Creating a domain name match rule
The LB device stores mappings between domain names and IP addresses in the DNS cache. If the destination IP address of an incoming packet matches an IP address in the DNS cache, the LB device queries the domain name for the IP address. If the queried domain name matches the domain name configured in a match rule, the LB device takes the LB action on the packet.

2. Enter LB class view. | loadbalance class class-name | N/A |
3. Create a domain name match rule. | match [ match-id ] destination domain-name domain-name | By default, an LB class does not have any match rules. |
