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.
