RoCE
Use the UI or CLI to monitor RDMA over Converged Ethernet (RoCE) for Spectrum switches and BlueField DPUs.
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 (dpu | nic)
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.
netq check roce
View RoCE Counters Networkwide in the UI
From the header or
menu, select Spectrum-X, then RoCE.
Select either RoCE switches or RoCE DPUs.
The RoCE switches tab displays transmit (TX) and receive (RX) counters as well as counter pools for all switches running RoCE in your network.
The RoCE DPUs tab displays physical port, priority port, RoCE extended, RoCE, and peripheral component interconnect (PCI) information for all DPUs running RoCE in your network.
View RoCE Counters for a Given Switch
You can view the following RoCE counters for a given switch:
- Receive and transmit counters
- General, CNP, and RoCE-specific counters
- Counter pools
- Port-specific counters
To view RoCE counters on a switch, search for the device’s hostname in the global search field or from the header select Add card > Device card. Select a switch that is running RoCE and open the large card on your workbench. Click the
RoCE tab to view RoCE counters and their associated ports:

Expand the card to the largest size, then select RoCE counters from the side menu. Use the controls above the table to view, filter, or export counter statistics by Rx, Tx, or Pool.
Disable RoCE Monitoring
To disable RoCE monitoring:
Edit
/etc/netq/commands/cl4-netq-commands.yml
and comment out the following lines:cumulus@netq-ts:~$ sudo nano /etc/netq/commands/cl4-netq-commands.yml #- period: "60" # key: "roce" # isactive: true # command: "/usr/lib/cumulus/mlxcmd --json roce counters" # parser: "local"
Delete the
/var/run/netq/netq_commands.yml
file:cumulus@netq-ts:~$ sudo rm /var/run/netq/netq_commands.yml
Restart the NetQ Agent:
cumulus@netq-ts:~$ netq config agent restart
