Hey Terry,
I would like to state for the record that every time I have done
this lab I have used PAgP regardless of what the DSG shows, you
would be correct in your assumption since the wording does state
"negotiate". If for some reason mode "on" is also OK I would like
to know why that would be.
I too am paranoid and over think the scenarios most of the time, so
I'm right there with you guys!
Steve

I've got the same problem for sure... last week in the bootcamp
Marko said I really need to quit over-thinking things. I spend a lot
of time worrying whether my solution is the 'right' one.

Thank Jay, nice to know it's not me. I'm more scared of the wording of
an exam question than I am of the technology they are asking about (or
the tech I think they are asking about). I've become pretty paranoid
over the last year or so. lol

I would read the 'manage one-way links' task as requiring
aggressive mode
since it will not actively take down a link without that option being
enabled.
I would also read that the task requires PAgP based on the wording
"can not
use an industry standard, but we must make sure these links can
negotiate
their setup"

Section 2.4
Configure any interfaces connecting the switches together to
appear as
one link to STP per neighbor.
If either of the interfaces is damaged, the switches should manage
one-way links. Do not use industry
standards, but make sure these links can negotiate their setup.
The task states that one-way links should be "managed" but the
solution guide states:
"Finally, turn on UDLD to manage the one-way link detection.
There's
no mention about anything
requiring aggressive mode, so that part is up to you."
I guess my question is one regarding wording. The task states that
the switches should "manage" one-way
links. The prescribed solution seems only informational (at best)
and
would do nothing to prevent Bridging-
Loops. Which I assume is what we are being asked to manage.
Additionally, the task states that we can not use an industry
standard, but we must make sure these links
can "negotiate their setup".
But the solution on page 43 states that we "end up either using PAgP
or just mode on"
I thought that mode "on" didn't allow negotiation, am I incorrect?
Any help/thoughts would be appreciated.
Terry
