Bulk port configuration 15

Boot Speed — Set the port speed. Possible values are Auto Negotiate (to auto-negotiate the speed) and 1, 2, 4, 8, and 16 Gbps and unknown speeds.

Boot Option — From the list, select one of the following:

•Auto Discovered From Fabric — Enables Boot over SAN using boot LUN information stored in the fabric. This is the default setting.

•First Visible LUN — Enables Boot over SAN from the first discovered LUN in the SAN.

Bootup Delay — Enter a bootup delay value. Valid values are 0, 1, 2, 5, and 10 minutes and the default value is 0 minutes. The Bootup Delay feature allows you to configure the delay to device discovery, offsetting the disk spinup delay time when servers and storage devices are powered on simultaneously.

-Port Topology — Specify the topology type. The supported topology mode is point-to-point (p2p) or loop. You can set the toplogy to loop only if QoS and Target Rate Limiting are disabled.

-QoS — Enable the Quality of Service (QoS) feature to assign traffic priority (high, medium, or low) for a given source and destination traffic flow. By default, all flows are marked as medium.

NOTE

NOTE: QoS and Target Rate Limiting cannot be enabled at the same time.

QoS Percentage — The QoS priority flow value extends QoS support by allowing the user to configure custom bandwidth values for High, Medium, and Low QoS priorities. The QoS % value represents the bandwidth in percentage for each of the priorities (high, medium, and low) and the three values must equal 100 percent.

The default priority flow settings of the switch are 60 (high), 30 (medium), and 10 (low). If QoS is disabled and enabled again without providing the high, medium, and low bandwidth values, the default values are applied.

-vNIC Configuration — Enables you to configure a single physical CNA Ethernet port into multiple virtual Network Interface Cards (vNICs).

•Enter the maximum allowable output bandwidth in increments of 100 Mbps in the vNIC Max Bandwidth (Mbps) box. The maximum bandwidth is 10 Gbps and this is the default.

•Enter the minimum allowable output bandwidth in the Min Bandwidth (Mbps) box. The minimum bandwidth is 0 Mbps. A zero value of minimum bandwidth (the default) implies that no bandwidth is guaranteed for that vNIC.

•BB Credit Recovery — Enables you to enable or disable buffer-to-buffer (BB) credits, which are a flow control mechanism that represent the availability of resources at the receiving port. Supported state change notification (BB_SCN) values are from 1 through 15 and the default is 1.
