hi, just thought I'd post an update.... it seems that we hit 3(!) bugs in the upgrade process. 2 of them are now documented and one is in the process of being documented.
fundamentally, SXI has a new default line added to the config...which meant that our second supervisor couldnt come up....we fixed this by removing the offending line in the working sup720 - but by this time, it was too late - the system thought there was a failure and then attempted to use ISSU to recover the previous image. ah..oh. we upgraded from SXF15a so there wasnt ISSU activity....(this also affects upgrades from SXH). anyway, this is where the oif and ltl came from - what had now happened is that any multicast groups that were being joined got their IGMP join locked in the MLS switching fabric...stuck.... never to work. only groups that hadnt been borked during the dual sup720s being present would work. the instant fix was to switch off hardware switching of multicast to flush these stuck registers etc and then very quickly(! ;-) ) turn it back on. we await resolution of the dual 720 bug that we hit..but a reload is needed as part of that..so has to wait a little longer. thanks to Cisco engineers involved in looking at this case. it was certainly 'interesting' alan _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
