The full name of eNSP is Enterprise Network Simulation Platform, newly developed by Huawei. I downloaded it last week and tried it and found it was a perfect solution for the HCIE book. By the way, the book has 2691 pages, you can’t finish it without passion on network.
Before eNSP, I was frustrated that I didn’t have good network simulator to improve my networking skill. I tried Cisco Packet Tracer, but it was only a simple tool for CCNA. When I tried to establish profound networking lab, it showed me that I couldn’t type some commands. The feeling was bad when I wanted to use some functions, it turned out the simulator couldn’t do it. By the way, the CPT’s web GUI wasn’t bad, that’s it.
Later, I tried to use Cisco CIM. The CIM I used was too old for the current networking technology. Why should I learn technology out of fashion? Technology was different from literature. Old literature was always good, but this wasn’t work for technology, especially network technology.
There was also GNS3. With this simulator I could use router such as C1700, C2691, C3640, C7200. To be honest, router part was good, but the software was running out of management switch, which sounded horrible to me. By the way, several routers running at the same time would exhaust my PC to death. Though I calculated Idle PC value, serious improvement wasn’t available.
A Chinese guy made a DynamipsGUI simulator, I tried it once and then ignored it, not a good simulator.
One month ago, I found Boson Netsim 8.0. The simulator was for CCNA and CCNP lab. It included detailed instructions and topology, all you had to do was to follow it. It’s the best simulator until I met eNSP and HCIE. If I had time, I would practise it to improve my Cisco networking skill.
When I first used eNSP, I wasn’t accustomed to Huawei equipment. After several hours, I found it’s the same as Cisco, after all, networking technology was the same and it didn’t matter there was a little difference between networking equipment vendors such as Huawei and Cisco. By the way, Juniper is a good company, it’s a pity I only used its firewall.
Now I got used to Huawei networking equipment. Cisco’s enable, configure terminal, configure interface, show, no, etc. Huawei’s system-view, interface, display, undo etc. The difference doesn’t bother me now. I like Huawei’s save command than copy running-config startup-config.
Learn HCIE with eNSP to make myself an excellent networking engineer, maybe an excellent networking architect in future. Learn English to native level. Those are my two dreams. I listened to Schwarzenegger’s speech several days ago and was impressed by his words, “Pain means progress. You have your dream, try it, even you fail, so what?”
Struggle hard, I don’t want that I have nothing to be proud of to tell my future grandchildren.
