Cisco has a market cap of around $213,620,000,000.00. Revenue(ttm) is roughly 53,800,000,000.00. Cisco has no competitors even remotely close to this scale. It still has an operating margin(ttm) over 20%. It's stock closed at a 52 week high today. If Cisco loses 90% of its revenue it may still be bigger than what's left of Juniper after pieces of it and Aruba Networks are paired away in the joining inside HPE.
So you assert they knock off say 5,000-6,000 of 90,000 and are somehow left with 90,000, and having already told the street they only have 20-30% of the billion dollar charge for layoffs left over and you think they're going to layoff half the company and blindly shut down products rather than spin them out when they can't even keep things stable without such an insane shock, and you can't even offer the slightest speculation about why this would make sense even to someone who is insane? I call shenanigans.
Unless the stock does a Chambers and enter the teens yet again you'll have a smaller layoff announced by February and another announcement of layoffs under 10,000 by the end of the fiscal year. People on this site have discussed selling a golden goose or two over the years but Cisco doesn't really have a particularly valuable piece that works better on its own.
