According to your description, if you are concerned about link load sharing, you can try the following configuration case.


http://support.huawei.com/hedex/hdx.do?docid=EDOC1100007341&id=dc_cfg_eth-trunk_0045&text=Example%2525252Bfor%2525252BConfiguring%2525252BLink%2525252BAggregation%2525252Bin%2525252BManual%2525252B%252525253Cb%252525253ELoad%252525253C%252525252Fb%252525253E%2525252B%252525253Cb%252525253EBalancing%252525253C%252525252Fb%252525253E%2525252BMode&lang=en


If you are consulting for dual-link redundancy, you can implement Layer 2 redundancy through VRRP.

Virtual Router Redundancy Protocol (VRRP) is a fault-tolerant protocol. By configuring VRRP, you can switch services to the backup device in time when the gateway device fails, thus ensuring continuity and reliability of communication.

http://support.huawei.com/hedex/hdx.do?docid=EDOC1100007341&id=dc_cfg_vrrp_0001&text=%252525253Cb%252525253EVRRP%252525253C%252525252Fb%252525253E%2525252BConfiguration&lang=en

You can also implement redundancy through routing entries through a dual uplink design.


such as:


Ip route-static 0.0.0.0 0.0.0.0 link1

Ip route-static 0.0.0.0 0.0.0.0 link2 preference 100




When ip route-static link 1 fails, it is forwarded directly through link2.


Of course, you can also achieve this by dynamic routing.

@user_3257445 hello sir, I just searched the ar550 manual, the three pin interface is a DO interface, when one of the power supply failure a signal will be sent out of this interface to notice the connected device.

Hello! Yes, this is exactly what i need. Does it work "out of box"? My situation is: i tested few of those AR550, after i unplug one of power supply - nothing happenes.

@user_3257445 hello, I searched the ar550 manual, the manual said that the signal type which sent out of the DO interface when short circuit and open circuit is passive DO, it seems that no extra configurations are necessary for this function.
you said you testedd few of AR550 nothing happened when unplug one of the power supply, in fact, I'm not sure how the test is done, I googled that the passive DO signal needs the connected device is with power supply, maybe you can try this.
