Hi Jeff:
I read the manul you provided above and try some commands again. Here is my
commands and outputs:
-----
localhost:~# ip link del bond0
localhost:~# ip link add bond0 type bond mode active-backup
localhost:~# cat /proc/net/bonding/bond0

.......

Still get the wrong result.
I notice that this line "Ethernet Channel Bonding Driver: v6.1.27-2-lts"
is diffrent from the line in CentOS7:
-----
[root@guning ~]# cat /proc/net/bonding/bond0
Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)

Bonding Mode: fault-tolerance (active-backup)
Primary Slave: None
Currently Active Slave: None
MII Status: down
MII Polling Interval (ms): 0
Up Delay (ms): 0
Down Delay (ms): 0
----
(Yes, the first command I try in alpine work in CentOS!!!)

The ip-link(8) https://man7.org/linux/man-pages/man8/ip-link.8.html did not
tell me the BOND ARGS FORMAT.

Just checking: did you do "apk add iproute2" ?
It seems the "ip" version that comes by default in busybox may not
support all options and might be ignoring your arguments.
I was able to reproduce your error on busybox, and it went away after
I installed iproute2

Alternatively the wiki suggests installing the "bonding" packages and
configuring through the interfaces file which I guess does it
differently.

Cheers,

Guido

Thanks, I'll check it out!
