FIGURE 49 Encryption and compression on 16 Gbps ISLs
The encryption and compression features are designed to work only with E_Ports. Encryption and
compression are also compatible with the following features:
• E_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.
No license is needed to configure and enable in-flight encryption or compression.
Encryption and compression restrictions
• No more than two ports on one ASIC can be configured with encryption, compression, or both.
This restriction equates to a maximum of four ports per FC16-32 or FC16-48 blade, or two
ports per Brocade 6510 switch.
• The number of ports in a trunk is limited to two ports when encryption or compression is
enabled for the trunk.
• 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 are supported.Although VE_Ports, VEX_Ports, EX_Ports, GE ports, FCoE ports,
F_Ports, F_Port trunks, ICL ports, and D_Ports cannot be configured for encryption or
compression, they can exist along the I/O path.
• The encryption feature is not supported in FIPS mode. In-flight encryption is not FIPS
compliant.
• Brocade Network Advisor does not support encryption or compression.
• L!L through any encryption-enabled port or compression-enabled port is not supported.
