It\u2019s been about a year and a half since I asked the question in this blog, \u201cIs the Cisco 6500 Series invincible?\u201d I believe enough time has passed and that I should revisit that question \u2014 especially since people in the industry have been talking, tweeting and writing about the demise of the venerable Catalyst 6500 chassis family for years.\u00a0\nBut don\u2019t worry, the King is not dead because Cisco is having none of that!\u00a0\n+ Also on Network World:\u00a04 resources to find free Cisco skills and certification labs\u00a0+\nAside from being a major revenue stream for Cisco, the 6500 chassis family remains a solid platform that the company has made extensible by creating the Catalyst 6800 family.\u00a0\nThe Catalyst 6800 family features:\u00a0\n\n6807 chassis \u2014 The blade is compatible with the 6500 and upgradeable to 6 terabits per second (Tbps). The network switch fabric supervisor 6T integrates a 6-terabit crossbar switch fabric that enables high performance on the Cisco Catalyst 6807-XL Chassis when in active-standby mode. The 8 port 40 gigabits per second (Gbps) blade (C6800-8P40G\/XL) serves a variety of high-bandwidth needs for the next-generation enterprise so far.\u00a0The published maximum is 11.4 Tbps and 440 Gbps\/slot \u2014 so there is plenty of room to grow.\n\n\n6880 mini-chassis \u2014 This consists of 220 Gbps slot capacity per port card and has 2 Tbps of switching capacity.\n\n\n6840-X Series Fixed Backbone Switch \u2014 I would consider this a mini-6500 with a sup2t \u2014 options range from 16 10-gig SFP+ all the way to 40 10-gig ports and 40-gig uplinks.\n\n\n6800ia \u2014 This gives network administrators the ability to look at buildings in a campus network as a single switch. This includes edge\/access layer switching \u2014 gigabit copper with or without PoE+ \u2014 and it\u2019s even stackable! Best of all, the 6800ia utilizes 6500\/6800 chassis as its core.\n\nCisco 6500 and 6800 families provide great options\nAnd on top of all that, you can still work up a 6500E series configuration \u2014 it\u2019s not end of sale (EoS) yet.\u00a0What more could you ask for?\u00a0A powerful chassis line with a long history of robustness and success, allowing for a smooth transition to a switching system that encompasses core and edge.\nKeep in mind that one of the very good things about these two chassis families is that Cisco designed the 6800 to be a smooth transition from the 6500. The Sup2T and several port blades are compatible with both chassis. So, age doesn\u2019t necessarily need to play a major role in your decision \u2014 you have very good options either way.\nNo matter what your deciding factors are, you have some great options with the Cisco 6500 and 6800 Series. Take a hard look at what\u2019s most important for your technology infrastructure and remember, we can confirm, the King is not dead!
