Subject: Cisco 5000 undocumented feature

While working a Cat5000 bug with Cisco, they told me how to put a
switch into "enable engineer" mode.  In this undocumented mode, there
are many commands, some dangerous.  To enter the mode, type "enable
engineer" and supply the following password:

     xxxxx122224yyyyy

...where xxxxx is the entry-level password and yyyyy is the enable
password.  For this to work, you have to have an entry-level password,
which is overridden on our switches because we run TACACS.  I had to
disable TACACS to get it to work.  Also, you have to be physically
connected to the console port on the supervisor module.

In the special mode, there's a trace command that shows packet dumps.
I used "set trace ntp 7" to look for NTP packets.  "Set trace ntp 0"
turned it back off.
