<p>Is there anyone here who either:</p>
<p>a) Hasn't done the vlan xxx instead of vlan add xxx?</p>
<p>or</p>
<p>b) Hasn't directly seen the vlan xxx instead of vlan add xxx done?</p>
<p>Or, if you're more of a systems person, haven't locked yourself out of a server due to a firewall change, or directly seen someone else do so?</p>
<p>Or, if you're a DBA, done an update to a database table and missed the where clause, overwriting every single record?</p>
<p>I'd consider these fairly common errors that almost everyone makes, once, and a fantastic way to evaluate someone's response under pressure. They're also fantastic teachable moments (once resolved) as to why certain company processes and procedures exist.</p>
<p>I'd probably be concerned if the same person made the same mistake more than once, though.</p>

<div dir="ltr">I just remember one of my mate told a story about one particular CCIE doing "switchport trunk allowed vlan xxx" instead of "switchport trunk allowed vlan add xxx" and caused an outage. Companies losing money (according to him. It's a stock trading company). Though it's weird they needed more time to address where the issue was. </div>
