Creating VLANs
and Frame Tags
Parameters
VLANs are created automatically by the switch reading the VLAN tag of all
ingress IEEE 802.1Q and Multi-Layer tagged frames. The switch then
creates a new VLAN for every new VLAN tag identified. However, if the
parameter for Frame Tags is set to Ignore, the switch will ignore the
VLAN tags on ingress frames. The switch assumes that all ingress frames
belong to the ‘Port VLAN’. Therefore, no new VLANs will ever be
created automatically.

Automatic Binding
of VLANs to Ports
of VLANs to Ports
When a VLAN is either manually or automatically created, the software
may automatically bind the VLAN to a port depending on the setting of the
‘Trunk Mode’ parameter assigned to the port.

Configuring MAC Address Lock and Intrusion Detection
Overview
The MAC Address Lock feature filters frames that do not match the static
MAC address that is assigned to a port. If you enable MAC Address Lock,
you can also enable Intrusion Detection, which generates trap messages that
identify intruding (unknown) source addresses.
MAC address that is assigned to a port. If you enable MAC Address Lock,
you can also enable Intrusion Detection, which generates trap messages that
identify intruding (unknown) source addresses.
The switch stores a history of 64 intruding source MAC addresses in a
software buffer. One intruding source MAC address is stored and one trap
message is generated per the intrusion trap timer setting. Once a MAC
address is stored and the trap is generated, the switch does not send another
trap for the address until it is cleared from the buffer.

* Note: The default setting for the intrusion trap timer is 1800 seconds
(30 minutes). The valid range for the timer is 60 to 1800
