Steps for connecting to an SKM or ESKM appliance

NOTE
An SKM/ESKM cluster may have many members, but the Brocade encryption products support only
two as primary and secondary key vaults.
Initializing the Brocade encryption engines
You must perform a series of encryption engine initialization steps on every Brocade encryption
node (switch or blade) that is expected to perform encryption within the fabric.
NOTE
The initialization process overwrites any authentication data and certificates that reside on the node
and the security processor. If this is not a first-time initialization, make sure to export the master key
by running cryptocfg
--exportmasterkey and cryptocfg –export -scp --currentMK before running
--initEE.
Take the following steps to initialize an encryption engine.
1. Log in to the switch as Admin or SecurityAdmin.
2. Zeroize all critical security parameters (CSPs) on the switch by entering the cryptocfg
--zeroizeEE command. Provide a slot number if the encryption engine is a blade.
SecurityAdmin:switch>cryptocfg --zeroizeEE
This will zeroize all critical security parameters
ARE YOU SURE (yes, y, no, n): [no]y
Operation succeeded.
3. Zeroization leaves the switch or blade faulted. Perform the appropriate action depending on
whether the encryption engine is a switch or a blade.
• When the encryption engine is on an encryption switch, reboot the switch.
• When the encryption engine is on an FS8-18 blade, issue the slotpoweroff slot number
command followed by the slotpoweron slot number command.
4. Synchronize the time on the switch and the key manager appliance. They should be within one
minute of each other. Differences in time can invalidate certificates and cause key vault
operations to fail.
5. Initialize the node by entering the cryptocfg
--initnode command. Successful execution
generates the following security parameters and certificates:
• Node CP certificate
• Key Archive Client (KAC) certificate
NOTE
Node initialization overwrites any existing authentication data on the node.
SecurityAdmin:switch>cryptocfg --initnode
This will overwrite all identification and authentication data
ARE YOU SURE (yes, y, no, n): [no] y
Notify SPM of Node Cfg
Operation succeeded.
