Dell S4148U-ON OS10 Enterprise Edition User Guide Release 10.4.0E R2 - Page 575

Command Mode Usage Information Example TRUST-MAP If the trust map does not define dot1p values to any traffic class, those flows are mapped to the default traffic class (0). If some of the dot1p values are already mapped to an existing traffic class, you will receive an error. You should have a 1:1 dot1p to traffic class mapping for PFC-enabled CoS values. You should also have a common dot1p trust map for all interfaces using DCB. The no version of this command returns the value to the default. OS10(conf-tmap-dot1p-qos)# qos-group 5 dot1p 5 Supported Releases 10.3.0E or later qos-group dscp Configures a dscp trust map to the traffic class. Syntax qos-group tc-list [dscp values] Parameters • qos-group tc-list - Enter the traffic single value class ID (0 to 7). • dscp values - (Optional) Enter either single, comma-delimited, or a hyphenated range of dscp values (0 to 63). Default Command Mode Usage Information Example 0 TRUST-MAP If the trust map does not define dscp values to any traffic class, those flows are mapped to the default traffic class (0).

OS10(conf-tmap-dscp-qos)# qos-group 5 dscp 42 Supported Releases 10.3.0E or later queue-limit Configures static or dynamic shared buffer thresholds. Syntax Parameters queue-limit {queue-len value | thresh-mode [dynamic threshold-alpha-value | static threshold-value]} • queue-len value - Enter the guaranteed size for this queue (0 to 8911). Defaults: • 45 Kb (10G)/111 Kb (40G) if queue is priority flow control enabled • 2 Kb (10G)/8 Kb (40G) if queue is lossy/link-level flow control • If this is a priority flow-control queue, this configuration is invalid • Only supported for POLICY-MAP-CLASS-MAP (pmap-c-queue) mode • thresh-mode - (Optional) Buffer threshold mode. • dynamic thresh-alpha-value - (Optional) Enter the value indexes to calculate the shared threshold to the enable dynamic shared buffer threshold (0 to 10). Defaults: • 0 = 1/128 • 1 = 1/64 • 2 = 1/32 • 3 = 1/16 Quality of service 575
