What Should I Do When Finding a MAC Address Flapping Alarm?

If the alarm is reported only once, ignore it. If the alarm is reported multiple times, find the first and second interfaces where the MAC address is learned. Shut down the second interface to locate the loop. Then adjust the networking to remove the loop.

 Can a Traffic Policy Be Configured in a Super-VLAN or Sub-VLAN to Make the Traffic Policy Take Effect?

The packets received and sent by the switch configured with VLAN aggregation carry sub-VLAN tags but not super-VLAN tags, so a traffic policy must be configured in all sub-VLANs of a super-VLAN. A traffic policy in the super-VLAN does not take effect.

 Why Are IP and DHCP Packets Isolated When Only Layer 2 Isolation Is Configured on the Switch?

The Layer 2 isolation function isolates packets that are forwarded based on the MAC address table, while the Layer 3 isolation function isolates packets that are forwarded based on the routing table. When IP and DHCP packets are transparently transmitted in the switch based on the MAC address table but no the routing table, Layer 2 isolation takes effect on IP and DHCP packets.
