Used to create, modify, or delete a row in this pseudowire table; once a row is active, only this object and pwL2tpv3StorageType can still be modified. Admins use it to provision a new pseudowire session or remove an existing one, and should be aware that once active, other configuration columns become effectively locked until the row is taken out of active state. To reconfigure a PW's MTU after it's already active, an admin would need to work through pwL2tpv3RowStatus's state transitions rather than directly overwriting pwL2tpv3Mtu on an active row.
