aix etherchannel 切換方法和檢視方式

1、檢視etherchannel的配置，如下ent3為主，ent1為備
dbrac1:/@root>#lsattr -El ent4 
adapter_names   ent3           EtherChannel Adapters                       True
alt_addr        0x000000000000 Alternate EtherChannel Address              True
auto_recovery   yes            Enable automatic recovery after failover    True
backup_adapter  ent1           Adapter used when whole channel fails       True
hash_mode       default        Determines how outgoing adapter is chosen   True
mode            standard       EtherChannel mode of operation              True
netaddr         0              Address to ping                             True
noloss_failover yes            Enable lossless failover after ping failure True
num_retries     3              Times to retry ping before failing          True
retry_time      1              Wait time (in seconds) between pings        True
use_alt_addr    no             Enable Alternate EtherChannel Address       True
use_jumbo_frame no             Enable Gigabit Ethernet Jumbo Frames        True
2、檢視當前active的網路卡，active為主，即ent3：
dbrac1:/@root>#entstat -d ent4 |grep -i acti 
Active channel: primary channel  
3、切換方法：
Smitty etherchannel->Force A Failover In An EtherChannel / Link Aggregation
4、切換後，可執行#entstat -d ent4 |grep -i acti再次檢視
