FIGURE 49
Encryption and compression on 16 Gbps ISLs
The encryption and compression features are designed to work only with E_Ports, EX_Ports, and XISL
ports (in VF mode). 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.
NOTE
No license is needed to configure and enable in-flight encryption or compression.
Encryption and compression restrictions
•
Configuration is dynamic based on port speed. See Table 62 on page 395 for specific details
about the number of ports supported for encryption and compression.
•
Ports must be 16 Gbps capable, although port speed can be any configurable value.
•
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 currently support encryption or compression.
•
Encryption is not supported in FIPS mode, as in-flight encryption is not FIPS compliant.
