3.1.12.2 Network QoS and Network Queue Policies on a Ring
Adapter Card or Module
Network QoS policies are applied to the ring ports and the add/drop port using the
qos-policy command found under the config>card>mda context. These ports are
not explicitly specified in the command.
Network queue QoS policies are applied to the ring ports and the v-port using the
queue-policy command found under the config>port context. Similarly, a network
queue policy is applied to the add/drop port using the add-drop-port- queue-policy
command, found under the config>card>mda context. The add/drop port is not
explicitly specified in this command.
The CLI commands for applying QoS policies are given in this guide. Their command
descriptions are given in the 7705 SAR Interface Configuration Guide.
3.1.12.3 Considerations for Using Ring Adapter Card or Module
QoS Policies
The following notes apply to configuring and applying QoS policies to a ring adapter
card or module, as well as other adapter cards.
1. The ring ports and the add/drop port cannot use a network queue policy that is
being used by the v-port or the network ingress port or any other port on other
cards, and vice-versa. This does not apply to the default network queue policy.
2. If a network-queue policy is assigned to a ring port or the add/drop port, all
queues that are configured in the network-queue policy are created regardless
of any FC mapping to the queues. All FC queue mapping in the network-queue
policy is meaningless and is ignored.
3. If the QoS policy has a dot1p value mapped to a queue that is not configured in
the network-queue policy, the traffic of this dot1p value is sent to queue 1.
4. If a dot1q-to-queue mapping is defined in a network QoS policy, and if the queue
is not configured on any ring port or the add/drop port, then all traffic received
from a port will be sent out from queue 1 on the other two ports. For example, if
traffic is received on port 1, it will be sent out on port 2 and/or the add/drop port.
5. Upon provisioning an MDA slot for a ring adapter card or module
(config>card>mda> mda-type) an additional eight network ingress queues are
allocated to account for the network queues needed for the add/drop port. When
the ring adapter card or module is deprovisioned, the eight queues are
deallocated.
