So I've changed redundancy mode to to RPR (Route Processor Redundancy, was SSO) then stand-by RSP was ejected physically. I expected that errors would stop or would not change at all but neither happened. Instead, error rate decreased significantly but not ceased (12:25 was the moment): http://www.grosbein.net/cisco/eobc0_0-day.png Also something strange happened with these stats that I consider as "fabric utilisation": CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsInUtil.1.0 = INTEGER: 25 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsInUtil.1.1 = INTEGER: 37 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsInUtil.2.0 = INTEGER: 6 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsInUtil.2.1 = INTEGER: 5 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsInUtil.3.0 = INTEGER: 8 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsInUtil.3.1 = INTEGER: 1 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsInUtil.4.0 = INTEGER: 4 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsInUtil.4.1 = INTEGER: 4 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsInUtil.5.0 = INTEGER: 0 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsInUtil.6.0 = INTEGER: 0 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsOutUtil.1.0 = INTEGER: 7 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsOutUtil.1.1 = INTEGER: 12 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsOutUtil.2.0 = INTEGER: 13 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsOutUtil.2.1 = INTEGER: 18 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsOutUtil.3.0 = INTEGER: 13 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsOutUtil.3.1 = INTEGER: 13 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsOutUtil.4.0 = INTEGER: 7 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsOutUtil.4.1 = INTEGER: 11 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsOutUtil.5.0 = INTEGER: 0 CISCO-CAT6K-CROSSBAR-MIB::cc6kxbarStatisticsOutUtil.6.0 = INTEGER: 0 Here are corresponding graphs. Modules 5 and 6 (RSPs) almost always show zeroes, graphs for modules 1 and 4 do not show any unusual but graph for modules 2 and 3 do: http://www.grosbein.net/cisco/f10-day.png http://www.grosbein.net/cisco/f11-day.png http://www.grosbein.net/cisco/f20-day.png http://www.grosbein.net/cisco/f21-day.png http://www.grosbein.net/cisco/f30-day.png http://www.grosbein.net/cisco/f31-day.png http://www.grosbein.net/cisco/f40-day.png http://www.grosbein.net/cisco/f41-day.png I get RSP and configuration back and graphs restore to previous shapes. _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
