Cumulus Linux Support File

Cumulus Linux generates support files called cl-support whenever issues are detected. 

This file is used to aid in troubleshooting customer issues. The Cumulus Networks global support staff often requests customers to provide this file when they open support tickets. 

The cl-support file is located in the /var/support directory and is named cl_support_xxx.txz.

There are three ways cl-support is generated:

  • If switchd or any other process generates a core file (located in /var/support/core), then the cl-support file is generated.

  • After the first failure of one of the following monitored services since the switch was rebooted or power cycled:

    • clagd
    • frr
    • openvswitch-vtep
    • portwd
    • ptmd
    • rdnbrd
    • switchd
    • vxrd
    • vxsnd
  • A cl-support file can be triggered by issuing the cl-support command.

    You should only run this command at the direction of a member of the Cumulus Networks support staff.

If you need to copy the cl-support file off of the switch to a remote host for collection, use scp:

cumulus@switch:~$ scp /var/support/ username@myserver:/path/
