3Com SuperStack II 9300 Command Reference Manual page 367

The VLAN aware mode reflects the difference in tagged-frame ingress
rules between releases. Therefore, even if the system can
accommodate the number of VLANs from the earlier release, be aware
that it begins using different ingress rules for tagged frames.
The CoreBuilder 3500 tagged-frame ingress rules vary for 1.2.0,
2.0.0, and 3.0.0. For more information, see the CoreBuilder 3500
Implementation Guide .
The CoreBuilder 9000 tagged-frame ingress rules vary for 2.0.0 to
3.0.0. For more information, see the CoreBuilder 9000
Implementation Guide .
