Robin Padilla vs. Richard Gomez (a classic one)
Of course, showbusiness is a world of intrigues, but later on, we should all reconciliate with each other. Matatanda na tayo eh. We already know what's wrong and what's right.

Simplify network design
Going back to my usual stuff, I found out this link.
Ciscoweb tools: Designer
It's a pretty neat tool, which I guess has been available for quite sometime, which helps us in planning and choosing the right equipment, design and the deployment for our equipment.
It asks us, for example, the number of users, how many branch offices(if applicable), if there will be remote users, what kind of connectivity do we plan to use, e.g. Private Leased WAN or the internet, the security you'll use, the technology we are going to use e.g. VoIP, storage, proprietary applications, etc... all that stuff. And you can choose to answer the questions in the form of a simple, radio button type of interview.
I usually design for medium sized to enterprise networks, having those in mind, I came up with this.
Click on the image above to see the picture clearly.
Pretty neat eh? Try this one out, and see different results for different network scenarios and needs. Enjoy!

Cisco IOS Hidden Tools
Cisco IOS hidden tools
Hello there,
Just a quick overview over a couple of cisco hidden command useful in certain circumstances
1. ttcp
ttcp is only available on routers/layer 3 switches
For those familiar with iperf, ttcp is a kinda”ish” iperf
Start ttcp on one router in point 2 point scenario and ttcp on the other endpoint. One router will be in receiving mode, while the other will be in sending mode… running the command is quite straight forward, thus I will not demonstrate it here.
2. test crash
Ok this used to be hidden, but isn’t in newer IOS version. Test crash allows to simulate a crash.. so you came to the office one morning and found your switch dead… not log, not knowing what happened. test crash can help you dig into the problem by simulating the crash
3. test transmit
This is a very cool feature. You can simulate traffic to interfaces, using specific encapsulations and protocols…
4. ip route profile and show ip route profile
Used in conjonction, this “debug” command enables you to see route fluctuation.
5. csim start “number”
This emulates a voice call to the specified number… practical for VoIP testing environment.
6. show controller switch
Need to get a quick overview on your switch traffic stats. Suspect a congestion network? show controller switch will give you the quick heads up on where you stand
7. debug ip osfp monitor
This command enables you to monitor the OSPF SPF process
8. ip-con 2 con
Available on cisco 7500… it enables you to enter the VIP console to execute VIP commands on VIP boards
9. ip osfp interface retry
Back to OSPF (the coolest routing protocol), by default OSPF pools retry on the interface 10 times… having too much fluctuation of states on the interface of your router? increase the pooling period.
10. show region
Displays how the memory is partitioned on the device
