8. From the Automatic VLAN Creation pull-down menu, select
Enable to automatically create a VLAN each time the port
receives a frame from an unknown VLAN.
9. From the VTP Snooping pull-down menu, select Enable or
Disable. When enabled, the switch port participates in the
Cisco VTP protocol and allows VTP Snooping to run a a
reduced number of trunk port. The default value is Enable.
10. From the Allow Learning pull-down menu, select Disable
to stop the port’s learning of new addresses. This feature can
be useful for security. Selecting Enable allows the port to
learn new addresses.
Table 2-6. VLAN Binding Options
Option Definition
Static Assigns VLAN membership manually.
Bind to All Binds this port to all VLANs known to the
switch. This is an appropriate mode for switch-
to-switch connections.
Note: When a tagged IEEE 802.1Q packet
arrives on a port that is set to bind to all
and the VLAN does not exist on the
switch, the packet is forwarded on to the
VLAN assigned to the port default VLAN
for that port. To prevent unintended
forwarding of unknown VLAN traffic to
the port’s default VLAN, configure the
port default VLAN to Discard. The
automatic VLAN creation feature does
not work if the port’s default VLAN is
the discard VLAN, because the switch
does not learn for this VLAN.
Bind to Received Binds this port to any VLAN it receives traffic
from.
Note: If Automatic VLAN Creation is enabled,
the port binds to previously unknown
VLANs, and a VLAN entry is added to
the switch VLAN table. If Automatic
VLAN Creation is disabled, the port does
not bind to any VLAN unknown to the
switch.
