Majornetwork.net is now IPv6-enabled! I just forgot to ask for the AAAA record from my provider. Don’t always think that everything has to be hard!

Choosing Your Core Switches
When designing data center or campus LAN with Cisco products (see I made the point clear here immediately) a no-brainer solution is using Nexus 7000 switches in the core. There aren’t really many cases you can go wrong operationally with it in general-purpose data center or even campus environments. But, if you think they cost […]

Using dual-homed FEXes with Cisco Nexus 5000 switches presents some new issues for the network admins. One important feature is that the FEX port configuration needs to exist on the both N5ks.
