YML827 Rev1
The stacking switches interchange VLAN information through the Giga ports which are set to
tagged members by “Stacking Tag VLAN”. New VLANs should keep their Giga ports tagged.
Since the master switch holds all VLAN group information, the master switch should have the right
to access the new VLAN by adding at least one Giga port to its tagged member. An exclusion of
all master switch ports leads to unmanageability on this VLAN, for the master switch has no such
VLAN in its internal table.
