A detailed look at the Big, Hot and Heavy Ethernet Switches with a large crew to talk about their practical experiences on design, selection and performance of Cisco Nexus switches. The result ? We don’t think the Nexus switches are very exciting, HP Flex10 modules are a problem, and so much more.
Due to people commitments we recorded a double length show which will be released in two parts. This is Part 1 and Part 2 will be released next weekend.
VSS & vPC – the real experience
We started with a look at the differences between Cisco’s Virtual Switching System (VSS) and their Virtual Port Channel (vPC) implementation of Multi-Chassis Etherchannel and what our preferences are for choosing and implementing. We like vPC both from a design and implementation perspectives but our experiences of VSS have been very poor and we don’t choose to use it in the Data Centre. In practical way we don’t like the way that VSS is conceptually the same as a stackable switch.
We also don’t have much time on the Catalyst 4500 because they aren’t used in our designs. Also, there are too many modules and Supervisors, and the technology is confusing. The lack of architecture information is poor.
Cisco Fabric Extender switches
We had a short look at the QoS implementation on the Cat6500, and expressed our dissatisfaction with the configuration and consistency of the implementation and some surprising tips on how to solve the QoS problem.
We discuss the use of Service Modules in the C6500 chassis and our experiences.
