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

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.
