Verifying LLT configuration

After starting LLT, GAB and other component, run the following commands to verify the LLT configuration.

  1. Run the lltstat -l command to view the RDMA link configuration. View the link-type configured to rdma for the RDMA links.

    # lltstat -l

    LLT link information:
link 0  link0 on rdma hipri
mtu 8192, sap 0x2345, broadcast 192.168.27.255, addrlen 4
txpkts 171  txbytes 10492
rxpkts 105  rxbytes 5124
latehb 0  badcksum 0  errors 0
  2. Run the lltstat -nvv -r command to view the RDMA and non-RDMA channel connection state.

    LLT internally configures each RDMA link in two modes (RDMA and non-RDMA) to allow both RDMA and non-RDMA traffic to use the same link. The GAB membership-related traffic goes over the non-RDMA channel while node to node data-transfer goes over high-speed RDMA channel for better performance.

    # lltstat -rnvv active
