@networkservice While upgrading switch, flash is big enough to hold two images, after changing bootvar & reload switch goes in rommon mode because it cannot extract new image due to lack of storage.

@timjclevenger @NetworkBrouhaha @nic972 Didn't we borrow TCP UDP port range with NAT?

#NeedleInATimestack has dropped in theatres and on Prime!One of the most memorable productions I have worked on,from (seriously) star studded cast to writer-director John Ridley to the fab crew.A riveting timey-wimey Sci-fi love story based on book by Robert Silverberg. Enjoy!

The youtube channel @Socratica is highly underrated and deserves more support IMO. Not only do they have great educational content and coding videos, but the way it is delivered is also exceptionally good. The #Python and #SQL videos by @ulkaM are superb.

@NWMichl Hiw about "reload in" test and "reload cancel". Its in your had to test and save reload.

@briankrebs Wondering if they lost both at IPv4 and IPv6 reachability to peering routers?

[briankrebs @briankrebs]

From trusted source: Person on FB recovery effort said the outage was from a routine BGP update gone wrong. But the update blocked remote users from reverting changes, and people with physical access didn't have network/logical access. So blocked at both ends from reversing it.

@NWMichl Cli scraping every hour is what we do. Use to do 15min for some commands but some switches with fex takes so long which timeout scripts.

[Krunal Shah @krunalshah]

@NWMichl We detach data collection from upgrade process meaning data is always collected at periodic interval and placed on flat file or sql database. Post upgrade you just need to compare data before and after.

@thedrunkneteng End of the day juniper makes bug free JUNOS software Arista had bug in EOS🤭

@nickrusso42518 Its like dict get() method

[Daily Python Tip 🐍🐧 @python_tip]

If you want to get home directory with #pathlib library, use

pathlib.Path.home()

Path('~') is not home but a folder named '~', e.g.

>>> p = Path('~/tmp')
>>> p.mkdir(parents=True)

creates a subfolder '~/tmp' in your current folder. (Please, be extra careful when deleting it)

@kochargurpreet This is great read. Pulling a show command from 28k devices every 15min is very ambitious. Have thought about using something that stays always connected? And you kind of pull show command using api layer?

[Krunal Shah @krunalshah]

@danieldibswe Python is going to be my choice and as network engineer would prefer to convert those acls to prefixlist.
