Verifying Ethernet Connectivity Between Cisco Proprietary RPR Ethernet

Access Ports

After successfully completing the provisioning procedures, you can test Ethernet c onnectivity between
the Ethernet access ports on the separate ML-Series cards using y our standard tests for Ethernet
connectivity.

CRC threshold configuration and detection

You can configure a span shutdown when the ML-Series card receives CRC errors at a rate that exceeds
the configured threshold and configured soak time. For this functionality to work in an SPR ring, make
the configurations on the POS members of SPR interface as specified in CRC Threshold Configuration,
page 4-11.
Monitoring and Verifying Cisco Proprietary RPR
After Cisco proprietary RPR is configured, you can monitor its status using the show interface spr 1
command (Example 17-4) or the show run interface spr 1 command (Exam ple 17-5).
Example 17-4 Example of show interface spr 1 Output
