Caution

The non-802.1Q-Compliant Multiple VLAN mode does not protect
the switch from VLAN leakage. If the switch receives a packet on the
uplink port containing a destination MAC address that is not in the
MAC address table, the switch broadcasts the packet out all ports,
except the uplink port. This means that all end nodes on the switch
receive the packet.

Multiple VLAN

Modes and the

Management

VLAN

Although both multiple VLAN modes support remote management of
the switch via a management VLAN, the management VLAN is restricted
to one VLAN. It cannot be changed. In the 802.1Q-compliant mode, the
management VLAN is the VLAN where the uplink port is an untagged
member. In the non-802.1Q compliant mode, the management VLAN is
the VLAN that contains all of the ports.

For background information in the management VLAN, refer to
Specifying a Management VLAN on page 433.
