This chapter provides information to configure network queue QoS policies using the CLI.
On the 7210 SAS-K 2F1C2T, network queue policies define the egress network queuing for the traffic egressing on the access-uplink ports. Network queue policies are used at the Ethernet port and define the bandwidth distribution for the FC traffic egressing on the Ethernet port. The user can define the number of queues and the mapping of FC-to-queue per network-queue policy. Each of these queues are shared by unicast and multicast traffic.
On the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C, network queue policies define the egress network queuing for the traffic egressing on the access-uplink port, and for the traffic egressing from the network IP interface configured on the network port or hybrid port. Network queue policies define the bandwidth distribution for the FC traffic egressing on the Ethernet port. The user can define the number of queues and the mapping of FC-to-queue per network-queue policy. Each of these queues are shared by unicast and multicast traffic.
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 access uplink ports, network ports, and hybrid ports.
To create a network queue policy, define the following:
The FC-to-queue ID mapping can be defined by the user in the policy. The user has an option to use fewer queues.
Use the following syntax to create a network queue QoS policy.
This section provides information about applying network queue policies.
Use the following syntax to apply a network queue policy to an Ethernet port in access-uplink port mode.
Use the following syntax to apply a network queue policy to an Ethernet network port in network port mode or hybrid port mode.
The default network queue policies are identified as policy-id default. The default policies cannot be modified or deleted.
The following is a sample of default policy parameters for the 7210 SAS-K 2F1C2T.
The following is a sample of default policy parameters for the 7210 SAS-K 2F6C4T.
The following are sample default policy parameters for the 7210 SAS-K 3SFP+ 8C.
This section describes the service management tasks.
A network queue policy is associated by default with all access uplink ports. You can replace the default policy with a customer-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.
The following shows the command usage 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 a 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.
