During the initial boot of the device the MTU of the tmm_bp kernel interface is out-of-sync with the value of sys db vlan.backplane.mtu as well as out-of-sync with the MTU displayed by the following command: tmsh show /net vlan all-properties -hidden. tmsh list net vlan tmm_bp all-properties -hidden. Additionally, running the following command: modify sys db vlan.backplane.mtu value <some value> (within the range accepted), and saving the configuration change does not last through a reboot.
When the values are seen at non-sync, after the modification of the backplane vlan mtu and saving the config, changing the mtu config value does not last through a reboot.
This issue occurs on the first boot intermittently.
Rebooting the device resolves the issue
