Validate Cabling

Warning: If this step is completed when NCNs are offline or shutdown, the information compared here will not match the actual connections. Therefore, this step should be re-run again once the whole system is up.

  1. To validate the cabling you can run command similar to below:

    canu validate shcd-cabling --ips 10.252.0.2,10.252.0.3 --tabs 40G_10G --corners J12,T36 --shcd ./SHCD.xlsx

    NOTE Modify the command to use the correct SHCD file and correct --tabs, --corners, and IP addresses.

    The output should look as follows:

    sw-spine-001
Rack: x3000    Elevation: u24

--------------------------------------------------------------
Port | SHCD                   | Cabling
--------------------------------------------------------------

1      ncn-w001:pcie-slot1:1    ncn-w001:pcie-slot1:2
2      ncn-w002:pcie-slot1:1    ncn-w002:pcie-slot1:1
3      ncn-w003:pcie-slot1:1    ncn-w003:pcie-slot1:1

sw-spine-002
Rack: x3000    Elevation: u24

--------------------------------------------------------------
Port | SHCD                   | Cabling
--------------------------------------------------------------

1     ncn-w001:pcie-slot1:2    ncn-w001:pcie-slot1:2
2     ncn-w002:pcie-slot1:2    ncn-w002:pcie-slot1:2
3     ncn-w003:pcie-slot1:2    ncn-w003:pcie-slot1:2

    In the returned output, look for differences between the SHCD and actual network configuration.

    In the above example, incorrect cabling was detected on the sw-spine-001 switch on port 1:

    1 ncn-w001:pcie-slot1:1 ncn-w001:pcie-slot1:2*

    The SHCD has the correct information on port 1 but the actual switch configuration is mismatched.

    To fix this issue, re-cable ncn-w001 so that it is correctly connected to sw-spine-001.

  2. Return to deploying the management nodes.
