Authentication policy for fabric elements

WARNING: This is a disruptive operation that requires a reboot to take
effect.
All EX ports will be disabled upon reboot.
Would you like to continue [Y/N] y
switch:admin> authutil --authinit 2,3,4
CAUTION
If data input has not been completed and a failover occurs, the command is terminated without
completion and your entire input is lost.
If data input has completed, the enter key pressed, and a failover occurs, data may or may not be
replicated to the other CP depending on the timing of the failover. Log in to the other CP after the
failover is complete and verify the data was saved. If data was not saved, run the command
again.
Example of setting the policy to active mode
switch:admin> authutil --policy -sw active
Warning: Activating the authentication policy requires
either DH-CHAP secrets or PKI certificates depending
on the protocol selected. Otherwise, ISLs will be
segmented during next E-port bring-up.
ARE YOU SURE (yes, y, no, n): [no] y
Auth Policy is set to ACTIVE

Re-authenticating E_Ports

Use the command authUtil to re-initiate the authentication on selected ports. It provides flexibility
to initiate authentication for specified E_Ports, a set of E_Ports, or all E_Ports on the switch. This
command does not work on loop, NPIV and FICON devices. The command authUtil can re-initiate
authentication only if the device was previously authenticated. If the authentication fails because
shared secrets do not match, the port is disabled.
This command works independently of the authentication policy; this means you can initiate the
authentication even if the switch is in PASSIVE mode. This command is used to restart
authentication after changing the DH-CHAP group, hash type, or shared secret between a pair of
switches.
ATTENTION
This command may bring down E_Ports if the DH-CHAP shared secrets are not installed correctly.
1. Log in to the switch using an account assigned to the admin role.
2. Enter the authUtil –-authinit command.
Example for specific ports on the switch
switch:admin> authutil –-authinit 2,3,4
Example for all E_Ports on the switch
switch:admin> authutil –-authinit allE
Example for enterprise-class platforms using the slot/port format
switch:admin> authutil –-authinit 1/1, 1/2
