2. Select one of the following Link Speed options for the selected port. Not all
speed selections are available on all adapters.
Auto Negotiated enables Auto Negotiation mode on the port. FEC
mode selection is not available for this speed mode.
1 Gbps enables 1GbE fixed speed mode on the port. This mode is
intended only for 1GbE interfaces and should not be configured for
adapter interfaces that operate at other speeds. FEC mode selection is
not available for this speed mode. This mode is not available on all
adapters.
10 Gbps enables 10GbE fixed speed mode on the port. This mode is
not available on all adapters.
25 Gbps enables 25GbE fixed speed mode on the port. This mode is
not available on all adapters.
SmartAN (Default) enables FastLinQ SmartAN
™
link speed mode on
the port. No FEC mode selection is available for this speed mode. The
SmartAN setting cycles through all possible link speeds and FEC
modes until a link is established. This mode is intended for use only
with 25G interfaces. This mode is not available on all adapters.
3. For NIC + RDMA Mode, select either Enabled or Disabled for RDMA on
the port. This setting applies to all partitions of the port, if in NPAR mode.
4. FEC Mode is visible when 25 Gbps fixed speed mode is selected as the
Link Speed in Step 2. For FEC Mode, select one of the following options.
Not all FEC modes are available on all adapters.
None disables all FEC modes.
Fire Code enables Fire Code (BASE-R) FEC mode.
Reed Solomon enables Reed Solomon FEC mode.
Auto enables the port to cycle through None, Fire Code, and Reed
Solomon FEC modes (at that link speed) in a round-robin fashion,
until a link is established.
5. The RDMA Protocol Support setting applies to all partitions of the port, if in
NPAR mode. This setting appears if the NIC + RDMA Mode in Step 3 is set
to Enabled. RDMA Protocol Support options include the following:
RoCE enables RoCE mode on this port.
iWARP enables iWARP mode on this port.
iWARP + RoCE enables iWARP and RoCE modes on this port. This is
the default. Additional configuration for Linux is required for this option
as described in “Configuring iWARP and RoCE” on page 182.
