value | -t value | -p value ] *
View
RPR logical interface view
Parameters
mac-address: MAC address of the destination station to be detected.
station-name: Name of the destination station to be detected. You can select either
station name or MAC address.
-s: Specifies the sub-ring to send test frames. You cannot configure default sub-ring for
transmitting packets.
-r: Specifies the sub-ring to receive test frames.
-c: Specifies the number of packets to be sent.
-t: Specifies the timeout time to wait for acknowledgement.
-p: Specifies whether OAM operations need to be protected in the steer mode.
Description
Use the rpr echo command to test station connectivity. If two stations are connected
correctly at the physical layer, but the connection fails at the service layer, you can use
the Echo Req/Echo Rsp message to test the failure. The source station sends an Echo
Req message. When receiving it, the destination station gives the sender an Echo Rsp
message. If the source station receives the Echo Rsp message within the specified
time, it shows the connection is correct. Otherwise, it shows the failure between the two
stations.
Examples
# Detect whether the connection to station A whose Mac address is 000F-E211-1116 in
the ring is correct.
