Guidelines for Configuring Byte Adjustment of Cell and Frame Shaping Rates Using QoS Parameters

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 of 4 bytes. The maximum byte adjustment value that you can configure is 59. When you configure a byte adjustment value greater than 59 in a QoS parameter, the system automatically resets the value to 59.
