FIGURE 54 Encryption and compression on 16 Gbps ISLs
Supported ports for in-flight encryption and compression
The in-flight encryption and compression features are supported only on E_Ports and EX_Ports, and
only on the Brocade 6510 and 6520 switches, 16 Gbps embedded switches, and the Brocade DCX
8510 Backbone family.
The ports can run at any speed, but must be 16 Gbps-capable.
Encryption and compression are also compatible with the following features:
• E_Ports or EX_Ports with trunking, QoS, or long distance features enabled.
• Flow control modes: R_RDY, VC_RDY, and EXT_VC_RDY.
• XISL ports in VF mode.
• FCP data frames and non-FCP data frames except ELS and BLS frames.
FCP data frames are of Type = 0x8. For encryption, R_CTL = 0x1 and R_CTL = 0x4 are supported.
For compression, only R_CTL = 0x1 is supported.
Non-FCP data frames are of Type != 0x8. Non-FCP frames with ELS/BLS (R_CTL == 0x2 || R_CTL ==
0x8) are not supported.
In-flight encryption and compression restrictions
• Ports must be 16 Gbps-capable, although port speed can be any configurable value.
• The number of ports that can be configured is dynamic based on port speed. Refer to
Table 77 on
page 409 for specific details about the number of ports supported for encryption and compression.
• The devices at either end of the ISL must run Fabric OS 7.0.0 or later software.
• Only E_Ports, EX_Ports, and XISL ports (in VF mode) support encryption or compression. ICL ports
do not support encryption or compression.
• In-flight encryption is not FIPS certified.
