So based on this, as long as one of dhcp agents is Active&Up, DHCP should be working.

Per my understanding, one of them should be “STATUS=ACTIVE, ADMIN STATUS=UP” and the other should be “STATUS=DOWN, ADMIN STATUS=UP”. Otherwise, it should be wrong. Right?

Finally, I found there are two DHCP ports when I create a tenant network with DHCP enabled. That makes VM cannot start up due to fail to get its ip address. But why there two DHCP ports when I create the network is still under investigation. Do you have some hints for this? Thanks.
