Network requirements
On the network shown in
, perform the following operations:
•
Enable Ethernet OAM on Switch A and Switch B to auto-detect link errors between the two devices
•
Monitor the performance of the link between Switch A and Switch B by collecting statistics about the
error frames received by Switch A
