Abstract
Abstract Management of a network device by a management client over a network using a network management protocol such as SNMP or DMI, with the managed device including multiple different protocol stacks for receiving network transmissions using multiple different protocols respectively corresponding to the multiple different protocol stacks. The management client obtains information from the managed device pertaining to the presence and identity of the multiple different protocol stacks. Thereafter, to manage the managed device, the management client sends multiple copies of the same network management packet to the same recipient over each of the different protocol stacks. If a single managed device includes plural different network interfaces, then multiple transmissions are also made to each different network interface. By virtue of this arrangement, since multiple copies of the same network management packet are sent to the same recipient, reliability of receipt of the management packet is increased.
