#JUNIPER EX2200 FIRMWARE UPDATE HOW TO DOWNLOAD#
Now that Graceful Switchover is enable when you run the command you wont see the same warning about traffic being disrupted, this is because Graceful Switchover preserves interface and kernel information allowing the PFE to continue forwarding packets, even though one of the REs is unavailable.An Improper Neutralization of Special Elements vulnerability in the download manager of Juniper Networks Junos OS on SRX Seri. >request chassis routing-engine master switch This will be done by running request chassis routing-engine master switch from RE1 now. activate chassis redundancy graceful-switchoverĪfter commit synchronising those changes, you will need to set RE0 back to the Master Routing Engine.

Once the Routing-Engine has upgraded you need to re-enable graceful-switchover and non-routing, first, you will see why in moment.
#JUNIPER EX2200 FIRMWARE UPDATE HOW TO INSTALL#
Having failed over the RE now, all that needed is to repeat the same command as before request system software validate add /var/tmp/xxx reboot to install the new firmware on RE0 > request system software add /var/tmp/ reboot You can confirm by running show chassis routing-engine again on RE0ĬPU temperature 39 degrees C / 102 degrees FĬPU temperature 41 degrees C / 105 degrees F The other routing engine becomes the master. Toggle mastership between routing engines ? (no) yesĬomplete. Warning: Traffic will be interrupted while the PFE is re-initialized > request chassis routing-engine master switch This WILL cause a brief outage as the PFE is reset and the new firmware is loaded.
#JUNIPER EX2200 FIRMWARE UPDATE HOW TO MANUAL#
This is an manual process by running the command, from the current Master RE, request chassis routing-engine master switch. Having upgraded Backup RE, to reduce the downtime and service impact, you can failover the Master Routing Engine, so that the Backup becomes the new Master Routing Engine. Load averages: 1 minute 5 minute 15 minuteĬPU temperature 38 degrees C / 100 degrees F Last reboot reason Router rebooted after a normal shutdown.

> show chassis routing-engineĬPU temperature 37 degrees C / 98 degrees F > request system software validate add /var/tmp/ reboot Once on the Backup RE, you will need to run the command request system software validate add /var/tmp/xxx reboot. Having disabled both graceful-switchover and nonstop-routing, log onto the Backup RE, either by console or from the Master RE run the command request routing-engine login re1.
#JUNIPER EX2200 FIRMWARE UPDATE HOW TO UPGRADE#
Skipping this step can potentially result in the control plane and forwarding plane having two different JUNOS versions, which can cause a number of potential issues! deactivate chassis redundancy graceful-switchoverĭeactivate routing-options nonstop-routing Upgrade Process Currently, we would normally upload the package into the /var/tmp folder on the device in question ~]$ scp re0-mx480:/var/tmpĪfter just saying how you to link the two REs together, for an upgrade, you will need to disable graceful-switchover and nonstop-routing. Upload the new firmware version to wherever you normally keep it them. Set chassis redundancy graceful-switchover Set groups re1 interfaces fxp0 unit 0 family inet address x.x.x.x/x Set groups re1 system host-name re1-mx480 Set groups re0 interfaces fxp0 unit 0 family inet address x.x.x.x/x To link two Routing Engines together, you would need to apply similar configuration to what I used: set groups re0 system host-name re0-mx480 This post will go over what you will need to do upgrade an MX Router, in my setup I’ll be upgrading a Juniper MX480 Router and I’ll be doing the upgrade via the console port on each Routing Engine. This is being the case, when upgrading a MX you will need to upgrade each RE by individually.
#JUNIPER EX2200 FIRMWARE UPDATE HOW TO SERIES#
With most, if not, all MX Series above the MX80, they will come with two Routing Engines (RE), and both are independent of each other. As part of this increased access, one of our first tasks is it upgrade JunOS from 12.3R5.7 to 14.1R6.4. I said whenever I got the chance to upgrade a MX Series Router, I’ll get something noted down…… *raises hands* today is the day! As I’ve said in a few posts, there has been a lot of change and now team is now getting access to the Core Juniper MX Series Routers. In one of my previous post, I explained how you would go about upgrading a Juniper EX switch.
