combination or the two depending on the type of queue group.The following types of queue

Access ingress supports a single queue group instance per ingress port, or multiple queue
groups created at the ingress forwarding plane level of the IOM/IMM/XMA. Access
ingress port queue groups may only contain queues, whereas access ingress forwarding
plane queue groups may only contain policers.
Access egress supports the creation of multiple queue groups per egress port. These queue
groups may only contain queues.
Network ingress supports the creation of multiple queue groups at the ingress forwarding
plane level of the IOM/IMM/XMA. These queue groups may only contain policers.
Network egress supports the creation of multiple queue groups per egress port. These
queue groups may contain queues, only, or queues and policers.
Access SAP port queue group supported on IOM-1 of types the iom-10g, iom-20g, and
iom- 20g-b. Network queue groups are not supported.
Access SAP port and network port queue group are supported on IOM-2s. Up to 20K
SAPs per MDA can be configured with any supported Ethernet MDA.
Access SAP port and ingress forwarding plane and network port and ingress forwarding
plane queue groups are supported on IOM-3s.
