This is ideal when you are studying for your CCNA, CCNP, CCSP, CCIP or any other Cisco certificat Wed, 18 Aug 2010 21:03:26 +0200 /en/home/2010/08/18/44-gns3vault-growing-strong http://www.renemolenaar.nl/en/home?task=feed&type=rss2&id=44 /en/home/2010/08/17/43-ccie-importance-of-the-doccd /en/home/2010/08/17/43-ccie-importance-of-the-doccd#comment Rene Molenaar Hello all, In case you are studying for you CCIE and are not sure what the DOC CD is about, and how importance it is...please check out this great link explaining it all: Tue, 17 Aug 2010 20:21:08 +0200 /en/home/2010/08/17/43-ccie-importance-of-the-doccd http://www.renemolenaar.nl/en/home?task=feed&type=rss2&id=43 /en/home/2010/08/17/42-ios-features-you-should-disable-or-restrict /en/home/2010/08/17/42-ios-features-you-should-disable-or-restrict#comment Rene Molenaar I found a nice little overview of some IOS features that are possible on a Cisco router, some of them are enabled by default and possibly a security risk..it's a good idea to check them out and perhaps disable them on your network!
