Queue Sharing and Redirection
The system keeps an association counter for each queue group template and an association
counter for each queue ID within the template. The system also keeps an association counter
for each queue group created on a port.
When a network QoS policy is applied to an IP interface with the queue group parameter
specified:
If the operation above is successful, then:
When the queue group parameter is removed from an IP interface:
When a network QoS policy egress forwarding class redirection to a queue ID is removed or
added:
If the operation above is successful, then:

• If the queue group name does not exist as an egress queue group template, the QoS
policy application will fail.
• If a redirection queue ID within the policy does not exist within the egress queue
group template, the QoS policy application will fail.
• If the IP interface is bound to a port (or LAG) and the specified queue group name
does not exist on the port, the QoS policy application will fail.
• The system increments the association counter for the queue group template with the
same name as the queue group specified when the QoS policy is applied.
• The system increments the queue ID association counter within the queue group
template for each forwarding class redirected to the queue ID.
• If the IP interface is currently bound to a port (or LAG), the association counter for
the queue group on the port is incremented.
• The system decrements the association counter for the queue group template with the
same queue group name that was removed from the IP interface.
• The system decrements the queue ID association counter within the queue group
template for each forwarding class that had previously been redirected to the queue
ID.
• If the IP interface is currently bound to a port (or LAG), the association counter for
the removed queue group on the port is decremented.
• If a redirection is being added to a forwarding class and the queue ID does not exist
on the queue groups for IP interfaces where the QoS policy is applied, the redirection
will fail.
• The system finds all IP interfaces where the policy is applied.
• Finds all affected queue group templates based on the queue group associated with
the QoS policy on each interface.
