    2 figure 1 irf application scenario basic concepts this section describes the basic concepts that you might encounter when working with irf. Irf member roles irf uses two member roles: master and slave (called "subordinate" throughout the documentation). When switches form an irf fabric, they elect ...

    3 for two neighboring devices, their irf physical links must be bound to irf-port 1 on one device and to irf-port 2 on the other. Physical irf port physical irf ports connect irf member devices and must be bound to an irf port. They forward irf protocol packets between irf member devices and data pa...

    6 configuration synchronization mechanism irf uses a strict running-configuration synchronization mechanism so all chassis in an irf fabric can work as a single node, and after the master fails, other members can operate normally. In an irf fabric, all chassis get and run the running configuration o...

    7 detection the mad implementation of the switch detects active irf fabrics with the same layer 3 global configuration by extending the lacp or gratuitous arp protocol. These mad mechanisms identify each irf fabric with a domain id and an active id (the member id of the master). If multiple active i...

    19 configuring irf bridge mac persistence an irf fabric by default uses the bridge mac address of the master switch as its bridge mac address. This bridge mac address is used by layer 2 protocols, for example, lacp, to identify the irf fabric, and must be unique on a switched lan for proper communic...

    24 caution: excluding a vlan interface and its layer 2 ports from the shutdown action introduces ip collision risks because the vlan interface might be active on both the irf fabric in active state and the irf fabric in recovery state.
