3.2.4 Trunking Support
Trunking enables you to combine multiple physical FC links to form a single logical link (aggregated port). The aggregated
port’s maximum link speed is the sum of the maximum link speeds of the individual physical links comprising the aggregated
port. For example, an aggregated port comprised of two physical links running at 32Gb/s each will have a potential logical
(aggregate) link speed of 64Gb/s. The actual link speed of the aggregated port depends on the states (active or non-active)
of the individual physical links comprising the aggregated port.
The physical links comprising an aggregated port are referred to as lanes. Only 2-lane and 4-lane aggregated ports are
supported. For LPe35002 adapters, only 2-lane port aggregation is possible. If 2-lane port aggregation is configured on an
LPe35002 adapter, the two physical links are combined to form a single 2-lane aggregated port whose aggregate speed is
potentially 64Gb/s, assuming both physical links are active.
LPe35004 adapters support both 2-lane port aggregation and 4-lane port aggregation. If 2-lane port aggregation is
configured on an LPe35004 adapter, the four physical links on the adapter will be divided among two separate aggregated
ports. The two lowest numbered physical links will form the first aggregated port, and the two highest number physical links
will form the second aggregated port. If 4-lane port aggregation is configured on an LPe35004 adapter, all four physical links
will be combined to form a single 4-lane trunk whose aggregate speed is potentially 128Gb/s, assuming all four links are
active.
NOTE: The following information applies to trunking support:
Trunking is supported only on LPe35000-series adapters.
Before you enable or disable trunking on the Emulex adapter, follow the instructions from Brocade
®
to enable
or disable trunking on the switch.
Dynamic D_Port cannot co-exist with the trunking feature. If trunking is enabled, the firmware automatically
disables Dynamic D_Port.
FA-PWWN cannot co-exist with the trunking feature. If trunking is enabled, the firmware automatically disables
FA-PWWN and Dynamic D_Port.
Trunking is not supported at 8Gb/s speeds, and the link will not come up at this speed.
There are no driver parameters to enable trunking. Trunking is a one-time configuration, and the configuration is performed
through the Emulex HBA Manager application. For more information on configuring trunking, refer to the Emulex HBA
Manager Application User Guide.
When trunking is configured for an adapter, internal loopback and external loopback tests are supported. For more
information on running loopback tests, refer to the Emulex HBA Manager Application User Guide.
You can view the existing trunk links using esxcli elxmgmt.
Following is an example of an LPe35002 adapter, showing 2-lane port aggregation with a single SCSI host.
# esxcli elxmgmt trunkinfo get -w 10:00:00:10:9b:41:73:8c
