Configuring MDA Access and Network Pool Parameters

MDA-level pools are used by ingress network queues. Network policies can be applied (optional)
to create and edit QoS pool resources on egress network ports, channels, and ingress MDAs.
Network-queue and slope policies are configured in the

Configuring MDA Policies for Named Pools Mode

Network ingress queues can use either MDA ingress named pools or ingress default pools but not
port named pools. In the case with an IOM with multiple MDAs sharing the same buffer space
(iom3-xp, iom-10g) , network ingress queues will use only the MDA 1 named pools. Even if
named pools are configured for MDA 2, they will not be used by network ingress queues. Network
ingress queues configured to use MDA2 named pools will be considered pool orphaned. To check
for orphan queues, use the command "show mda <mda> qos ingress orphaned-queues".
SAP shared queues use by default the SAP shared pool; a sytem reserved buffer pool. Shared
queues can be configured to use MDA named pools. Shared queues cannot be configured to use
port pools since they are not port specific queues. In case a shared queue is configured to use a port
named pool, the queue will be considered orphan and will get buffers from access ingress default
pool.
For complete QoS configuration details reference the Named Pools section of the QoS Guide.
Interface Named Pools configuration details are located in the Interface CLI portion of this guide.
