Smart Rate is a new technology designed to enable higher port link speeds on legacy cabling where an Ethernet RJ45 port type can link at 1Gbps, 2.5Gbps, 5Gbps, or 10Gbps.
When situations occur where a network link establishes at a lower than expected speed (or not at all) due to marginal or bad cabling, the Smart Rate port technology allows administrators to triage cabling issues and determine root causes of lower than expected performance.
Smart Rate Technology is available on the following products:
| HP Switch 5400R v3 zl2 modules (J9991A, J9995A) |
| HP Switch 5400R chassis switch bundles (JL002A) |

When the show interface command is run on a non-Smart Rate port, the command will fail with an error message similar to the following: PORT-LIST smartratePort A1: This command is only applicable to Smart Rate ports.
When the show interface command is run on a Smart Rate port, but is unable to retrieve all results the command will fail with an error message similar to the following: PORT-LIST smartratePort A1: This command did not complete successfully. Please try again.
