Queue Sharing and Redirection
Queue groups are objects created on access or network Ethernet port or ingress forwarding
plane of an IOM/IMM/XMA that allow SAP or IP interface forwarding classes to be
redirected from the normal type of queue mapping to a shared queue. Queue groups may
contain queues, policers, or a combination or the two depending on the type of queue
group.The following types of queue groups are supported:
• 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.
