access
Syntax access
Context config>vsm>ccag ccag-id
Description This command changes the current CLI context to the CCAG access nodal context. The access nodal
context contains the qos adaptation command used to control the SAP QoS distribution across the
active member CCAs within the CCAG.
The CCAG access nodal context always exists and cannot be removed.
adapt-qos
Syntax adapt-qos {link | distribute}
no adapt-qos
Context config>vsm>ccag ccag-id>access
Description This command controls how the CCAG SAP queue and virtual scheduler buffering and rate
parameters are adapted over multiple active CCAs. Two adaptation modes are supported; link and
distributed.
The no form of the command returns the CCAG access QoS adaptation rule to the default setting of
distribute.
Parameters link — The link keyword is mutually exclusive with the distributed keyword. When link is
specified, the CCAG will create the SAP queues and virtual schedulers on each CCA with the
actual parameters defined in the QoS and scheduler policies. This mode is useful when
conversation hashing places all or most traffic over a single CCA.
Values link or distribute
Default distribute
distribute — The distribute keyword is mutually exclusive with the link keyword. When
distribute is specified, the CCAG SAP queues and schedulers on each CCA will receive a
portion of the defined parameters in the QoS and scheduler policies. The portion is decided on an
IOM basis with the ratio determined by the number of active CCA members on the IOM relative
to the total number of active members within the CCAG. The following equation may be used to
determine the actual ratio:
IOM-parameter-value = (IOM-active-CCA / total-active-CCA) * policy-parameter-value
Values link or distribute
Default distribute
cca-rate
Syntax cca-rate kilobits-per-second
