AC6605 Access Controller
Dual-Link Backup White Paper

The ACs must deliver the same VAP to an AP. Manually add offline APs to AC1 and
AC2. It is recommended that the same AP ID be configured for an AP on AC1 and AC2.
Run the following commands:
AC6605_AC1] wlan
[AC6605_AC1-wlan-view] ap id 0 ap-type WA601 mac 0025-9876-2633 sn A0928182
[AC6605_AC2] wlan
[AC6605_AC2-wlan-view] ap id 0 ap-type WA601 mac 0025-9876-2633 sn A0928182
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
[AC6605_AC1-ip-pool-ap-active] gateway-list 19.19.19.1
[AC6605_AC1-ip-pool-ap-active] network 19.19.19.0 mask 255.255.255.0
[AC6605_AC1-ip-pool-ap-active] excluded-ip-address 19.19.19.2
[AC6605_AC1-ip-pool-ap-active] excluded-ip-address 19.19.19.151 19.19.19.254
[AC6605_AC1-ip-pool-ap-active] option 43 sub-option 3 ascii HuaweiAC-19.19.19.1,
19.19.19.2 //This configuration is optical in Layer 2 networking but is
recommended.
Configure an IP address pool for APs on AC2.
[AC6605_AC2] ip pool ap-standby
[AC6605_AC2-ip-pool-ap-standby] gateway-list 19.19.19.2
[AC6605_AC2-ip-pool-ap-standby] network 19.19.19.0 mask 255.255.255.0
[AC6605_AC2-ip-pool-ap-standby] excluded-ip-address 19.19.19.1
[AC6605_AC2-ip-pool-ap-standby] excluded-ip-address 19.19.19.3 19.19.19.150
[AC6605_AC2-ip-pool-ap-standby] option 43 sub-option 3 ascii HuaweiAC-19.19.19.1,
19.19.19.2 ///This configuration is optical in Layer 2 networking but is
recommended.
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.
