Collection of useful, relevant or inane places on the the Internets for 14 Mar 10:
- Cisco VNI – Visual Networking Index -Because is runs completely in Flash and uses so much graphics, the software is mostly unusable on my MacBook Pro (Core 2 Duo 2.93 Ghz, 8GB RAM) because it pegs the CPU.
Appears to be a highly branded exercise from Cisco to deliver a SpeedTest or similar uplink testing tool. WHY ?
Overmarketing from Cisco. Again. Simple, direct tools are what is needed. Not this grossly overdone marketing exercise. Fail.
- GuruPlug Server – I’m wondering if this is a good component for an IOS Lab.
- Quirks of the Cisco 6500 Sup720 Module Ports – Dr Peter Welcher – (who was blogging long before anyone else)
I think I have a love / hate relationship going with the Cisco 6500 Sup720-10G module ports. On the one hand, they’re darn handy and cost-effective. On the other hand, they represent one more set of one-off gotchas that make the whole 6500 complex. I won’t say unnecessarily complex, but definitely taxing to track the idiosynracies of, the capabilities and limitations of the various modules, etc. Bleeding edge technology (or what once was), cost effective, however it seems like it could all be a lot more user friendly. (Take QoS for example … but that’s another rant.)
FWIW, I agree, The Catalyst 6500 now has so many hacks, workarounds and kludges that it is difficult to use in high performance networks.
- Security industry faces attacks it cannot stop | ITworld -It’s not me, it’s you.
At the RSA Conference in San Francisco last week, security vendors pitched their next generation of security products, promising to protect customers from security threats in the cloud and on mobile devices. But what went largely unsaid was that the industry has failed to protect paying customers from some of today’s most pernicious threats.
IT Security has always been a failure, but, companies don’t yet see the value of increasing their “insurance premium” for IT Security. Nobody wins.
- Funny bug in Cisco Cat. 3750 12.2(50)SE – You’ve gotta see this to believe it. Awesome bug.
- Nortel: Corporate Information: Nortel On Nortel: IT Tools: Multicast Hammer –
Test and validate unicast and multicast configurations on your network with Multicast Hammer: an easy to use, Java-based testing tool.
Since a multicast server does not typically know anything about the clients that it is sending traffic to, tracing or troubleshooting an issue in a multicast environment can be very challenging. Nortel IT created Multicast Hammer to help overcome these limitations, and has used it as a testing tool for trials of multicast products.
Multiple instances of the Multicast Hammer tool can be placed in various points within your network, in either Server or Client configurations, and will log events and generate traffic as configured by you.
