please advice - what the meaning of FAILED word from ifconfig command

  1. Dose its mean that network from NIC isn't stable until this moment ?
  2. Not clearly if ifconfig read network status each some mili seconds?, I mean if network is stable so ifconfig should return the FAILED status to OK ?

yael

 ifconfig -a

   lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
       inet 127.0.0.1 netmask ff000000 
    e1000g0: flags=19000802<BROADCAST,MULTICAST,IPv4,NOFAILOVER,FAILED> mtu 0 index 2
         inet 0.0.0.0 netmask 0 
         groupname Mgmt_ipmp
         ether 0:21:28:58:ff:6 
    e1000g1: flags=11000803<UP,BROADCAST,MULTICAST,IPv4,FAILED> mtu 1500 index 3
          inet 0.0.0.0 netmask ff000000 broadcast 0.255.255.255
          groupname Mgmt_ipmp

man ifconfig

section called "INTERFACE FLAGS"

 FAILED

     The  interface  has  failed.  New  addresses  cannot  be
     created  on this interface. If this interface is part of
     an IP network multipathing group, a failover will  occur
     to another interface in the group, if possible

Sometimes IPMP notices a problem with an interface and marks it as FAILED (this means that the test has failed, not that there is a hardware problem). This is because either be "the link is down" or "the ping test failed" (assuming you have test addresses).
