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
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.
Values 0 — 100000000, max
Default max
aggregate — The aggregate keyword is optional and mutually exclusive to the cca keyword. When
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.
cca — The cca keyword is optional and mutually exclusive to the aggregate keyword. When cca is
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.

Syntax weight path-weight
no weight
Context config cca>ccag ccag-id>path {a | b}
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:
Alpha scheduling percentage = alpha-path-weight / (alpha-path-weight + beta-path-weight)
Beta scheduling percentage = blue-path-weight / (alpha-path-weight + beta-path-weight)
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.
Parameters path-weight — The path-weight parameter is required and is used by the system to determine the
scheduling percentage for both paths. Changing the path-weight for one path affects both paths
