Change Control - FAIL

Thu, 02 Oct 2008 23:24:36 +0000
Failure. Every network engineer will have a project or change control that, for whatever reason, fails.  Some failures are spectacular - you turn up a new link, bring up the routing protocol, and then the core crashes so hard, the lights dim in the data center.  The industry term for these sorts of failures is ...]

old habit

Today I recalled my old habit in configuring the routers. And today as well, I am using that habit for my home lab
access.

What old habit did I have? Configuring the router using notepad and pasted it to the router. Is it a 'bad' habit
or a 'good' habit? I have no idea!

During my work at various clients (particularly in Australia), I must carry out the router configuraion that way.
Whay is that so? To save time! When a customer request a replacement or a new site setup, most of the time the router
is not yet arrived in the office. Thus, to save time, I configure the router based on my best knowledge on the IOS,
chasis, modules, etc. Then I drafted out the basic configuration for connectivity then build the config from that
point on using all 'imagination' in my head on whether this command would do good once pasted or it will wreck havoc
in the production later. To make things worst, 'usually', the router (or even switch) only transits my office area
for around 4 hours. Thus within that 4 hour, I must be able to configured it in the 'full config' and ship it to the
customer in the same day. I would be lucky to have the router arrived at 5pm, but that means I must ship it before
10am the next working day. That means only 2 hours instead of 4 hour 'transit'.

During that period, there was no such thing called dynamips or in-kind. I must really knock on my head in order to
realized whether the config would work or not (not should!).

As of today, I have a poor Internet connection to home's (dynamips) lab. So, to save time I drafted out the
config, verify it that it would (and should!) work and once I arrived home: pasted it and compared it against the
correct answer. I have a quick glimpse on some answers that I have no idea what it asked. More than 90% of the
question is quite clear for me. Only minor (or silly???) misunderstanding in those 10% that might dragged me down
during my next lab attempt.

In the last two days, I have used extensive full-blown dynagen management. It is a very nice tool and could have
been tweaked for more dynamips options. All-in-all, I already have some idea to develop my own dynamips management
console (I will tell you all later once I got my CCIE number, ok? ;) )

It turned out that my answer so far is able to reach fair amount of correctness (I have not really drill the
details, maybe tonight). I am surprised with the result (and happy of course!)

Now the rest remains in the day of the lab next Monday. I will do my best to pass this one this time and earn the
number that I deserve (and have been desperately waiting on).
