HP OneView - Manual (Page 142)

The switch ports for data center network switches that connect to the Virtual Connect interconnect
modules must be configured as follows:
•
Spanning tree edge (because the Virtual Connect interconnect modules appear to the switch
as access devices instead of switches).
•
VLAN trunk ports (tagging) to support the VLAN IDs included in the uplink set that connects
to switch port.
For example, if you configure an uplink set, prodUS, that includes the production networks
prod 1101
through prod 1104 to use the X2 ports of the interconnects in bay 1 and bay
2 of Enclosure 1, then the data center switch ports that connect to those X2 ports must be
configured to support VLAN IDs 1101, 1102, 1103, and 1104.
•
If multiple uplinks in an uplink set connect the same interconnect to the same data center switch,
to ensure that all the uplinks in the uplink set are active, you must configure the data center
switch ports for LACP (Link Aggregation Control Protocol) in the same LAG (Link Aggregation
Group). As part of the LACP negotiation to form a LAG, the interconnect sends a request for
the frequency of control messages. The frequency can be short or long. Short is every 1 second
with a 3 second timeout. Long is every 30 seconds with a 90 second timeout.
Also consider the type of network traffic and if you are creating an active/standby or active/active
configuration .
