7.6. Misconfigurations

Sometimes poor network performance is due to misconfigured components. This can be difficult to identify because there no error statistic indicates a fault; the misconfiguration might be found only after meticulous scrutiny of all network settings.

Places to check: all interface settings (ifconfig -a), route tables (netstat -rn), interface flags (link_speed/link_mode, discussed in Section 7.7.6), name server configurations (/etc/nsswitch.conf), DNS resolvers (/etc/resolv.conf), /var/adm/messages, FMA faults (fmadm faulty, fmdump), firewall configurations, and configurable network components (switches, routers, gateways).
