feature is promoted to the team’s Advanced Settings tab with the lowest size configured for the
team members. For example, if there are two adapters, one configured for 4088 bytes and the
other for 9014 bytes, and they are teamed, the Maximum Frame Size feature is set to 4088 bytes.
A setting of 1514 bytes is equal to Jumbo Frames being disabled. Maximum Frame Size greater
than 1514 is equal to Jumbo Frames being enabled. Jumbo Frames are supported on NC Series
gigabit adapters only. In addition, the specified Maximum Frame Size in HP Integrity Network
Adapter Teaming does not include the four-byte Cyclic Redundancy Check (CRC) portion of an
Ethernet frame. Some switch settings do include the CRC portion in their Jumbo Frame Size
configuration. Therefore, it may be necessary to increase the switch’s Jumbo Frame Size setting
by four bytes in order for Jumbo Frames to work correctly.
802.1Q Virtual Local Area Networks (VLAN)
The NCU supports the configuration of VLANs on standalone HP Integrity Network adapters
and on HP Integrity Network adapter teams. This allows a network adapter or a team to belong
to more than one VLAN at the same time. When multiple VLANs are configured on the same
network adapter or team, 802.1Q VLAN tagging is enabled and used to mark every transmitted
frame with a VLAN identifier (number between 1 and 4094). The use of VLAN tagging requires
the support of the network infrastructure and/or the receiving network device.
For teams configured to use VLANs, receive validation heartbeats are only transmitted on a
single VLAN. This means that if four VLANs are configured on the team and the VLAN configured
for receive validation heartbeats is 20, the teaming driver will use VLAN 20 for transmitting
heartbeats between team members.
Much like deploying SLB, the use of VLANs requires the switch or switches to be configured
properly. Every team member’s switch port must be configured with the same VLAN
configuration. This means that if a team is to operate on four different VLANs, every team
member must have all four VLANs configured on their respective switch port.
The maximum configurable VLANs per team is 64. The valid VLAN number range per VLAN
is 1 to 4094.
Example of VLAN tagging used with HP Integrity Network Adapter Teaming (refer to
Figure 4-27):
• Four NICs teamed together as a single virtual NIC using HP Integrity Network Adapter
Teaming
• Two VLANs configured on top of the virtual NIC to create two virtual interfaces
• Provides the same functionality to the OS as having two NICs installed but provides for
fault tolerance and load balancing across four NICs
