It would be good to ping while this problem is happening, to see if ping stops at 3s before the syslog lines, or at the same time as syslog lines. If ping stops 3s before, it's link problem from cisco to juniper. If ping stops at syslog time (my guess), it's software problem. There is unfortunately log of bug surface here, both on inject and on punt path. You could be hitting PR1541056 on the Juniper end. You could test for this by removing distributed LACP handling with 'set routing-options ppm no-delegate-processing' You could also do packet capture for LACP on both ends, to try to see if LACP was sent by Cisco and received by capture, but not by system. -- ++ytti _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
