Multi-Service Sites

Multi-Service Sites

A customer site can be designated a multi-service site where a single scheduler policy is applied to
all SAPs associated with the site while retaining per-service and per-forwarding class shaping and
policing. The SAPs associated with the multi-service site can be on a single port or on a single slot.
The SAPs in a multi-service site cannot span slots.
Multi-service sites are anchor points to create an ingress and egress virtual scheduler hierarchy.
When a site is created, it must be assigned to a chassis slot or port with the exception of the 7750
SR-1 in which the slot is set to 1. When scheduler policies are defined for ingress and egress, the
scheduler names contained in each policy are created according to the parameters defined in the
policy. Multi-service customer sites exist for the sole purpose of creating a virtual scheduler
hierarchy and making it available to queues on multiple Service Access Points (SAPs).
The scheduler policy association with the customer site normally prevents the scheduler policy
from being deleted until after the scheduler policy is removed from the customer site.
When the multi-service customer site is created, an ingress and egress scheduler policy association
does not exist. This does not prevent the site from being assigned to a chassis slot or prevent
service SAP assignment. After the site has been created, the ingress and egress scheduler policy
associations can be assigned or removed at any time.
Each customer site must have a unique name within the context of the customer. Modifications
made to an existing site immediately affect all SAPs associated with the site. Changing a scheduler
policy association can cause new schedulers to be created and existing queues on the SAPs to no
longer be orphaned. Existing schedulers on the site may cease to exist, causing queues relying on
that scheduler to be orphaned.
