TCP/UDP Checksum Offload (IPv4)
Allows configuring checksum offload for the IPv4 protocol.
Disable.
Disables checksum offload.
Rx Enabled.
Enables receive TCP/IP/UDP checksum offload.
Tx Enabled.
Enables transmit TCP/IP/UDP checksum offload.
TX & Rx Enabled (default).
Enables transmit and receive TCP/IP/UDP checksum
offload.
Priority & VLAN
Allows enabling both the prioritization of network traffic and VLAN tagging. VLAN tagging only
occurs when the VLAN ID setting is configured with a value other than 0 (zero).
Priority & VLAN Enabled (default)
. Allows for packet prioritization and VLAN
tagging.
Priority & VLAN Disabled
. Prevents packet prioritization and VLAN tagging.
Priority Enabled
. Allows packet prioritization only.
VLAN Enabled
. Allows VLAN tagging only.
Note: If an intermediate driver is managing the network adapter for VLAN tagging,
the
Priority & VLAN Disabled
and
Priority Enabled
settings should not be used.
Use the
Priority & VLAN Enabled
setting and change the
VLAN ID
to 0 (zero).
VLAN ID
Enables VLAN tagging and configures the VLAN ID when
Priority & VLAN Enabled
is
selected as the
Priority & VLAN
setting. The range for the VLAN ID is 1 to 4094 and must
match the VLAN tag value on the connected switch. A value of 0 (default) in this field disables
VLAN tagging.
Risk Assessment of VLAN Tagging through the NDIS Miniport Driver
Broadcom's NDIS 6.0 miniport driver provides the means to allow a system containing a
Broadcom adapter to connect to a tagged VLAN. On Windows XP systems, this support
was only provided through the use of an intermediate driver (e.g., Broadcom Advanced
Server Program - BASP). Unlike BASP, however, the NDIS 6 driver's support for VLAN
participation is only for a single VLAN ID.
