Catalyst 6500 Speaks: Happy Birthday Sup720, Here’s To The Big 10

- March 31, 2013 - 7 Comments

Cat6k Happy BirthdayOr in IPv6 speak, you’re an “A”, for Awesome

Today Supervisor 720, the most widely deployed Catalyst 6500 Supervisor Engine, turns 10-years old.

Supervisor 720 was launched on March 31, 2003. It enabled me to be the first modular switch to support true 10G Ethernet . Supervisor 720 has brought extensive feature set such as MPLS, VPNs, and VSS over the last 10 years.  If has also spread throughout the world over the last 10 years as the graphic (created using Tableau) shows.

Supervisor 720 has served well and now the newest engine, the Supervisor 2T , launched in 2011, triples the performance of Supervisor 720, quadruples the scalability, adds support for 40G interfaces and is ready to support 100G. Supervisor 2T inherits all the great features of Supervisor 720 and delivers a broad set of additional features such as native VPLS, Flexible Netlfow, Trustsec, EVN, Medianet and Distributed Policing to mention a few. Supervisor 2T will also support OpenFlow, LISP, and next-generation VSS.

Investment protection is in my DNA. When a customer upgrades from Supervisor 720 to Supervisor 2T, the same E-series chassis, many of the line cards and service modules will work seamlessly.. Since both Supervisors are based on Cisco IOS, network administrators can leverage their expertise and existing operational processes for faster adoption.

Happy 10th Birthday, Supervisor 720! I look forward to celebrating the same for Supervisor 2T in 8 years.

  1. One of my favorite gears of all time, wish I could have setup one in my last DC upgrade, being on another group now, I'll be spectator newest DC replacement to 6506. Yet, good to know such investment will make it up for 10 years or more and allow transition to newer features as they are made available. Happy B'day!

  2. Hi, We resolved the IPv6 issue about 24 hours ago. Can you retry again, please? If you're still unable to connect, let me know. Thanks, Clint

    • Yes - looks to be all fixed and working well now over IPv6. Thanks Clint!

  3. Tech Problem: Seems that this site has an IPv6 IP address as well as an IPv4 address in DNS, but the web site isn't listening on the IPv6 IP. This is causing long timeouts for users like myself who are dual-stacked when attempting to access the site. As if that wasn't bad enough, I've just attempted to submit "feedback about", and after submitting all I get is a white page in my browser. I've no idea if that has actually submitted or not. Can you let me know where or who to report this to?

    • Hi Reuben, the best place to send tech issues with the page/website is the "feedback" link at the bottom of the web page. On that feedback form you can point the tech issues and the refering link or page location. Regards,

      • Thanks Roberto, but as I said in my posting, the feedback link below was also not working. Clicking on submit in the feedback form resulted in a blank white page, hence my posting here in the hope that someone might see it who can take a look.

    • Hi Ruben, I just sent your comment to the blog support team. Hope they can work on this. I'll let you know when I hear back. Thanks, Laurne
