Network queue policies are applied on egress of access-uplink ports on the 7210 SAS-K 2F1C2T.
On the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C, network queue policies are applied on egress for access-uplink ports, network ports, and hybrid ports.
The network egress aggregate shaper rate can be configured for hybrid ports on the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C using the nw-egr-agg-shaper-rate command. Configuring the command limits the amount of traffic sent out of network IP interfaces configured on the hybrid port.
The network queue policies can be defined with up to a maximum of eight egress queues. The user has an option to define the policies with fewer than eight egress queues.
Queue characteristics configured on a per-FC basis are the following:
committed buffer size (CBS) in Kilobytes
maximum buffer size (MBS) in Kilobytes
peak information rate (PIR) as a percentage of egress port bandwidth
committed information rate (CIR) as a percentage of egress port bandwidth
queue priority and queue weight
Network queue policies are identified with a unique policy name that conforms to the standard 7210 SAS alphanumeric naming conventions. The system default network queue policy is named ‟default” and cannot be edited or deleted. The following table describes the default network queue policy definition in access-uplink mode.
