found that the following interface card is down.. so replacing it:-

Test on lan1: linkloop -i 1 0x00306E4A6AA6

error: expected primitive 0x30, got DL_ERROR_ACK
dl_error_primitive = 0x2d
dl_errno = 0x04
dl_unix_errno = 57
error - did not receive data part of message
Link connectivity to LAN station: 0x00306E4A6AA6

Thanks all.
