What is docsIfExt2CmClearLearnedMacAddresses?
This write-only truth value, when set to true, tells the cable modem to purge all learned MAC addresses from its forwarding database except eSAFE and provisioned addresses; reading it always returns false. An admin uses it to flush stale client entries from a CM's bridge table, for example after reconfiguring customer-premises equipment behind the modem. Setting the value to true(1) clears the CM's learned-address table on that poll.
