Chapter 5 Configuring the Adapter and Installing Drivers
20
The requirements for effectively using IEEE 802.1p tagging
are:
• The other devices receiving and routing 802.1p
tagged packets must support 802.1p.
• The adapters on these devices must support 802.1p
(adapters using the 82558 or later Ethernet
controller). All HP NetServer 10/100 adapters
support 802.1p.
• The adapter(s) cannot be assigned to an adapter
team.
• If you’re setting up VLANs and packet tagging on
the same adapter, you must select the 802.1p/802.1Q
Tagging and the Enable option on the HPSet
Advanced tab.
High Priority Queue
If your network infrastructure devices don’t support IEEE
802.1p or you’re not sure, you can still define priority filters
and send packets as high priority. While High Priority Queue
(HPQ) doesn’t 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 priority filter are sent out first. HPQ doesn't
change network routing, or add any information to the packets.
To assign HPQ, you can specify it using Priority Packet when
you create or assign a priority filter.
To effectively use HPQ tagging, the adapter(s) cannot be
assigned to an adapter team.
