QoS for the oversubscribed 16 x 10GE modules
18
Setting the server and storage modes
The default mode is qos rcv-scheduler fq-sp which is strict priority mode. This is used for the Server
mode. This command sets the queues (TC) associated to the uplink ports. Each network port is
assigned one low and high priority queue. In the either mode, queues 1-4 are low priority and 5-8
are high priority. For example, network port 1 uses queues (TC) 1 and 5. In the strict priority mode
the scheduling between high and low priority is strict.
For both Server or Storage mode, the network control traffic will use Drop Precedence 0. (DP0) The
incoming network control traffic will be assigned DP0 and all other traffic will be assigned DP1.
This will allow the module to prefer network control during congestion conditions. Network control
traffic will always be assigned to the high priority queue that is associated to the incoming network
port.
Switching between server and storage modes
For Server mode, the default is qos rcv-scheduler fq-sp which is strict priority mode. This command
sets the queues (TC) associated to the uplink ports. In either mode, queues 1-4 are low priority and
5-8 are high priority. Each network port is assigned one low and high priority queue. For example,
network port 1 uses queues (TC) 1 and 5. In the strict priority mode the scheduling between high
and low priority is strict. To enable the fair queuing strict priority mode, enter a command such as
the following.
BigIron RX(config-if-e10000-4/2)#qos rcv-scheduler fq-sp
Qos profiles
The 16 x 10GE module uses QOS profiles to define the QOS treatment applied to packets. Each 16
x 10GE module has 16 different QOS profiles that are used on the traffic coming from the network
ports. The profiles include traffic class and drop precedence. Each port will have the following QOS
profiles.
1. TCx (low priority), DP1
2. TCx (low priority), DP0
3. TCx (high priority), DP1
4. TCx (high priority), DP0
Table 94
represents the QOS profiles required for the ingress direction.
