Description This command defines a maximum total rate for all egress queues on a service SAP or multi-service
site. The agg-rate-limit command is mutually exclusive with the egress scheduler policy. When an
egress scheduler policy is defined, the agg-rate-limit command will fail. If the agg-rate-limit
command is specified, at attempt to bind a scheduler-policy to the SAP or multi-service site will fail.
A multi-service site must have a port scope defined that ensures all queues associated with the site are
on the same port or channel. If the scope is not set to a port, the agg-rate-limit command will fail.
Once an agg-rate-limit has been assigned to a multi-service site, the scope cannot be changed to card
level.
A port scheduler policy must be applied on the egress port or channel the SAP or multi-service site
are bound to in order for the defined agg-rate-limit to take effect. The egress port scheduler enforces
the aggregate queue rate as it distributes its bandwidth at the various port priority levels. The port
scheduler stops offering bandwidth to member queues once it has detected that the aggregate rate
limit has been reached.
If a port scheduler is not defined on the egress port, the queues are allowed to operate based on their
own bandwidth parameters.
The no form of the command removes the aggregate rate limit from the SAP or multi-service site.
SONET/SDH IPCP - The SAP is identified by the channel. No BCP is
deployed and all traffic is IP.
