Virtual Connect networks 128
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 129)."
7. Create the Associated Networks that will use this shared uplink:
a. Click Add above the table.
-or-
Right-click the header row in the Associated Networks table to display a menu, and then select Add.
b. To add a single associated network:
i. Select the a single Associated Network radio button.
ii. Enter the name of the network.
iii. Enter the number for the VLAN ID (1 to 4094) for that network as defined by the network
administrator and as configured on the external Ethernet switch.
iv. Select whether to enable (checked) or disable (unchecked) native VLAN. Only one network per
shared uplink set can be selected as the native VLAN. See "Shared uplink sets and VLAN
tagging (on page 85)."
v. Skip to step d.
c. To add multiple associated networks:
i. Select the multiple Associated Networks radio button. Creating multiple associated networks in
bulk allows for a shorter setup time. All networks created in bulk share the same settings. These
networks can be edited individually after they are created.
ii. Enter the name of the networks. The networks that are created together share a common naming
convention of a prefix, the VLAN ID, and a suffix. The prefix and suffix are both optional.
iii. Enter comma separated VLAN IDs, VLAN ID ranges, or a mixture of both. For example, enter
3,9,15-20 to create eight associated networks with the VLAN IDs 3, 9, 15, 16, 17, 18, 19,
and 20.
d. To add a color to the network, select a color from the Color pull-down menu. The network color is
used as visual identifier for the network within VCM.
