If i do 'ifconfig -a', i'm seeing the interface which i created. Under what circumstances does the interface is not shown in ifconfig output but in 'ifconfig -a' output. Also, i'm not seeing any packets forwarded to the created interface. i.e None of the Rx Packets and Tx Packets counters are getting incremented, Can any one please let me know your suggestions / any documentation related to this problem area. Thank you. ^ permalink raw reply [flat|nested] 4+ messages in thread

But I'm still not seeing any packets forwarded to that interface. Rx/Tx counters are not incrementing. How can i troubleshoot this problem?.
