For compatibility purposes, allows the module to observe previous VLAN
resource usage and tagged-frame ingress rules for upgrades from Release
2.x to 3.x.

Important Considerations
Use this command only if you upgrade your module and it reports an
error after reaching the VLAN resource limit during a power up with a
serial-port console connection. During the upgrade, the difference in
resource usage and modes of tagging could cause the later release to
use more VLAN resources than did the earlier release, thereby causing
a decrease in the total number of allowable VLANs.
If the module reaches the VLAN resource limit during the upgrade, it
displays an error message to identify the index of the VLAN that it was
unable to create. The module removes all bridge ports from the VLAN
that it could not restore from NV data but does maintain the
previously stored NV data.
The difference in VLAN resource usage is based on the following:
In Release 2.0.0, all bridge ports were not VLAN aware (tagging
aware) unless they were assigned to a VLAN that has one or more
tagged ports. This behavior is associated with the VLAN aware

already defined, the module prompts you to reboot to put the new
mode into effect.
As of Release 3.0.0, all bridge ports become VLAN aware after a
software update or after an NV data reset and do not have to be
explicitly tagged in order to forward tagged frames. This behavior
is associated with the default VLAN aware mode of

The VLAN aware mode reflects the difference in tagged-frame
ingress rules between releases. Therefore, even if the module can
accommodate the number of VLANs from the earlier release, be
aware that it begins using different ingress rules for tagged frames.
