The default interval for aging switch (such as S3700-28TP-SI-AC)MAC addresses is five minutes. Check whether the aging of MAC addresses makes response packet traffic be forwarded to incorrect ports, interrupting services.
In addition, check whether the traffic is forwarded through different boards, and whether MAC entries must be synchronized between boards to perform Layer 2 forwarding. Check whether services are impacted when MAC entries are not synchronized.
Run the display mac-address aging-time command to query the MAC address aging time.
