InDatagrams | Indicates the total number of UDP datagrams delivered to UDP users
NoPorts | Indicates the total number of received UDP datagrams for which there was no application at the destination port.
InErrors | Indicates the number of received UDP datagrams that could not be delivered for reasons other than the lack of an application at the destination port.
OutDatagrams | Indicates the total number of UDP datagrams sent from this entity.
HCInDatagrams | Indicates the number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT.
HCOutDatagrams | Indicates the number of UDP datagrams sent from this entity, for devices that can transmit more than 1 million UDP datagrams for each second. Discontinuities in the value of this counter can occur at reinitialization of the management system, and at other times as indicated by discontinuities in the value of sysUpTime.
