[sol10, sol9] 네트워크 카드 (ce) 링크 모드 등 정보 확인 및 변경방법

1. ifconfig -a 로 모든 NIC정보 확인
[LDSCEZDN01P:root:/ 3371] ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
ce0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 111.111.222.333 netmask ffffffc0 broadcast 111.111.222.255
        ether 01:12:43:33:aa:6

3. auto 모드인지 확인하려면 아래와 같이 실행. 결과가 1이면 auto모드임.
# ndd -get /dev/ce adv_autoneg_cap
1

4. 100 full-duplex일 경우 아래와 같이 실행해서 결과가 1
# ndd -get /dev/ce adv_100fdx_cap
1
