Hi all, few days ago we upgraded a 6 members VC of ex4550 from 12.3R6 to 15R1.8. using nssu precedure. We have linjux boxes connected with LACP on different member. We checked all the requirement listed on: http://www.juniper.net/techpubs/en_US/junos14.2/topics/task/installation/ex-series-software-upgrading-nssu-fixed-virtual-chassis-cli.html
After we started the upgrade , all the LACP links went down (one by one depending on the upgraded member), even if linecards were up and running and connected to the VC. In the end, everything went back to normal when the master RE came up. Actually a member was still stuck with all the LACP ports in "detached" state: after a manual reboot, it went ok. Did anybody have a similar issue? Any suggestion for investigation? Thank you Simone _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
