Yes, default logging on the Nexus is different on different series switches and at least on the 7k/9k is also a giant trap (a Nexus 9k by default *disables mac address learning for 120s in a vlan* if it doesn't like the amount of mac moves, but DOES NOT LOG that it happened). For full mac logging on 7k/9k series: logging level l2fm 5 Or less verbose, but still logging when mac address learning is disabled (%L2FM-3-L2FM_MAC_FLAP_DISABLE_LEARN), setting l2fm log level to 3 should suffice (theoretically): logging level l2fm 3 As per: https://www.cisco.com/c/en/us/support/docs/switches/nexus-7000-series-switches/200424-Nexus-L2FM-4-L2FM-MAC-MOVE-syslog-expla.html IOS: mac address table notification mac-move N3K: mac address table notification mac-move ; logging level fwm 6 ; logging monitor 6 N4K: mac address table notification mac-move ; logging level fwm 6 ; logging monitor 6 N5K/N6K: mac address table notification mac-move ; logging level fwm 6; logging monitor 6 N7K/N9K: logging level l2fm 5 Also see: https://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/nx-os-software/213906-nexus-9000-mac-move-troubleshooting-and.html Who could have known that datacenter operators want to know when the switch stops learning mac address on an entire vlan for 120 seconds... cheers, lukas _______________________________________________ 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/
