ClearLink Diagnostics: D_Port Enhancements
FOS v7.2 adds the following D_Port enhancements:
 Enhancement to D_Port test results
Starting with FOS v7.2 complete results of the D_Port tests will be available on the responder switch
as well. Prior to FOS v7.2, D_Port test results on the D_Port responder switch did not include optical
and remote loopback test results. Complete results were only available on the D_Port initiator switch.
 D_Port support between Brocade 16G HBA and Brocade 16G Access Gateway.
 Dynamic D_Port support between Brocade 16G HBA and Brocade 16G switch
 With this enhancement users do not need to explicitly configure D_Port on the switch.
 A switch port enters D_Port mode upon request from the HBA, D_Port tests then get
performed and the switch port reverts back to the normal mode after the D_Port tests are
completed.
 This enhancement significantly reduces the operational overhead by eliminating several
manual configuration steps.
Access Gateway Enhancements
FOS v7.2 supports the following Access Gateway enhancements:
 D_Port diagnostics support on the links between Brocade 16G HBA and Brocade 16G Access Gateway
to assess SFP and cable health.
 Detect and prevent duplicate PWWN at the time of login.
Encryption Platform (BES/FS8-18) Enhancements
FOS v7.2 introduces the following enhancements for the encryption platforms:
 KMIP Support for TEKA (Thales e-Security Key Authority)
 Thin Provisioning support for IBM XIV and EMC VMAX
FICON Enhancements
FOS v7.2 implements the following FICON enhancements:
 Added the ability for the CUP Diagnostics to determine the firmware version of all the switches in the
fabric which allows interoperability with FOS v7.1
 Implemented a new Command Reject Error Code provided by IBM to help define “Fabric Errors”.
Miscellaneous Enhancements
FOS v7.2 supports several useful enhancements across various feature categories:
 FOS v7.2 allows 10G speed configuration on all ports of a 16G FC blade and 16G switch (6510, 6520
only)
 Provides more flexibility to the end users to enable 10G capability on any port
 Also provides more flexibility to enable encryption/compression on 10G ports.
Pre-FOS v7.2 limited 10G FC support to only the first 8 ports of a 16G switch or a 16G blade.
This also limited the ability to enable encryption/compression to only two of those first 8
ports due to restrictions on the number of ports supported per ASIC. By removing this
restriction, FOS v7.2 allows users to enable more 10G FC ports for encryption and
compression by spreading them across multiple ASICs.
