Description

This article describes the procedure to perform diagnostics on ISL E Ports.
Use this procedure to configure a basic D_Port diagnostics session between two switches

These tests can be done if trunking is not being formed or to verify the length of the ISL.

Note: The distance is based on the roundtrip time of a frame and can differ from the physical distance due to WDM equipment or patch panels.

A physical length difference of +/- 20 meters for ISLs within the same fabric is supported in the MetroCluster environment.

The test performs:

  • Electrical loopback
  • Optical loopback
  • Measurement of the link distance
  • Link traffic test
