Abstract

A method, system and computer program product for managing at least two physical links. A TCP/IP stack configures a first interface with attributes. The TCP/IP stack activates the first interface. The TCP/IP stack detects a channel path identifier (CHPID). The TCP/IP stack creates a second interface. The TCP/IP stack associates the second interface with the first interface. The first interface and the second interface are logically linked to exchange traffic corresponding to a single internet protocol address. The TCP/IP stack configures the second interface with at least one attribute. The TCP/IP stack activates the second interface. The two physical links may rely on two different physical link types.

Claims9

Dependent claims

A computer implemented method for managing at least two physical links, the computer implemented method comprising:

configuring a first interface with attributes;
activating the first interface;
detecting a channel path identifier (CHPID);
creating a second interface;
associating the second interface with the first interface, wherein the first interface and the second interface are logically linked to exchange traffic corresponding to a single internet protocol address;
configuring the second interface with at least one attribute;
responsive to detecting the channel path identifier, copying configured attributes of the first interface to the second interface, wherein the first interface is a logical Ethernet interface, and the second interface is a logical HiperSockets interface;
and
activating the second interface.
