This is used to add and delete rows from this table dynamically. The RowStatus textual convention has been defined in the SNMPv2-TC MIB (RFC 2579). According to this RFC, the meaning of the different RowStatus states for this table is as follows: - active: the HMTS may perform unicast, multicast and broadcast communication with the device, using the communication parameters specified in the corresponding row. It does not matter whether or not there exists a physical device with the specified MAC address, or whether it is responding or not. - notInService: the HMTS may not perform any communication with the device with the specified MAC address. Traps for this device will not be forwarded to any EMS. - notReady: the RowStatus will be notReady if one or more of the following conditions is met: * the MAC address in the corresponding row is either all-zeroes, or a multicast MAC address. * the IP address is not 0.0.0.0, the HMTS is IP based and there is another active row with the same IP address. * the community string is not equal to hmtsDefaultCommString, the HMTS is community based and there is another active row with the same community string. * No forward port has been configured, or a non-existing forward port has been specified. During auto discovery if the row did not have a Reverse port ID assigned (that is the row status is notReady) and the reverse port id has been discovered then the HMTS may automatically activate the row. However, if the row status is notInService than the HMTS shall not automatically activate the row. Entries that are not active in this table or have the default IP address or community string shall not appear in the tables hmtsIPDevTable and hmtsCommDevTable.
