My previous post has presented an hidden command for analysing in real time fabric statistics. I've developed a small op script, for the MX platform, that provides in one command the PFE/Fabric IN/OUT statistics for all the Fabric Planes (0 to 5) for...
Small tips for analyse the fabric stats. I mean packets stats (IN/OUT/Drops) between each PFE and the Fabric. Usually fabric stats can be observe by using the following cli command. Remember, that there are only 2 streams at fabric level: High and Low...

Sometimes you may need to have some additional interface statistics, for example the amount of packets per range of sizes. You can use netflow to collect some stats like these. But if you don't have netflow on all your router interfaces or for troubleshooting...

The aim of this post is to provide the detailed procedure for upgrading the Switch Control Boards (SCB) of an MX960 chassis in order to overcome some limitations of the old SCB that are : - Unable to use the full load of the 16x10GE card and to keep fabric...
Sometimes it may be very useful to monitor only protocol and link events especialy during maintenance windows. Hereafter, I monitor : - Link UP/DOWN - ISIS adj UP/DOWN - OSPF neighbor UP/DOWN - LDP neighbor/session UP/DOWN - MPLS LSP UP/DOWN - RSVP neighbor...
I've planned to write posts during the next weeks regarding these subjects: - Enhanced-SCB's detailed migration procedure on MX960: get the full power of your MX and your 3D cards. - Understanding Hashing / Load-balancing on MX: for ichip/TRIO based cards....
Hello, I've opened this blog to share my passion for networking and especially networking on Junos platform. I provide technical information only based on my experience, my tests in Lab and the public documentations. I'm a french guy and my english is...
