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.
