Defining a shared uplink set
To define a shared uplink set:
1. Enter the shared uplink set name. The uplink set name can be up to 64 characters in length (no spaces).
2. Use the Add Port cascading menu to add one or more external ports. Only available ports are listed,
and they display the current port link status. Select two or more ports to ensure a high availability
connection.
When using an associated FCoE network, the port link status is not displayed and the selection applies
to all enclosures.
3. Select the speed and duplex (where applicable) of the uplink ports. This setting does not apply if an
FCoE network is defined. Click the pull-down box under Speed/Duplex, and then select a setting.
Half-duplex operation is not supported by the VC-Enet module.
IMPORTANT: Be sure that the uplink interface port speed matches the speed set on the
corresponding network switch port. If using autonegotiation, both ports must be configured to use
autonegotiation or they might not link.
4. Select the Connection Mode (not available for shared uplink sets with an associated FCoE network):
o Auto (recommended)—This mode enables the uplinks to attempt to form aggregation groups using
IEEE 802.3ad link aggregation control protocol, and to select the highest performing uplink as the
active path to external networks.
Aggregation groups require multiple ports from a single VC-Enet module to be connected to a single
external switch that supports automatic formation of LACP aggregation groups, or multiple external
switches that utilize distributed link aggregation. HP has guidelines available for users who wish to
connect to external switches that support distributed link aggregation capabilities.
Multiple aggregation groups may be formed from the ports selected for the network. The highest
performing aggregation group is selected as active, with other aggregation groups and individual
links used as standby connections.
o Failover—If this mode is selected, set the port to Primary or Secondary. Only a single link is used as
the active link to the external networks, with other ports used as standby connections.
5. If the Connection Mode is Auto, select the LACP Timer:
o Domain Default—If this mode is selected, the network uses the domain-wide LACP timer
configuration setting. The current setting is displayed as part of the radio button label. See the
descriptions for Short and Long.
o Short—If this mode is selected, VC requests short (every 1 second) LACP control messages on a LAG
that is formed with the uplink ports.
o Long—If this mode is selected, VC requests long (every 30 seconds) LACP control messages on a
LAG that is formed with the uplink ports.
6. Create the associated FCoE networks that will use this shared uplink. For more information, see
"Defining an FCoE network (on page 134 )."
