1. Question: Can I mirror the physical ports in the aggregation port separately?

Answer: The member ports in the aggregation port cannot be used as mirror destinations independently.
2. Question: How many one-to-many mirrors can I configure?
Answer: You need to pay attention to the number of configured interfaces of mac-loopback. If more than one configuration command is used, the network will be disconnected.
3. Question: Image data only receives one-way data from the mail?
Answer: (1) Whether the source port is both-way traffic.
(2) Whether the port data stream is full (including source port, MAC loopback interface, destination interface)
(3) The receiving and sending protocols of the mail are POP3 reception and SMTP transmission.
4. Problem: In the scheme of dynamic spoofing, ip dhcp snooping + DAI, if only DAI is configured, is ip dhcp snooping network normal?
Answer: The network will not work, and there is no legal arp entry on the switch.
5. Question: Is the ip address conflict problem prompted by the AP wireless user on the core?
Answer: If it is initiated by the wireless user terminal, then it is arp detection initiated by the wireless user which can be used for source protection on the wireless or filter the log on the switch.
6. Question: Show arp and view arp entry information. Is there an unresolved arp entry that will occupy the switch arp entry?
Answer: Yes, unresolved arp entries will also occupy the number of arp entries for the switch.
7. Question: How is the port connected to the AP connected to the switch?
Answer: When the customer deploys the wireless AP, if it is in local forwarding mode, the configuration on the switch is:
      Interface gi0/1
        Switchport mode trunk
        Switchport trunk native vlan xxx ------ stands for APvlan
     In the centralized forwarding mode, the configuration on the switch is:
      Interface gi0/1
        Switchport mode access
        Switchport access vlan xxx ------ represents APvlan
8. Question: What does a trunk port do when it receives data with the native vlan tag?
Answer: The tag will be taken off and then the French network will be available for each vlan access interface and the trunk interface.
9. Question: What is the difference between hybrid and trunk?
Answer: hybrid can specify which data to take or without tag through the hybrid interface, trunk can only configure voutlan without tags through.
10. Question: Interface division vlan error under web page
Answer: Please detect the following three aspects:
(1) Whether the interface is configured as a routing pattern
(2) Whether the interface is joined to the aggregation port
(3) Whether the interface is equipped with AnARP check

At the same time, both ends establish a TCP connection, and then the man-in-the-middle performs TCP connection between the two ends. Can a transparent proxy be understood as a simple and crude "hijacking" of a passing data packet, without splitting the complete TCP connection into two independent segments. So, in this sense, this kind of transparent proxy is similar to the working hierarchy of NAT devices?
