1. If the configured ACL rule has an inclusion relationship, it should be noted that the rule number of the strict condition needs to be sorted first, and the rule number of the loose condition needs to be sorted later, to prevent the packet from hitting the loose condition rule and stop continuing to match, thus make it impossible to hit the strict conditions of the rules.

[RTA-aaa-domain huawei] authentication-scheme au1
[RTA-aaa domain-huawei] authentication-scheme au2

4. The second layer switch belongs to the data link layer device, which can identify the mac address information in the data frame, forward data according to the mac address, and record these mac addresses and corresponding port information in its own mac address table.

5. What is the number range of Layer 2 ACL?

6. Using the commands "vlan batch 10 20" and "valn batch 10 to 20", how many VLANs can be created respectively?

7. Which of the following statements about the Hybrid port are correct?
