Cisco Extended Functions - redundancy

Sat, 15 Jul 2006 00:36:02 +0000
When multiple Cisco Extended Functions are active within a Cisco CallManager cluster, the redundancy manager uses an algorithm to determine which Cisco Extended Functions service is active and which is the backup CEF. The Redundancy Manager uses the lowest IP address of the server that is running the CEF service as the active servicne. The remaining CEF ...]

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).

What had happened?

Welcome back to DC's CCIE blog!

Between the last blog and this one, I have left my CCIE lab for the time being.

Sadly, it is due to financial reason. I have another commitment on my table that I must attend. However, rest assured that my CCIE spirit is still there,
hibernated for the time being ;)

Several weeks back, I announced my next attempt to be in August this year. Sadly (again), it is now scheduled to be end of this year, around December.

Well folks, stay tuned for the next breaking news of my next battle of CCIE lab attempt. Meanwhile, I will be doing practices and some dynamips play
around ;)

How to receive logging/traps with Linux from your dynamips with syslog-ng/snmptrapd

Sat, 29 Nov 2008 18:06:42 +0000
What are traps and informs and is it possible to have a NMS (Network Managment System) on your Linux box to receive those messages? Cisco Works is also NMS, you might try this also, it’s possible to install it under VMWare, i had some trouble with 3.1 on Windows 2003 Server Enterprise SP2 though. Complaining ...]
