The process of switching back network access to an interface detected as having been repaired.
The process of switching network access from a failed interface to a good physical interface. Network access includes IPv4 unicast, multicast, and broadcast traffic, as well as IPv6 unicast and multicast traffic.
The process of detecting when a NIC or the path from the NIC to some layer 3 device starts operating correctly after a failure.
A communication facility or medium over which nodes can communicate at the link layer. The link layer is the layer immediately below IPv4/IPv6. Examples include Ethernets (simple or bridged) or ATM networks. One or more IPv4 subnet numbers/prefixes are assigned to an IP link. A subnet number/prefix can not be assigned to more than one IP link. In ATM LANE, an IP link is a single emulated LAN. When using ARP, the scope of the ARP protocol is a single IP link.
Network adaptor that is either internal or a separate card that serves as an interface to a link.
A node's attachment to a link. This attachment is often implemented as a device driver plus a network adaptor. Some network adaptors can have multiple points of attachment, for example, qfe. The usage of Network Adaptor in this document refers to a "Single Point of Attachment."
The set of physical interfaces on a system that are connected to the same link. They are identified by assigning the same (non-null) character string name to all the physical interfaces in the group.
A name assigned to a physical interface that identifies the group. The name is local to a system. Multiple physical interfaces, sharing the same group name, form a physical interface group.
The process of detecting when a NIC or the path from the NIC to some layer 3 device starts operating correctly after a failure.
A physical interface that is not used to carry data traffic unless some other physical interface has failed.
