Abstract
A link extender node is used to extend links between end nodes and/or routing nodes in a system area network. A connection includes a first link, coupling an end or routing node to a local port of a first link extender, a second link coupling the remote ports of first and second link extenders, and a third link coupling the local port of the second link extender to an end or routing node. The link extender includes link exception detection logic and transmits a this link bad command on the link generating the exception and transmits an other link bad command on the link not generating the exception.
