VSM CLI Tree Node Commands
cca-rate
Syntax cca-rate kilobits-per-second
no cca-rate
Context config cca>ccag ccag-id
Description This command defines a maximum forwarding rate for each CCA member within the CCAG. Support
of setting a maximum CCA forwarding rate is provided to prevent overrunning the ingress
forwarding plane when sub-line rate ingress features are enabled. The primary ingress feature
requiring this support is dual ingress access queuing. When dual ingress queuing is enabled on cross
connect SAPs, the CCA forwarding rate should be limited to a rate that prevents packet loss due to
ingress forwarding congestion. The specified limit is applied to the aggregate alpha and beta path
bandwidth.
The no form of the command removes CCA bandwidth rate limiting.
Parameters
kilobits-per-second — Defines the maximum CCA rate in kilobits per second. The actual Kilobits per
member-cca
Syntax [no] member-cca card-slot/mda-number
Context config>vsm>ccag ccag-id
Description This command adds and deletes provisioned CCAs from the CCAG. The only requirement to
defining a CCA member is that the defined MDA position be provisioned as type cca. A CCA does
not need to be populated in the defined MDA position prior to membership definition. A non-
populated CCA member is considered inactive from a CCAG perspective. A populated CCA member
will become active once it has been initialized by the system. A CCA member may be removed from
the CCAG or depopulated from MDA slot at any time. At least one member CCA must be active on
the CCAG for the CCAG to be placed in the operational state. Up to 8 member CCAs can be
configured per CCAG.
The no form of the command removes a CCA member from the CCAG. If the CCA does not exist or
is not currently a member of the CCAG, no error is returned. Once removed from the CCAG, all
forwarding through the specified CCA stops.
Parameters
card-slot/mda-number — Identifies the system MDA slot that is will be added as a member CCA for
