This object, when read, returns a value of other(1) unless it is in the middle of rewriting the management memory. At such times, it will return rewriting(3). The state will revert to other(1) when the action is completed. Setting this variable to rewrite(2) will cause the SCP to attempt to rewrite the management Memory on the clock-card. Attempts to set this variable to all other values result in an error. Rewriting the management memory gets rid of duplicate entries, and thus may increase the available space. This action should be allowed to complete before intentionally removing power from the SCP or clock card. If the value is set to clearAndLock(4), management memory is completely erased. From this point on, SNMP operations that write management memory will fail, except for sets to the mgmtMemoryData object. In fact, the clearAndLock action must be set before management memory can be re-written using the mgmtMemoryData object. The GIGAswitch must be rebooted after the clearAndLock action (and after it has been re-written, if so desired) in order to allow future SNMP operations to be logged to management memory.
