This chapter provides information to configure network queue QoS policies using the CLI.
Network queue policies define the egress network queuing for the traffic egressing on the network ports and hybrid ports. Network queue policies are used at the Ethernet port and define the bandwidth distribution for the FC traffic egressing on the Ethernet port.
There is one default network queue policy. The default network queue policy defines eight queues and a mapping of FC-to-queue. The default policies can be copied but cannot be deleted or modified. The default policy is identified as network-queue default. Default network queue policies are applied to all network ports and hybrid ports. You must explicitly create and then associate other network queue QoS policies if the default values need to be modified.
On 7210 SAS-R6 and 7210 SAS-R12, the network queues are scheduled using a port scheduler. See Schedulers for information about the scheduler and its behavior.
A basic network queue QoS policy must conform to the following.
Configuring and applying QoS policies other than the default policy is optional. A default network queue policy is applied to all network ports.
To create an network queue policy, define the following:
FCs are mapped to the eight queues available on the port according to FC-to-Queue ID Map.
The following is a sample configuration output to create a network queue QoS policy.
Apply network queue policies to the following entities:
Use the following syntax to apply a network queue policy to an Ethernet port.
The default network queue policies are identified as policy-id default. The default policies cannot be modified or deleted.
The following are sample default policy parameters for 7210 SAS-R6 and 7210 SAS-R12.
The default network queue policies are identified as policy-id default and _tmnx_hybrid_default.The MPLS and IP traffic on hybrid ports arrives at the _tmnx_hybrid_default policy if there is no policy applied.
The following is a sample configuration output for default policy parameters for 7210 SAS-R6 and 7210 SAS-R12.
This section describes the service management tasks.
A network queue policy is associated by default with all network ports. You can replace the default policy with a user-configured policy, but you cannot entirely remove a QoS policy. When you remove a QoS policy, the policy association reverts to the default network-queue policy default.
A network-queue policy cannot be deleted until it is removed from all network ports where it is applied.
Use the following syntax to delete a user-created network queue policy.
The following example shows the command usage to delete a user-created network queue policy.
You can copy an existing network queue policy, rename it with a new policy ID name, or overwrite an existing network queue policy. The overwrite option must be specified or an error occurs if the destination policy ID exists.
Use the following syntax to copy and overwrite a QoS policy.
The following example shows the command usage to copy and overwrite a QoS policy.
The following is sample configuration output showing copied policies.
You can change existing policies, except the default policies, and entries in the CLI. The changes are applied immediately to all ports where the policy is applied. To prevent configuration errors, use the copy command to make a duplicate of the original policy to a work area, make the edits, and then overwrite the original policy.
