Re: [j-nsp] Where do packets with incomplete ARP resolution go?
It typically is dropped... It has no where to send it so it drops it.

Basically what I'm asking is, is it hardcoded to being blackholed, or is there a way to redirect traffic to IPs that ARP is failing on to go to a MAC of last resort instead of being dropped? -- Kevin ___ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp ___ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
[j-nsp] JunOS on EX-4200 stack corruption
Has anyone seen an issues where, once a stack looses power (all at once, sadly), some members of the stack come up with corrupt JunOS on them? We have a stack of 6 EX4200's. Due to a power issue, all 6 lost power at the same time. When power was restored, the Master, the Backup and one linecard mode switch came up fine. The 3 other linecard mode switches didn't. On powerup they all reported shared libaries not being found and similar file not found type errors. Reinstalling JunOS from the boot prompt has fixed the problem. Has anyone else encountered corrupt JunOS problems on EX4200's, specifically in a stack configuration, before? Thanks!

Re: [j-nsp] JunOS on EX-4200 stack corruption
I've personally never seen this. Maybe the power issues affected the flash inside the switch? I doubt the same would happen if you pulled the power cords from all switches at once for example.

Yes, it's been a serious, ongoing problem for us. We have ~1200 switches across ~360 VCs. We're running JUNOS 10.0S1. There is a PR for the problem - it's PR/543776. There is no permanent fix as yet but there is a workaround available in 10.0R4, 10.1R4, 10.2R3, 10.3R2, 10.4R1 or later. It's called 'Automatic File System Mirroring and Automatic Recovery' and at this stage you'll need to talk to JTAC about it. cheers, Dale ___ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp

Oh look here, Juniper was one of the sponsors to write journaling support for FreeBSD's UFS: http://www.osnews.com/story/23205/FreeBSD_UFS_with_Softupdates_Journaling So maybe we'll see it in JunOS eventually. ___ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
