But clearly the problem was already happening before interface down, and first log entry is LACP timeout, which occurs 3s after the problem starts. Perhaps Juniper asserts for some reason RFI? Perhaps Cisco resets the physical interface once removed from LACP? > - why the same setup in DC2 do not report issues ? If this is is LACP related software issue, could be difference not identified. You need to gather more information, like how does ping look throughout this event, particularly before syslog entries. And if ping still works up-until syslog, you almost certainly have software issue with LACP inject at Cisco, or more likely LACP punt at Juniper. -- ++ytti _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
