Application Overview on page 283
When you specify the cell or frame byte-adjustment application, the following
considerations apply:
You can have only one QoS parameter definition with the cell byte-adjustment
application (qos-byte-adjustment) configured.
You can only have one QoS parameter definition with the frame byte-adjustment
application (qos-frame-byte-adjustment) configured.
You can specify only instance-interface types of lag, ethernet, svlan, and vlan.
You can specify only an subscriber-interface type of vlan.
The available range for parameters with the byte adjustment application is -32–63.
You cannot configure another range using the range command.
We recommend that you apply the byte adjustment parameter at the lowest interface
column so that upper interfaces automatically have the parameter.
On the ES2 10G LM, the shaping rate adjustment is performed more efficiently by the
TFA ASIC than ASICS on other modules. The TFA ASIC performs an internal adjustment
