SIMULATION 4 Guidelines This is a lab item in which tasks will be performed on virtual devices. Refer to the Tasks tab to view the tasks for this lab item Refer to the Topology tab to access the device console(s) and perform the tasks. Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window. All necessary pre-configurations have been applied. Do not remove any existing configurations from the devices, only those necessary to make the appropriate changes required to fulfill the listed tasks. Do not change the enable password or hostname for any device. Save your configurations to NVRAM before moving to the next item. Click Next at the bottom of the screen to submit this lab and move to the next question. When Next is clicked, the lab closes and cannot be reopened. Topology Tasks Routers R1 through R4 implement Ethernet Operations, Administration, and Maintenance operations. Perform the below configuration on R1 and R4. Configure E-OAM on interface E0/0. Configure link monitoring:

• Monitor error frames
• Set a high threshold equal to 400
• Set threshold action equal to error-disable

The initial configuration with IP addressing has been completed. Do not change the configurations except to fulfill the abovementioned tasks. Answer:

The commands enable Ethernet OAM on interface e0/0, start link-monitoring for errored frames, set the high-error threshold to 400 frames, and specify that the interface is put into err-disable state if that threshold is exceeded, exactly matching the requested behavior.
