Description
Table showing downstream DES keys.
Table of downstream DES Cipher Block Chaining mode information.
Table showing the SID values to be enabled for DES encryption.
Controls which SID entries in the SID table are enabled for encryption. In the above
example, none of the entries are enabled for encryption.
Control register that controls the operating mode of the downstream DES engine.
DES security version register; the range of the version field in the Baseline Privacy
Interface (BPI) extended headers that will be accepted by the hardware. High byte is
upper limit, low byte is lower limit. The Cisco uBR924 will accept versions 0 to 15.
