I guess a key part to studying for CCIE is to understand what devices and IOS versions you will be tested on in the lab. Thanks to Cisco they let you know this information; Version 4 makes use of; 1841 series routers – IOS 12.4(T) – Advanced Enterprise Services 3825 series routers – IOS 12.4(T) – …

The CCIE Routing & Switching blueprint can be see below, the topics that I have covered as part of my study will have hyper-links off to the corresponding post. This is very much work in progress so therefore is far from complete. [table id=4 /]

So I have started looking at CCIE study and have been looking around to see what books and useful material exists out there. To begin with this list may be sort but as I progress I am sure that the list will increase. I look to have been very lucky in that a number of these books (and more) my Dad …

So after putting off doing the TSHOOT (642-832) exam, my final one to gain CCNP, I finally booked and did it. In the end I found it relatively straight forward gaining a massive 100% (1000/1000). It was actually quite an enjoyable exam (if that is possible), consisting of a number of ‘trouble …

Network Management Systems (NMS) So what’s it all about and how can it help me? Well as a bit of a history lesson in the early 1980s saw a tremendous expansion in the area of network deployment. As companies realised the cost benefits and productivity gains created by network technology, they began …

I have recently been building a number of devices as well as reconfiguring some old devices form stores. One of the issues in reusing pre-configured devices is that you may not know the password. Easy you say if these are Cisco devices just following the password recovery procedure by going into …

I changed jobs 2 years ago and focus more on routing and switching (NMS/OSS now sits more on the hobby list) now so I decided to start up again on the Cisco certifications (thinking of others as well). This year I have completed CCDA, CCDP and just need to pass TSHOOT to gain full CCNP. I have …

During the building and configuration of a number of brand spanking new Cisco 6509’s with Sup720-3C I decided to convert them to VSS mode before updating the IOS (mainly due to laziness and only having console access). The conversion worked a treat however when I can to upgrade the IOS with ISSU I …

I have been meaning to put this one up for a while now, the end of April has reminded me of the April fools RFCs. Yes it is a bit sad to look forward to the April fool RFC – my favourite might well be the IP over Avian Carrier ones. I do think it is worth putting this one up again, especially on the …

During some recent work we discovered a very interesting bug with Cisco 6500 and specifically their WS-X6708-10GE and WS-X6716-10GE cards. When installing the cards into 6509 or 6513 chassis it can cause an existing module to reload so if you happen to have chosen slot 9-13 you have a issue. The 8th …
