Easy RoCE Config

Section titled “Easy RoCE Config”

Table 2 Easy RoCE Config

CommandPurpose
qos roce {lossless|lossy} [cable-length length] [incast-level level] [traffic-model model]Enable “Easy RoCE”, and create a configuration template.
qos service-policy {roce_lossless|roce_lossy|RoCE_profile_name}Apply “Easy RoCE” configuration to all interfaces.
qos roce RoCE_profile_nameEnter the RoCE template configuration view.
bind interface {all|ethernet interface_name|range interface_name_list}Apply the RoCE configuration template to the specified interfaces.

qos roce {lossless|lossy} [cable-length

Section titled “qos roce {lossless|lossy} [cable-length”

[Command] qos roce {lossless|lossy} [cable-length length] [incast-level level] [traffic-model model]

[Purpose] Enable “Easy RoCE”, and create a configuration template.

[Parameters]

ParameterDescription
lengthSpecify the cable length, choose from 5m/40m/100m/300m.
levelSpecify the traffic incast model, choose from low/medium/high
modelSpecify the traffic model, choose from throughput/latency/balance.

[View] Global Configuration View

[Notes] To enhance the user-friendliness of AsterNOS in RoCE scenarios, we support “Easy RoCE” configuration and management. There are two modes in RoCE scenario: “Lossless Ethernet” and “Lossy Ethernet”. In lossless mode, the system will automatically generate lossless configuration templates, with default DSCP mapping, enabling PFC and ECN for queue 3 and 4, and setting strict priority scheduling for queue 6 and 7. At the same time, it is supported for you to enter the corresponding configuration view to modify the parameters. Run command no qos roce {lossless|lossy} to remove “Easy RoCE” configuration. CX732Q-N-V2 devices currently do not support.

[Use Cases]

sonic(config)# qos roce lossless
or
sonic(config)# qos roce lossless cable-length 5m incast-level low traffic-model latency
Notice: Creating new RoCE profile roce_lossless_5m_low_latency

qos service-policy {roce_lossless|roce_lossy|

Section titled “qos service-policy {roce_lossless|roce_lossy|”

[Command] qos service-policy {roce_lossless|roce_lossy|RoCE_profile_name}

[Purpose] Apply “Easy RoCE” configuration to all interfaces.

[Parameters]

ParameterDescription
RoCE_profile_nameSpecify the name of RoCE profile.

[View] Global Configuration View

[Notes] Run command no qos service-policy {roce_lossless|roce_lossy|RoCE_profile_name} to unbind all interfaces. CX732Q-N-V2 devices currently do not support.

[Use Cases]

sonic(config)# qos service-policy roce_lossless
Notice: interface 0/0,0/4 has already bind other policy, pleace manually bind roce_lossless to the interfaces
or
sonic(config)# qos service-policy roce_lossless_5m_low_latency
