Hi all,

say in this example of a ifconfig -a.
Code:
ce1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 147.184.5.172 netmask ffffff00 broadcast 147.184.5.255
        ether 0:3:ba:ac:d1:9c

at times i do receive the output without the RUNNING word . what does this mean?
does indicate a network collision?

what is network collision - two or more tcp/udp connection trying to access the same network interface? say in this case ce1 ?
