CoS - Transmit Queue Mappings (Transmit Queue Port Group)

This tab lets you view and configure the transmit queue mappings for a port group. Transmit queue mappings map a logical rate limit index used by classes of service to an actual physical rate limit you have created in ExtremeCloud IQ Site Engine.

Each port group has its own set of index mappings. ExtremeCloud IQ Site Engine automatically assigns these index numbers when you configure a class of services' rate limits and transmit queue shapers.

The Transmit Queue Mappings tab allows you to do two things:

Map the index to a different rate for different port groups (edge ports versus inter-switch links). See Creating Class of Service Port Groups
Map the index to a different rate limit for each port type (8-rate limit, 32-rate limit, 64-rate limit, and 100-rate limit) in a port group. See Advanced Rate Limiting by Port Type.

To access this tab:

Open the Control tab.
Open the Policy tab.
Open the Class of Service > CoS Components left-panel tab.
Select either the Transmit Queue Port Groups left-panel tab.
Select a existing port group in the left panel to open it in the Transmit Queue Port Group tab.

NOTE:

Create a new port group by right-clicking the Transmit Queue Port Groups left-panel tab, selecting Create Port Group, entering a Name for the port group, and selecting OK.

Select the CoS - Transmit Queue Mappings tab in the right panel.

TXQ Index: The logical transmit queue index. This index number is specified in a class of service and dictates the queue and shaping behavior for incoming packets.

Transmit Queue: Displays the physical transmit queue used to map to each transmit queue index. To change this value, select the Edit Index Mapping button to open the Edit Transmit Queue Mapping window and select a value in the Transmit Queue drop-down list.

Rate Shaper: The transmit queue's associated rate shaper. To change this value, select the Select Rate Shaper button to open the Select Transmit Queue Rate Shaper window and select a value in the Rate Limit field.

TXQ Port Type: The Port Type is based on the number of transmit queues the port supports: 4 transmit queues or 16 transmit queues.

TXQ Index Used By CoS: The Class of Service using this TXQ index.
