Re-authenticating E_Ports, Viewing the current authentication parameter settings for a switch

Page 176 highlights

7 Authentication policy for fabric elements Viewing the current authentication parameter settings for a switch 1. Log in to the switch using an account assigned to the admin role. 2. Enter the authUtil --show. Example of output from the authUtil --show command AUTH TYPE HASH TYPE GROUP TYPE fcap,dhchap sha1,md5 0, 1, 2, 3, 4 Switch Authentication Policy: PASSIVE Device Authentication Policy: OFF Setting the authentication protocol used by the switch to DH-CHAP 1. Log in to the switch using an account assigned to the admin role. 2. Enter the authUtil --set -a dhchap command. Example of setting the DH-CHAP authentication protocol switch:admin> authutil --set -a dhchap Authentication is set to dhchap. When using DH-CHAP, make sure that you configure the switches at both ends of a link. NOTE If you set the authentication protocol to DH-CHAP, have not yet configured shared secrets, and authentication is checked (for example, you enable the switch), switch authentication fails. 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 private, 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 134 Fabric OS Administrator's Guide 53-1001336-01

Authentication policy for fabric elements

Viewing the current authentication parameter settings for a switch
1.
Log in to the switch using an account assigned to the admin role.
2.
Enter the
authUtil
--

Example of output from the authUtil --show command
AUTH TYPE
HASH TYPE
GROUP TYPE
--------------------------------------
fcap,dhchap

Switch Authentication Policy: PASSIVE
Device Authentication Policy: OFF
Setting the authentication protocol used by the switch to DH-CHAP
1.
Log in to the switch using an account assigned to the admin role.
2.
Enter the
authUtil
--
set -a dhchap
command.
Example of setting the DH-CHAP authentication protocol
switch:admin>
authutil --set -a dhchap
Authentication is set to dhchap.
When using DH-CHAP, make sure that you configure the switches at both ends of a link.
NOTE
If you set the authentication protocol to DH-CHAP, have not yet configured shared secrets, and
authentication is checked (for example, you enable the switch), switch authentication fails.
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 private, 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
–-

command.
Example for specific ports on the switch
