Troubleshooting the Cluster

You can use the CCL Ping tool to make sure the cluster control link is operating correctly. You can also use the following tools that are available for devices and clusters:

  • Troubleshooting files—If a node fails to join the cluster, a troubleshooting file is automatically generated. You can also generate and download troubleshooting files from the Devices > Device Management > Cluster > General area. See Generate Troubleshooting Files.

    You can also generate files from the Device Management page by clicking More (more icon) and choosing Troubleshoot Files.

  • CLI output—From the Devices > Device Management > Cluster > General area, you can view a set of pre-defined CLI outputs that can help you troubleshoot the cluster. The following commands are automatically run for the cluster:

    • show running-config cluster

    • show cluster info

    • show cluster info health

    • show cluster info transport cp

    • show version

    • show asp drop

    • show counters

    • show arp

    • show int ip brief

    • show blocks

    • show cpu detailed

    • show interface ccl_interface

    • ping ccl_ip size ccl_mtu repeat 2

    • show nve

    • show route

    • show tech-support

    You can also enter any show command in the Command field. See View CLI Output for more information.
