1-4Status Analysis Solutionof the fabric are not the same, or thepassword configured does not match.passwords for the local deviceand the fabric as the same.How XRN WorksWhen a fabric is established, the devices determine their respective roles in the fabric by comparingtheir CPU MAC addresses. The device with the lowest CPU MAC address is elected as the master andthe other devices are slaves.After the election, the fabric can operate normally. The following three functions of XRN can providesimple configuration mode, enhanced network performance and perfect redundancy backupmechanism for users.DDMDDM is a new device management mode provided by XRN. In normal cases, a fabric can be consideredas a single device. You can manage the entire fabric by logging onto any device in the fabric withdifferent logging modes. The devices in the fabric synchronize their configurations by exchangingpackets, thus ensuring stability of the fabric.FTM program uses Unit ID, or device ID to distinguish between the devices in a fabric when youmanage them. On initialization of the XRN function, each device considers its Unit ID as 1 and after afabric connection is established, the FTM program automatically re-numbers the devices or you canmanually configure the Unit ID of them.The master in a fabric collects the newest configurations of the user and the slaves periodicallysynchronize the configurations from the master. In this way, the entire fabric can operate with the sameconfigurations.DLAAs a new link aggregation mode, DLA can improve fault tolerance and redundancy backup of usernetworks.Link aggregation enables you to configure ports on the same device as an aggregation port group,avoiding network interruptions resulted from single port failure. Based on link aggregation, DLAprovides a more reliable solution, with which you can select ports on different devices to form anaggregation port group. In this way, single port failure can be avoided and network reliability can begreatly improved, because the fabric can communicate with the destination network through ports onother devices in case a single device fails.XRN Fabric ConfigurationXRN Fabric Configuration Task ListComplete the following tasks to configure XRN fabric:Task RemarksSpecifying the Fabric Port of a Switch RequiredSpecifying the VLAN Used to Form an XRN Optional
