ABSTRACT:
Systems and methods are provided for exchanging Small Network Management Protocol (SNMP) messages in a multi-network system between devices across different networks and a network management station. Network identification information is provided into SNMP messages transmitted across a common network backbone. A respective SNMP firewall provided at the networks extract the network identification information to determine if the SNMP message is addressed to a device in the respective network. The SNMP firewall removes the network identification information and forwards the SNMP message to the destination device if the SNMP message is associated with a device in the respective network. Providing network identification information in the SNMP messages allows devices in different networks to have similar IP addresses, while still allowing current SNMP tool sets to facilitate network managements when networks are coupled to one another to form a larger more complex network.
