Important Notes
In-flight Encryption and Compression
• Fabric OS 8.0.1 does not support in-flight encryption on Brocade G620 or X6 directors. The CLI
command for port configuration for in-flight encryption is blocked in Fabric OS 8.0.1.
• In-flight compression is supported in FOS v8.0.1 on Brocade G620 and X6 directors.
• In-flight encryption and compression are supported on 6510, 6520, and DCX 8510 platforms.
ClearLink Diagnostics (D_Port)
• Fabric OS 8.0.1 supports D_Port tests between two Brocade switches and between Brocade
switches and Gen 5 (16 Gbps) and Gen 6 (32 Gbps) Fibre Channel Adapters from QLogic and
Emulex. Following are specific adapter models and driver versions tested by Brocade with
Fabric OS v8.0.1 for ClearLink.

• The D_Port long duration test can only be run on one port at a time.
• Long-duration optical loopback tests can be run on only one port at a time.
• Long-duration electrical loopback tests are not supported.
Forward Error Correction (FEC)
• FEC is mandatory with Gen 6 Fibre Channel operating at 32Gbps. This means that the
portCfgFec command only applies to ports running at 16Gbps or 10Gbps.
• FEC capability is not supported with all DWDM links. This means that FEC may need to be
disabled on 16Gbps or 10Gbps ports when using DWDM links with some vendors. This is done
using the portCfgFec command. Failure to disable FEC on these DWDM links may result in link
failure during port bring up. Refer to the Brocade Fabric OS 8.x Compatibility Matrix for
supported DWDM equipment and restrictions on FEC use.
Access Gateway
• The 32G links with 4x32G QSFP ports (port 48–port 63) do not have default mappings. These
ports will be disabled by default when a Brocade G620 is enabled for Access Gateway mode or
the configuration set to default.
• The Brocade G620 does not support cascaded Access Gateway topology, i.e., it cannot be a
core AG that provides fabric access to an edge AG.
Ingress Rate Limiting
• Fabric OS 8.0.1 does not support ingress rate limiting on Brocade G620 or X6.
