Everyday Ten Ask certcollection ccie written

1. Question: What standard protocol is used for port aggregation?

Answer: Standard Protocol for Port Aggregation is 802.3ad

2. Question: The switch has done port aggregation to connect to the computer. Can the computer be used normally?

Answer: The dynamic aggregation of the switch is connected to the computer. This interface cannot be used normally. The static aggregation does not need to be negotiated. The configuration can take effect immediately. The static aggregation configuration can be used normally after the terminal is connected.

3. Question: The aggregate interface modifies the MTU value. Does the MTU value of the physical interface change?

Answer: Modify the MTU value on the aggregation interface. The MTU value of the physical interface is still the default value.

4. Problem: Static link aggregation, one end is unplugged, and the other side is still up, causing the data not to switch to another line.

Answer: Because the middle is a photoelectric converter, the optical port is converted into multiple electrical ports, resulting in the other side not down.

5. Question: How to configure the mirror port in the case of port aggregation?

Answer: When configuring a mirrored port, if the physical interface is configured as an aggregation interface, it needs to be called in the aggregation port when mirroring.

6. Question: Is the serial number at both ends of the port aggregation the same?

Answer: The port aggregation group is locally valid, that is, the number of the two ends of the aggregation port can be different.

7. Question: Can an indirect HUB be implemented in port aggregation to achieve aggregation?

Answer: In the case of port aggregation, an indirect HUB can be aggregated. However, in order to ensure that the intermediate line is disconnected, it can be automatically detected. Dynamic link aggregation is required to detect the link.

8. Question: What is the default priority of LACP?

Answer: The LACP mode of port aggregation can be configured for priority with a default of 32768. This priority is that if the port aggregation is made on the device, the light port and the port are configured to do the aggregation together. Then, the priority determines which port pattern is made of port aggregation, the priority is configured to 0 to indicate that the interface state priority is the lowest, not to participate in the decision.

9. Question: Do Switch and Huawei switch port aggregation configuration lacp unsuccessfully?

Answer: It is recommended to use the actine mode at both ends. Otherwise, it will lead to the success of our negotiation but the data can not be forwarded properly.

10. Question: Can mirror ports be the destination interface or the source interface?

Answer: Many-to-many mirrors cannot be bidirectional and the same interface cannot be the source interface and the destination interface.
