...is not Tariffs.
It is immigration policy (H1B expirations, deportations and fear). Cisco is shifting to India. If you doubt this, look at the internal directory.
It is the failed RTO. Cisco's bread and butter is failing.
Cisco sells network gear (think "switchports"). How many switchports do you have at home? 5 maybe? Are they Cisco? probably not.
But I have a Linksys, that's Cisco, right?
Nope. Cisco sold Linksys to Belkin in 2013 and Foxconn bought them. Linksys is a Chinese company. The Linksys fiasco is a good example of what is going on now, poor management decisions.
Offices are empty and the ones that are being refurbished are not putting Cisco switches in. HPE, Aruba, Juniper, Arista, Huawei, Palo Alto, Fortinet, are all in play.
Juniper and Aruba are being chosen for wireless which, let's face it, is how you connect. (when was the last time you plugged a cable into your laptop?)
But the biggest threat is Cisco ELT chasing the shiny AI object over a cliff.
to be clear Cisco is not going anywhere but they are a shell of their former self. CCIE used to be a golden ticket, now it's a literal joke.
