Uplink Failure Detection (UFD) | 1095Sample Configuration: Uplink Failure DetectionFigure 54-7 shows a sample configuration of Uplink Failure Detection on a switch/router in which you:• Configure uplink-state group 3.• Add downstream links Gigabitethernet 0/1, 0/2, 0/5, 0/9, 0/11, and 0/12.• Configure two downstream links to be disabled if an upstream link fails.• Add upstream links Gigabitethernet 0/3 and 0/4.• Add a text description for the group.• Verify the configuration with various show commands.Figure 54-7.
