Modulo firmware bugs. >>> So where I can find active flow-control setting for host interface? >> Can't check for ix just now, but for em(4) there is sysctl dev.em.0.fc. >> It should be similar for ix. > I have hw.ix.flow_control=3 (what does is it means ?) and dev.ix.0.fc=3 (and > what does is it means?) /* Flow Control Settings */ enum ixgbe_fc_mode { ixgbe_fc_none = 0, ixgbe_fc_rx_pause, ixgbe_fc_tx_pause, ixgbe_fc_full, ixgbe_fc_default }; So, ixgbe_fc_full = 3 (full rx/tx flow control enabled, see sys/dev/ixgbe/ixgbe_type.h). > Back to my original question: is it possible to monitor `netstat -n -p udp -f > inet -s` counters by SNMP? There is no standard MIB for these counters but you may always export it with net-mgmt/bsnmp-ucd port and custom OIDs if you use stock bsnmpd (bsnmp-ucd man page has an example). There is similar possibility for net-snmpd. _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
