Recently, we received in LAB 2 new MPC cards: - The MPC4e Combo card: 2x100GE + 8x10GE ports (MPC4E 3D 2CGE+8XGE) - The MPC4e 32x10GE ports (MPC4E 3D 32XGE) These 2 new cards need at least the Junos 12.3 and can be used on both dense chassis: MX960 and...
Introduction Recently I carried out tests in labs to evaluate the FlowSpec implementation on MX960 router with TRIO MPC cards. I used a 12.3 Junos release. Those tests have covered: - IPv4 blackholing traffic feature - IPv4 rate-limiting traffic feature...

Last week, I worked on 2 small projects in 11.4 Junos. I should: - Find a way to automatically disable a physical link when LACP "flapped" too many times during a given time. - Find a way to automatically disable a physical link when too many CRC errors...

During a complex case on Juniper platform, I looked for a tip to capture transit traffic on a MX960 with Trio cards. Indeed, I suspected a Junos box to rewrite transit mpls traffic with an unexpected exp value. As I love carry out reverse engineering,...

A new short post today for network support technicians, engineers... One thing that you usualy check when you manage a case regarding service disruption is packet loss! The first step is to check if you have packet loss at physical layer due to framing...

This post describes how multicast Next-Hop resolution and caching is done on Junos MX routers with Trio based cards. To have more information regarding the multicast replication see my previous post here : Multicast Replication. 1/ Introduction: PIM join...

Troubleshooting Load-balancing is quite complex. Working on an operational team, I often need to know on which interface a given stream (IP or MPLS) will get out... Cisco IOX provides several cli commands to quickly compute and display the result of a...

The configuration of the load balancing parameters is done at the forwarding-option level. There are 2 parts, each one is related to a type of hardware: - hash-key : for Ichip based platforms on MX or T series FPC - enhanced-hash-key : for Trio based...

A simple op script, just for fun. Next blog post will be more serious :) FOR TERMINAL : 24 Rows / 80 Columns / font: Courrier New 10 The video can see here : The 'op' script is called lovejunos.slax. It has been tested with release 11.4. You can simply...

I try to explain load balancing on MX. This post does not cover all the cases, but tries to summarize the default behaviour depending on the type of card: ICHIP or TRIO based, to provide which fields can be add or remove to compute the hash and finally...

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...
