IBM Netfinity 10/100 Ethernet Adapters, Installation Manual

Page: 52 / 70

v
The adapters on these devices must support 802.1p (adapters using the Intel
82558 or higher Ethernet controller). All Netfinity 10/100 Ethernet Adapters
support 802.1p.
v
The adapter cannot be assigned to an adapter team.
v
If you are setting up VLANs and packet tagging on the same adapter,
802.1p/802.1Q Tagging must be Enabled on the IBMSet Advanced tab.
High Priority Queue
If your network infrastructure devices do not support IEEE 802.1p or you are not
sure, you can still define filters and send packets as high priority. While High Priority
Queue (HPQ) does not provide the precise priority levels of 802.1p tagging, it does
assign traffic as either high or low priority and sends high priority packets first.
Therefore, if there are multiple applications on a system sending packets, the
packets from the application with a filter are sent out first. HPQ does not change
network routing, nor does it add any information to the packets.
To assign HPQ, you can specify it using Priority Packet when you create or assign
a filter.
To effectively use HPQ tagging, the adapter cannot be assigned to an adapter
team.
For more information on Priority Packet, refer to the related white papers on IBM’s
