Adding an ATM MPOA Client

A Multi-Protocol Over ATM (MPOA) Client (MPC) can be added to the system to allow ATM LANE packets that would normally be routed through various LANE IP Subnets or Logical IP Subnets (LISs) within an ATM network, to be sent and received over shortcut paths that do not contain routers.

MPOA can provide significant savings on end-to-end throughput performance for large data transfers, and can free up resources in routers that might otherwise be used up handling packets that could have bypassed routers altogether.

Only one MPOA Client is established per node. This MPC can support multiple ATM ports, containing LE Clients/Servers and MPOA Servers. The key requirement being, that for this MPC to create shortcut paths, each remote target node must also support MPOA Client, and must be directly accessible using the matrix of switches representing the ATM network.

A user with root authority can add this MPOA Client using the smit mpoa_panel fast path, or click Devices —> Communication —> ATM Adapter —> Services —> Multi-Protocol Over ATM (MPOA).

No configuration entries are required for the MPOA Client. Ease-of-use default values are provided for each of the attributes derived from ATM Forum recommendations.

Configuration help text is also available within MPOA Client SMIT to aid in making any modifications to attribute default values.
