can someone say "cantenna"?

Is this one of those AMD boxes?

yup AMD box.

Still trying to figure out how to stop the install of KB4056892.
I found a MS util to hide driver updates from windows, but it didn't seem to work.
Microsoft says that they are blocking that KB  from deployment, I have not followed up on that.
I did a system restore back to a time before the patch was installed, before I went to sleep.
will check on it after work today.

note
Microsoft has reports of some customers with AMD devices getting into an unbootable state after installing this KB.
To prevent this issue, Microsoft will temporarily pause Windows OS updates to devices with impacted AMD processors at this time.


This issue is resolved in KB4073290.  which does not exist,  trying to uninstall KB4056892.

when I insert USB drive into my PC, sometimes it is not recognized, when I go to reboot computer to see if that helps I get BSOD "Inaccessible boot device"
and PC doesn't boot anymore.  keeps happening more and more frequently.  happened last week, yesterday, and now again today.  End up having to a system restore to get the PC to boot again,   runs fine when usb devices are not recognized, other than the USB drive is not accessible.  usually only happens when or I seem to recognize this problem when I try to connect a USB device. Any ideas?

Fluke usually has some pretty good stuff, but pricey.

What's the budget???  a company I used to work for had wired marquee signs outside each conference room with built in calendar, and integrated into the exchange mail system.  one could walk bu see if the room was busy, check free time there, or at their desk,  nice but pricey

Box box stores like home depot here in US, have plug in home automation,  lamp plugs into little box, little box plugs into wall,  you can use an app to control the device.

biggest problem is security, many of these HA vendors are vulnerable,  ya wouldn't want your light turning on and off all night long.

I personally not messed with HA, due to vulnerabilities.

So my agency says, "work as much as you need to get your work done"
So my company says, "make sure you bill all your hours worked"
So my prime say, "all overtime must be pre-approved" (which they rarely do,as the Fed doesn't want to pay overtime)
and the Fed says "it's a federal offense to lie on your timesheet"

so what it one to do?

..."and Dean" says the Forescout boss "We need YOU to design that new military architecture"

with all those certs, the CA private keys are really really important, will have to devise a way to protect the CA server, without hindering production, eg. daily cert generation.

GL with IPv4 in China... and probably all the Asia-pacific area.

That's a Microsoft MAC address, so the MAC given for the LACP is likely software-configured to override the physical MAC addresses on the server.

like I said., device ID

i've seen stuff like this when I do a 'show cdp neigh' and Cisco phones are connected.
probably just a device ID.

I've seen VRF's, ethernet's, port channels, BVI's as of recent.   Bundle interfaces I have no clue

What does the OTDR say when you test the fiber cable?

there are also come cisco comannds ( if these are Cisco ) to identify power on the transceivers.
I forge the commands tho.

DWDM is Dense Wavelength Division Multiplexing.  "Dense" because it packs wavelengths closer together than previous wavelength division multiplexing methods.

Intuitively, a wavelength can be thought of as a particular 'color'.  Many colors can be passed down a single fiber and then separated out at the receiving end back into its constituent colors.  Each of those can in turn can be converted back into a digital signal.

The boards used at each end of a DWDM link are known as 'transponders', which each converting a signal from normal 'gray' optics into the specific color for the given channel.  Today, most transponders are 'tunable', meaning that a single board can generate any necessary given color under software control.

DWDM is used primarily in high-capacity long-haul networks.  For shorter distances, the cost of the fiber is lower, so DWDM is not cost effective.  Routers or switches are normally connected to the transponders and the DWDM link is transparent to those network nodes.

Been doing some Cisco ASR 9K training off some video's from Youtube,
Man that beast is in a whole other universe. 
It's like forget most of what you knew command wise and start re-learning.
