I don't have a lab ready for testing right now but AFAIR fxp0 is still active for a disabled node even on branch (all the more so for high-end, since it's directly on RE there). Moreover "request routing-engine login node X" should also be available. By now I don't really remember the details but there is absolutely no doubt, it's possible to access a disable node throughout the network, not only on console. About half a year ago we've run into an bug in 10.0R2 causing losses of heartbeats on control link and consequent regular failovers and node disabling. No doubt it was possible to reboot the disabled node without having access to console. _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
