Before enabling dual-link backup, complete the tunnel configuration and commit the
configuration on AC1 and AC2. If you enable dual-link backup before committing the
tunnel configuration, the configuration cannot be committed on the standby AC. As a
result, services cannot be switched to the standby AC after an active/standby switchover.
To prevent IP address conflicts, ensure that the IP address pools configured for APs on
AC1 and AC2 do not overlap each other.
Configure an IP address pool for APs on AC1.

[AC6605_AC1-ip-pool-ap-active] gateway-list 19.19.19.1

Configure an IP address pool for APs on AC2.

You can also manually assign IP addresses for APs in a batch. If this method is used, you
do not need to specify the IP address range in the address pools, but you still need to
configure an IP address pool and enable the DHCP server on each AC.
Manually perform the same service configurations on the ACs. Inconsistent service
configurations on the ACs will cause service switching failures.
To prevent network storms caused by loops on the Layer 2 network, configure port
isolation on AC interfaces connected to the aggregation switch or enable MSTP on the
aggregation switch.
Configure port isolation on AC1.
[AC6605_LSW1]port-isolate mode l2
[AC6605_LSW1] interface GigabitEthernet 0/0/1
[AC6605_LSW1-GigabitEthernet0/0/1] port-isolate enable
[AC6605_LSW1] interface GigabitEthernet 0/0/2
[AC6605_LSW1-GigabitEthernet0/0/2] port-isolate enable
Configure port isolation on AC2.
[AC6605_LSW2]port-isolate mode l2
[AC6605_LSW2] interface GigabitEthernet 0/0/1
[AC6605_LSW2-GigabitEthernet0/0/1] port-isolate enable
[AC6605_LSW2] interface GigabitEthernet 0/0/2
[AC6605_LSW2-GigabitEthernet0/0/2] port-isolate enable
It is recommended that MSTP be enabled on the aggregation switch to prevent loops. For
details on how to enable MSTP on the aggregation switch, see the configuration guide of
the switch.
In Layer 2 networking, the ACs can use only IP addresses of VLANIF interfaces as their
source IP addresses to communicate with APs. In Layer 3 networking, the ACs can also
use loopback addresses as source IP addresses.
