I personally did "disable vlan Xyz" instead of "delete vlan Xyz"
on Extreme Network... which proceeded to disable all the ports where
the VLAN was present...<br>
<br>
Good thing it was a (local) remote pop and not on the core.<br>

<div>Have you ever unintentionally crashed a device by running a
perfectly innocuous command?</div>
<div>1. Crashed a 6500/Sup2 by typing "show ip dhcp binding".</div>
<div>2. "clear interface XXX" on a Nexus 7K triggered a
cascading/undocument Sev1 bug that caused two linecards to
crash and reload, and take down about two dozen buildings on
campus at the .edu where I used to work.</div>
<div>3. For those that ever had the misfortune of using early
versions of the "bcc" command shell* on Bay Networks routers,
which was intended to make the CLI make look and feel more
like a Cisco router, you have my condolences. One would
reasonably expect "delete ?" to respond with a list of valid
arguments for that command. Instead, it deleted, well...
everything, and prompted an on-site restore/reboot.</div>

<div>BCC originally stood for "Bay Command Console", but we
joked that it really stood for "Blatant Cisco Clone".</div>

I'd like to start a thread about the most famous and
widespread Internet<br>
operational issues, outages or implementation
incompatibilities you<br>
have seen.<br>
<br>
Which examples would make up your top three?<br>
<br>
To get things started, I'd suggest the AS 7007 event is
perhaps the<br>
most notorious and likely to top many lists including mine.
So if<br>
that is one for you I'm asking for just two more.<br>
<br>
I'm particularly interested in this as the first step in
developing a<br>
future NANOG session. I'd be particularly interested in any
issues<br>
that also identify key individuals that might still be around
and<br>
interested in participating in a retrospective. I already
have someone<br>
that is willing to talk about AS 7007, which shouldn't be hard
to guess<br>
who.<br>
<br>
Thanks in advance for your suggestions,<br>
<br>
John<br>
