Testing connectivity between RPR stations
You may use Echo Request/Echo Response messages to test the connectivity between two stations and
locate failure points if any. The connectivity between the current station and the destination station is
considered as normal if the connection between the two stations is normal on both the sending ringlet
and the receiving ringlet. The destination station should be able to receive the Echo Request messages
that the current station sends along the specific ringlet, and the current station should be able to receive
the Echo Response messages that the destination station sends along the specific ringlet. Otherwise, the
connectivity between the current station and the destination station is considered as having failed.
To test the connectivity to a specific RPR station:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter RPR logical interface
view.
interface rpr interface-number N/A
3. Test the connectivity between
the current station and a
specific station.
rpr echo mac mac-address [ -c
c-value | -r { ringlet0 | ringlet1 |
reverse } | -s { ringlet0 | ringlet1 }
| -t t-value ] *
By default, five Echo Request
packets are sent; it is the default
ringlet that sends Echo Response
packets and Echo Request packets;
the timeout time is 10 milliseconds.
NOTE:
If neither the sending ringlet nor the receiving ringlet is specified, the default ringlet in use will be used for
transmitting Echo Request packets and Echo Response.
