How is DHCP Option 43 configured on an AR
Option 43 is a vendor specific information option. If an AP and an AC are located on different network segments, the AP cannot discover the ACs through broadcast. To address this problem, configure Option 43 on the DHCP server to advertise AC's IP addresses to the AP. The AR functions as the DHCP server and the AC's IP address is 192.168.22.1. The configuration of Option 43 is as follows: - Based on the global address pool: [Huawei] dhcp enable [Huawei] ip pool huawei [Huawei-ip-pool-huawei] network 192.168.100.0 255.255.255.0 [Huawei-ip-pool-huawei] gateway-list 192.168.100.1 [Huawei-ip-pool-huawei] option 43 sub-option 3 hex 31302E31302E31302E31 //Run the option 43 sub-option 3 ascii 192.168.22.1 command. - Based on the interface address pool: [Huawei] dhcp enable [Huawei] interface gigabitethernet 1/0/0 //Enter the view of the interface connected to the AP. [Huawei-GigabitEthernet1/0/0] ip address 10.10.10.10 24 [Huawei-GigabitEthernet1/0/0] dhcp select interface [Huawei-GigabitEthernet1/0/0] dhcp server 43 sub-option 3 hex 31302E31302E31302E31 //Run the dhcp server option 43 sub-option 3 ascii 192.168.22.1 command. If an Option 43 contains multiple AC IP addresses, the IP addresses are separated by commas (,). The ASCII value of commas (,) is 2C. For example, if the ACs' IP addresses are 192.168.22.1 and 192.168.22.2, run the option 43 sub-option 3 hex 3139322E3136382E3130302E322C3139322E3136382E3130302E33 or option 43 sub-option 3 ascii 192.168.22.1,192.168.22.2 command.

Whether the USG6000 supports optional expansion cards
The USG6000 supports multiple types of interface cards to add the number of interfaces. It also supports bypass cards to enhance availability. Purchase them as required. The support of interface cards on models of various types are as follows: -The USG6310/6320/6510-SJJ does not support optional expansion cards. -The USG6306/6308/6330/6350/6360/6370/6380/6390/6507/6530/6620/6630 provides two WSIC slots for the optional 8GE-WSIC-8x1GE RJ45 interface card, 2xG8GE-WSIC-8x1GE RJ45 interface+2x10GE SFP+ interface card, 8GEF-WSIC-8×1GE SFP interface card, and 4GE-BYPASS-WSIC-2×electrical link bypass card. -The USG6650/6660 provides six WSIC slots for the optional 8GE-WSIC-8x1GE RJ45 interface card, 2xG8GE-WSIC-8x1GE RJ45 interface+2x10GE SFP+ interface card, 8GEF-WSIC-8x1GE SFP interface card, and 4GE-BYPASS-WSIC-2xelectrical link bypass card. -The USG6670/6680 provides five WSIC slots for the optional 8GE-WSIC-8x1GE RJ45 interface card, 2xG8GE-WSIC-8x1GE RJ45 interface+2x10GE SFP+ interface card, 8GEF-WSIC-8x1GE SFP interface card, and 4GE-BYPASS-WSIC-2xelectrical link bypass card.

What cautions should be taken when configuring DHCP Option 60 and Option 43 on a Layer 2/Layer 3 network?
DHCP Option 43 and Option 60 must be configured on a Layer 3 network, while they are optional on a Layer 2 network.

Configuring the DHCP Option 43 field on an AC
Perform the following operations to configure the DHCP Option 43 field on an AC that functions as a DHCP server: 1. Run the system-view command to enter the system view. 2. Run the dhcp enable command to enable the DHCP function. 3. Run the ip pool ip-pool-name command to enter the global address pool view. 4. Run the option 43 sub-option 2 ip-address ip-address &<1-8> command to set the DHCP Option 43 field to the IP addresses of the active and standby ACs.
