Requirements. Determine whether a peer is up or down by exchanging keepalive messages over the management link between the two Inter-Chassis Control Protocol (ICCP) peers. Description. 4R2-S3 JUNOS EX Software Suite [18. For every active session in a chassis cluster anchored on the SPU on the primary node, a backup session is created on the secondary node. JUNOS and config sync between RE is not a default behaviour, you have to manually ensure that JUNOS on both RE is compatible with HW/linecards in the box (JUNOS versions on both REs may be different if you don't use GRES) and to sync config, use Creating an event to take backup at a specific time: user@device# run show configuration event-options generate-event then { upload filename /config/juniper. The backup RE will then take mastership. Display information about the conditions that have been configured to trigger alarms.

Before upgrading, you must perform failovers so that all redundancy groups are active on only one device. It has advantages as well specifically while you are using the NAT becuase the NAT pool is doubled in active-backup compare to active-active. Having GRES enable, make the backup RE of being ready to keep on forwarding the traffic in case of switchover/failover: logically the forwarding plane ready on backup RE. The workaround in this case is to deactivate the accounting. conf, SNMP ifIndexes, /var Before you configure member IDs and Virtual Chassis ports, you must enable graceful Routing Engine switchover (GRES) and nonstop active routing (NSR) on both member routers in the Virtual Chassis. For details on how to configure 'show system alarms' automatically when an admin user logs in to the router or switch, refer to the You can use nonstop software upgrade (NSSU) to upgrade the software running on all member switches in most EX Series Virtual Chassis with minimal traffic disruption QFX10K8-RE1> show chassis alarms 2 alarms currently active Alarm time Class Description 2020-05-05 09:58:03 CDT Major Host 0 : Chassis Manager connection down 2020-05-05 09:56:33 CDT Minor Backup RE Active Another consequence is that in active-active mode when you configure PAT available ports are split in half between two nodes (even when deployed as active/backup). 3; ----- Remove this part of configuration then the backup node RE doesn't report the above logs any more and also routing engine CPU utilization back to normal. Primary RE and Backup RE out of sync (example from MX router) KB36633 : [Junos] Configuration not applied to backup RE when using different group names. Troubleshooting. Just login to backup re - through console, fxp, or through request routing-engine login other routing engine (although this last method doesn’t typically work when on different images in some cases).

I almost forgot. 4R2-S3-jet-1] Redundancy groups are for when you want the same connection to failover between the nodes in the cluster. To recover the primary partition, copy the running version into the primary partition of the device easily by executing the The in-service software upgrade (ISSU) feature allows a chassis cluster pair to be upgraded from supported Junos OS versions with a traffic impact similar to that of redundancy group failovers. A discard next-hop entry exists in the forwarding table, from the backup RE point of view, causing it to silently drop the packets towards the accounting servers. Manually getting the backup (I. Alarm time Class Description. e every 1st of June and every 1st of Dec) and be repeatable every year. Link protection helps to ensure that traffic going over a specific interface to a neighboring router or switch can continue to reach this router (switch) if that interface fails. Which command you use depends on the disk hardware of the platform. 4R2-S3] JUNOS Crypto Software Suite [18.
