A local link partner accesses in-band the management registers of a remote link partner. The local link partner generates and transmits a management message formatted according to a predefined communication protocol, under the direction of a network management system. The management message is generated according to a message template reserved by the predefined protocol for customization. The management message is transmitted in-band from the local link partner to the remote link partner. The management message can be transmitted when the local link partner is in an active mode or in an idle mode, as defined by the predefined communication protocol. The management message contains a first portion that identifies itself as a message reserved by the predefined protocol for customization. A second portion of the management message contains a management command. The remote link partner performs the management command, which can be a register read or write.
