values for these ports will show what the customer configured, but the actual hardware results will be in steps of
2%.
This limitation only applies to 5Gbps ports. Ports running at 2.5Gbps have the same 1% granularity as all
previously-offered port speeds.
Error messages
When the show interface PORT-LIST smartrate command is run on a non-Smart Rate port, the
command will fail with an error message similar to the following: Port A1: This command is only
applicable to Smart Rate ports.
When the show interface PORT-LIST smartrate 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 A1: This
command did not complete successfully. Please try again.

Limitations on 5Gbps ports
For 5Gbps ports, when the customer has Rate-Limiting or Guaranteed Minimum Bandwidths configured, the
granularity of percentage-based rates for the 5Gbps speed is in steps of 2%. For example a 1% rate-limit for a
5Gbps port will function as a 2% limit, a 5% limit will function as a 6% limit. The Guaranteed Minimum Bandwith
profiles will show the same behavior. On an 8-queue system, the actual default servicing profile will be 2% 4%
30% 10% 10% 10% 16% 20%. The CLI and SNMP values for these ports will show what the customer
configured, but the actual hardware results will be in steps of 2%.
NOTE:
This limitation only applies to the 5Gbps ports. Ports running at 2.5Gbps have a 1% granularity in
port speeds.
