1、查看etherchannel的配置,如下ent3为主,ent1为备
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、查看当前active的网卡,active为主,即ent3:
dbrac1:/@root>#entstat -d ent4 |grep -i acti
Active channel: primary channel
3、切换方法:
Smitty etherchannel->Force A Failover In An EtherChannel / Link Aggregation
4、切换后,可执行#entstat -d ent4 |grep -i acti再次查看
