Access to the available bandwidth is dependent on the various parameters associated with each object
egress queue.
The specified rate may be defined as an aggregate path rate for all CCAs in the CCAG or it may be
defined as a per CCA path rate.
The no form of the command removes path rate limiting from all CCAs in the CCAG membership list
for the path.
Default
None (rate limiting the alpha path must be explicitly defined)
Parameters
kilobits-per-second — Defines the path rate in kilobits per second. The aggregate and cca keywords

Description
This command defines a scheduling weight to the aggregate output of the alpha and beta paths. The
specified weight is used to calculate a scheduling percentage for each path. The percentage for each
path is based on:
Based on the above calculation, the sum of the alpha and beta scheduling percentage always equals
100 percent. When one path is not using all of its available scheduling bandwidth, the other path may
use the remainder.
The no form of the command returns the path-weight for the path to the default value of 50.

specify how the defined rate is applied on a per CCA basis. The actual rate at each CCA is
rounded up to the nearest 50Mbps.

aggregate is specified, the defined rate is divided among the CCAs in the CCAG member list
based on the number of active CCAs. If three CCAs are active, the rate is divided by three and
the result is applied to each active CCA. If a fourth CCA becomes active on the CCAG, the
defined rate is then divided by four with the result applied to each CCA member on the CCAG.
The actual rate at each CCA is implemented in 50Mbps increments. The system will adapt the
specified rate to the best rate available per CCA.
Default When the kilobits-per-second parameter is specified, the default keyword is
aggregate.
specified, the defined rate is applied to all CCAs in the CCAG member list. The actual rate at
each CCA is implemented in 50Mbps increments. The system will adapt the specified rate to the
best rate available per CCA.
Alpha scheduling percentage = alpha-path-weight / (alpha-path-weight + beta-path-weight)
Beta scheduling percentage = blue-path-weight / (alpha-path-weight + beta-path-weight)
