FIGURE 57 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, 6520,
G620 switches, and 7840 extension switches, 16 Gbps Blade Server SAN I/O Modules, DCX 8510 Backbones and X6 Directors.
The ports can run at any speed, but must be 16 Gbps-capable or 32 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.
