of exploring other opportunities and has not made any commitments."

Ullal also wrote a blog post on the Cisco data center blog in which she provided some highlights of her career, though not much in the way of reasons as to why she is leaving now.

Ullal will be replaced by John McCool who will assume Ullal's post alongside maintaining his current role of leading  Cisco's Campus Switching Systems Technology Group. McCool will be  reporting directly to Cisco CEO John Chambers.

Without reading too much into this executive shift, I think McCool's new responsibilities tie in nicely with Cisco's overall business consolidation effort. Frankly I don't understand why Campus Switching should sit under different leadership anyways so this move makes great sense.

Let's just hope for McCool's sake that if he ever takes the stage at a big IT conference, his presentation goes better than the one that Ullal recently did at Interop.
