Bricked..

22 09 2011

Both a 2950 switch, and a 2811 router (that one hurt!) in two days! Unbelievable.

Firstly, the switch – I used write erase, expecting this to effectively delete my startup configuration file, but it actually deleted the OS image file. D’oh! I am finding the 2900XL fine for my study needs so far, but will be buying a replacement 2950 on pay day.

The router wasn’t my fault – it went from being fine one day to having a non-working console port the next. Tried alternative rollover cable, a different router etc, and every other combination worked fine. Unfortunately, I hadn’t enabled Telnet / SSH access so although it was working (a show cdp neighbor showed it live and kicking), so it’s effectively bricked.

This was my only 2-ethernet port router and my DCE-DTE cable hadn’t arrived yet, so I ordered a Cisco 1605 from Ebay for £30. Looks OK, with two ethernet ports (not fast ethernet) and a Serial port – plenty of scope for messing around with routing protocols etc.

ICND2

15 09 2011

Decided to delay this exam from the original chosen date (had to delay once already, due to the pretty much emergency implementation of a project at work) of Tuesday, as I didn’t feel ready.

Managed to get an appointment at the same test centre but for tomorrow, Friday. Had a few extra days to study, and have finally got the Cisco switches and routers out again.

The bits I’m most concerned about are OSPF / EIGRP and Frame Relay, because I don’t and have never used them before, which makes it much harder to ‘get’ the concepts.

I’ve also lost my DCE/DTE cable, and didn’t give myself enough time to order a new one, so am winging it a little with no practise on PPP/HDLC too!

Will update here when I can, hopefully as a CCNA!

Thanks a bunch, Measure Up!

11 09 2011

So, got the ICND2 exam on Tuesday, and thought I’d buy the online practise tests from Measure UP as I’ve done for numerous exams previously.

Imagine my disappointment when I logged in to my “Learning Locker”, after having added the ICND2 practise tests to my Basket, when I saw that I had to download Silverlight to proceed. This is not compatible with iPad, iPhone or even the full blown Mac OSX.

The thing I liked most about Measure Up was the fact that I could access the practise tests from a number of platforms – my work desktop, laptop, iPad2 and even iPhone (although this was pushing the boundaries due to the screen size).

Now, I was forced to boot my PC just to write a complaint to them. I will be looking for alternatives now, but I fear that there may not be any. I’d quite possible rather go without than have my hand forced with regards the platform I use.

CAS Server move

3 08 2011

Have now migrated my CAS server to HQ – now, if my main link goes down it will still be accessible from inside the office, and a quick DNS change (lowered the TTL of the record) will sort external OWA / ActiveSync / OutlookAnywhere clients.
