Type: TruthValue
Access: read-write
Description: Flush all dynamic entries if the value is true.
What is tnMacDynamicClear?
This read-write TruthValue, when set to true, flushes all dynamically learned MAC address entries from the switch's MAC table. An admin uses this as an on-demand action to force the switch to relearn its dynamic MAC table from scratch, useful after a topology change or when troubleshooting stale forwarding entries. For example, after moving several devices between ports, an admin would set this object to true to immediately clear out the now-incorrect dynamic entries rather than waiting for them to age out naturally.
Examples
