## Symptoms

- * After upgrading a Quantum Maestro environment to R82, the Bond interface is not fully operational. Running `ethtool ` shows an incorrect or inconsistent link speed.

* The subordinate interface shows "churned" state. The `/proc/net/bonding/<bond_name>` file contains:

  `Actor Churn State: churned`

  `Partner Churn State: churned`
* When examining the `/proc/net/bonding/<bond_name>` file with the command `grep "port state:"`, the output shows inconsistent port state values (should be 61/63) across uplink ports:

  `port state: 63`

  `port state: 15`
* When examining the `/var/log/messages` file with the command `grep LACP`, the output shows that that the following script was not run after the boot phase:

  `/usr/scripts/align_the_local_LACP_bonds_to_chassis_monitor_bonds.py`

## Cause

During the upgrade process, the `LACP_SYNC pnote` is intentionally disabled.

This pnote is responsible for triggering the execution of this script:

`/usr/scripts/align_the_local_LACP_bonds_to_chassis_monitor_bonds.py`

Because the script is not executed after the upgrade completes, the LACP bond configuration is not synchronized across the Security Group Members (SGMs), and the bond state is inconsistent.
