Description: This object is used to indicate that the repeater detected an error-free training frame on this port with a non-null source MAC address which matches the value of vgRptrAddrLastTrainedAddress of another active port in the same repeater. This is reset to 'false' when an error-free training frame is received with a non-null source MAC address which does not match vgRptrAddrLastTrainedAddress of another port which is active in the same repeater.

For the cascade port, this object will be 'true' if the 'D' bit in the most recently received error-free training response frame was set, indicating the device at the other end of the link believes that this repeater's cascade port is using a duplicate address. This may be because the device at the other end of the link detected a duplicate address itself, or, if the other device is also a repeater, it could be because vgRptrMgrDetectedDupAddress was set to 'true' on the port that this repeater's cascade port is connected to.
