Cisco
continues to face ongoing attrition with many Cisco employees leaving for
competitors. RBC Capital Markets analyst Mark Sue released a research note this
week in which he writes “competitors seem to be hiring away Cisco engineers at
a high rate.” Sue claims that Cisco’s restructuring is causing rifts within
their organization.

Is your #network fragile?
Was thinkng this morning about comments ive gotten sometimes from customers about not wanting to risk their network with a second vendor.
That there was risk in doing so.
Here's my question im going to start asking back. If there is risk...Is that because your network is fragile? Why do you have a solution from a vendor that is so fragile..It cant interop? The risk then isnt with having two vendors...Its with the one you have.

With “display stp
vlan X” you can see the same result.
