In the case where the ODU is upgraded from an earlier release that does not support the
'Multiple Traffic Classes' feature, the classification rules will be initialized as defined in Table
9 modified to reflect the stored value of "VLAN High Priority Traffic Threshold". For example,
if the existing threshold was set to "VLAN User Priority 4 and Above" then the classification
rules would be initialized as shown in Table 10.
