  • NX-OS Releases and Platforms – Majornetwork
    this post in 2012 the following new platform designators have been issued I for Nexus 9000 and Nexus 3164Q A for Nexus 3500 U is still used for Nexus 3000 3100 D for Nexus 7000 since NX OS 7 2 0 D1 1 This D designator for Nexus 7000 is brand new as of June 2015 Looks like Cisco wants Nexus 7000 to have an own letter as well I m still disappointed that Cisco didn t introduce the X letter for the fifth Nexus platform Updated June 19 2015 17 13 Tags nexus 1000v nexus 3000 nexus 3500 nexus 4000 nexus 5000 nexus 5500 nexus 7000 nexus 9000 nx os Previous Post Next Post 4 Comments Add a Comment Ian Erikson July 27 2012 at 15 32 Nice detective work Maybe we will see a top of rack switch Reply Markku Leiniö July 27 2012 at 21 20 Obviously it cannot be a plain FEX as they don t have user downloadable images But it is possible that the new platform is a hybrid platform that can be used both as a FEX and as a standalone switch That s my guess for now I don t bet for a Nexus 6000 yet because 7009 is still relatively new and 5596 is also not yet fully marketed and positioned yet Reply Markku Leiniö February 6 2013 at 22 51 Update for this Now there is Nexus 6000 announced but it uses the same N series designation as Nexus 5000 series So X is still available for something else Reply Markku Leiniö September 3 2014 at 22 44 The Nexus 9000 switches are using the I designation It means that they still haven t released the X software Reply Leave a Reply Cancel reply Search for Markku Leiniö Senior Network

  • IOS 12.2SX Software Releases – What to Use? – Majornetwork
    and it was announced in March this year SXJ1 was released on June 30 so it is still very fresh Extended maintenance is planned until March 21 2013 and critical maintenance until September 21 2013 When comparing these maintenance periods and noting the fact that SXJ is still a newcomer for me it looks actually quite clear SXI is the one that I should select for now I m not after any fancy new features like mLACP just need to keep the systems running reliably 12 2 50 SY is the first IOS release available for Sup2T I may need to get my hands on Sup2T s later this year so I hope Cisco will publish SY1 or similar first rebuild before that to polish some stains that usually exist in the first release Cisco s document about Catalyst 6500 12 2SX releases tell the facts about maintenance periods I quoted above http www cisco com en US prod collateral switches ps5718 ps708 prod bulletin0900aecd804f0694 html 12 2SX new features lists http www cisco com en US docs switches lan catalyst6500 ios 12 2SX release notes features html 12 2SXJ resolved and open caveats lists http www cisco com en US docs switches lan catalyst6500 ios 12 2SX release notes caveats SXJ html 12 2SXI rebuilds resolved and open caveats lists http www cisco com en US docs switches lan catalyst6500 ios 12 2SX release notes caveats SXI rebuilds html Updated August 11 2011 22 08 Tags cat6500 sup2t sup32 sup720 sxi sxj Previous Post Next Post Leave a Reply Cancel reply Search for Markku Leiniö Senior Network Architect Senior Technology Consultant and CCIE 26438 Routing Switching in Finland Majornetwork on Twitter Markku Leiniö on Google Your IPv4 IPv6 Status You are using IPv4 address 81 198 240 36 Recent

  • Life of a Change – Majornetwork
    or may otherwise be affected by the change I was finalizing my detailed Change Implementation Plan in this change it consisted of 40 lines of actions for 2 hour maintenance window each line consisting of various number of configuration commands for the devices Earlier this year I was leading a change that had 6 hour maintenance window six specialists doing the changes from four different companies plus the normal night shift servicedesk and IMOC Infrastructure Management Operations Centre people and consisting of 320 lines of actions in CIP with some 1500 lines of configuration commands In that sense this change was somewhat smaller deal I really like having a detailed plan because it enables me to follow a clear path during the change My reviewing colleagues also get a clear picture of the plan when almost nothing is assumed everything is written out T minus 2 days I confirmed with the participating SP specialist that everything was still fine and no new questions had arised I also checked that there were no open questions from the customer so there was nothing to prevent us from proceeding with the change T minus 12 hours I prepared myself for the following day s actions printed the CIP set wakeup alarm to 02 30 AM made some sandwiches in the fridge for a takeaway breakfast and set my phone to silent mode to ensure some sleep T minus 90 minutes The alarm clock went crazy Apparently I had had some sleep but it is always a bit lighter when you have an important change coming in the night I took a quick shower grabbed the sandwiches and a banana and drove off to the office complex The change involved implementing some brand new connections in the data center so I decided it s best to be near the data center while making the changes just to be sure if anything was needed onsite T minus 15 minutes I asked the Servicedesk to send the predefined starting announcement I also made some last minute checks in the monitoring systems to get a baseline of the network status and enabled some specific extra monitoring probes to get more direct information during the changes T minus 5 minutes I joined the conference call with the SP specialists This time they had two guys doing the change both of them I had worked with many times before It was nice to be working with people who you really trust and who are able to adapt to the current situation whatever it would be based on their experience I also knew that their attitude is customer focused It is very frustrating to try to fix something with a guy who thinks it s not a big deal maybe we can leave it here when something is broken These guys were something totally different T plus 0 minutes We started the changes and proceeded according to my CIP I won t go into details here it would be too
