HP Networking – MSR
The smallest HP router ex H3C MSR is really cool and cheap device. Comparing to competitors new HP devices are really competitive. A series is the highest class for providers. Class E is Enterprise. Parameters makes those equipements a very good choice.
One idea is really cool. Some HP routers contains USB port, but it is not only for flash memory 
It is possible to connect USB HSDPA modem for example. We get “cellular” interface in configuration and after clearing PIN on SIM-card and setting up dialer we have additional data trunk. Let’s say this is the best backup option on the market. Superb option for small oficess, home or backup for any office.
Simple and great idea.
Dial peer selection
Sometimes there is a need to configure more complicated configuration for incoming or outgouing calls. It’s good to remember what is an order of dial-peer’s selection by matching epcific elements. So it selects as below:
1. incoming called-address
2. answer-address
3. destination-pattern
4. voice-port
In the case of some issues start debug remembering that it is enough for gateway to match one of those elements.
Business divorce
I have been watching how things go since the end of Cisco and HP allince has became a fact.
After a few doubts I think more and more it would be a very interesting future. Very interesting for IT market. Even more after aquisition of 3COM by HP.
Why? Well the truth is that HP with entire past portfolio wasn’t a comparable competitor to Cisco. At those times when big companies grow in many cases by merges and aquistions it looks normal procedure to be strong and valuable in specific market. Of course today, aquisition is not 100% sure, but as many I wonder what product from both sides will be developed and what not.
From my point of view I am most curios about IP telephony – will it go to develop 3COM solutions separately or will be merged to HP ONE? What will be better from switches, security and wireless. Colubris technology is really cool, security I don’t know a lot but opinions let’s me thing Tipping Point will be one of diamonds in the crown.
Big question is: product to be developed further will be chosen because of their advantages or there will be more inside “fight” to force products, not always the best.
CCNA at last passed
After long time since I started Cisco certification finally I passed CCNA. Well I tried to pass it as I remember 3 years ago, but because of some issues and a lot of work, lack of knowledge I failed.
Working a lot at voice field I have been passing voice exams with no problems and to make that all voice exams have sense I needed CCNA. Practice is not so bad as many people thinks, but all those details and exact numbers. Many questions was for me only possible to solve on logical thinking.
However I’m almost 100% involved in voice so it left me only QoS to become CCVP. It looks like I certify from the end to the begining.
Finally NAS
After some long searching I found the best solution to reactivate old HP’s Vectra e-pc (PIII 866MHz 256MB). As a standard one disk PC it is nothing special, but because of usage power supply as notebook it was perfect for home server. I changed fan. I was tryiing with astlinux on CF, but there is kind of bug that after long time system stucks.
I tried also 5GB hard drive with CF interface (is it Microdrive?) with Centos 5 and Asterisk for my VoIP. It died too.
It is better to separate home file server from home ip-pbx.
I visited freenas.org for curiosity and realised that there has been prepared FreeNAS distro for flash. Easy, friendly and works fine. It is perfect for small, quiet, home NAS. That e-pc can work only with 2 PATA drives and I use both one for 2.5″ 60GB drive and IDE-CF flash drive with FreeNAS.
If this configuration will be OK as home server I will try another useful ideas:
- system booted from USB – even version 1.1 will be enough
- another real hard disk – maybe 3.5″ 500MB or more – big question regarding generated noise
- print server – should be easy
- UPnP server for my Samsung DLNA compatible LCD TV
All that looks promising with read/write throughput between 48Mb/s and 64Mb/s on 100Mb/s LAN. In my opinion good enough for test before going to 1Gb LAN to transport HD movies.
New Year test ride
I decided to ride my bike today. It was snowing all night long, so it was perfect time to test my still not used winter tires with metal spikes.
Because of snow – fluff snow, I didn’t notice any difference to standard tires. The best control is during riding through frozen hard ice.
By the way I was not riding my treking bike by MTB – Radon ZR Team.
happy biker
X-mas this year where really really successful. My family had a huge problem with a present for me. After my bike was stolen I decided my new one will not be used to ride to work. It will be only for bike marathons and any other competiotns. I was looking for some used bike from second hand to ride work.
There came my mather-in-law with an idea finally with my parents and wife with help of my cousin who sells bikes I received not used but brand new trekking bike. Enough to ride to work and is not fancy.
Good final of the story after my bike was stolen is that my employer prepared one garage place for closed bike cage. Hurrray. Because there is many coleagues that ride bike to work, it made happy many of us.
From MSN to DDI
I really hate when customer plays unfair – doing big change in services without notice. It was this time with approximatelly 30 remote offices each with 2 bri interfaces.
In the half of them we met an issue. Conections wasn’t established properly. After searches solution was to reconfigure bri interfaces as below
isdn tei-negotiation first-call
isdn tei-negotiation power
isdn tei-negotiation powerup
isdn static-tei 0
Important: clear interface
CCIE Voice Lab
I saw a scheme how the lab looks like for CCIE Voice Lab exam. At least it is easier to learn build something similar to test, learn and troubleshoot most common issues and implementation tasks.
All looks clear except new version contains Cisco Presence – new to me – never implemented, never supported – yet. Secondary I wonder how important is Exchange server during lab exam. I hope it is just a tool to check some functionalities.
Incoming Fax
I checked how that works. For now only infoming faxes. Looks fine, except one disadvantage – e-mailing fax as tiff is not got option it is always a low quality.
