RoCE

Use the UI or CLI to monitor RDMA over Converged Ethernet (RoCE) in your network.

RoCE Commands

The following commands display your network’s RoCE configuration, RoCE counters and counter pools, and RoCE-related events. See the command line reference for additional options, definitions, and examples.

netq show roce-config 
netq show roce-counters  
netq show roce-counters pool
netq show events message_type tca_roce
netq show events message_type roceconfig

The netq check roce command checks for consistent RoCE and QoS configurations across all nodes in your network fabric.
