Troubleshooting Bonded Interfaces

Troubleshooting Workflow

1. Connect to the command line.

2. Log in to the Expert mode.

3. Check the status of the bond:

   cat /proc/net/bonding/<bond id>

4. If there is a problem, check if the physical link is down, as follows:

   1. Execute the following command:

      • In Gaia Clish:

        show cluster bond name <bond_name>

      • In the Expert mode:

        cphaprob show_bond <bond_name>

   2. Look for a subordinate interface that reports the status of the link as no.

   3. Check the cable connections and other hardware.

   4. Check the port configuration on the switch.

5. Check if a VSX Cluster Member is down, by running:

   • In Gaia Clish:

     show cluster state

   • In the Expert mode:

     cphaprob state

   If any of the VSX Cluster Members has a State other than Active, see the R82 ClusterXL Administration Guide - Chapter Monitoring and Troubleshooting Clusters.

On a VSX Cluster Member, reboot is needed after the following actions on a bond interface:

1. Changing a bond mode.

2. Adding a subordinate interface into a bond

   Note - Removing a subordinate interface does not require reboot.

For further information regarding bond status and failovers, view logs in the Logs & Events view. Any interface bond status change is logged and can be viewed in Logs & Events.
