Fabric OS 6.1.1 administrator guide 121
Supported HBAs
The following HBAs support authentication:
Emulex LP11000 (Tested with Storport Miniport 2.0 windows driver)
Qlogic QLA2300 (Tested with Solaris 5.04 driver)
Authentication protocols
Use the authUtil command to perform the following tasks:
Display the current authentication parameters
Select the authentication protocol used between switches
Select the Diffie-Hellman (DH) group for a switch
Run the authUtil command on the switch you want to view or change. Options for specifying which DH
group you want to use include:
00 – DH Null option
01 1024 bit key
02 – 1280 bit key
03 – 1536 bit key
04 – 2048 bit key
This section illustrates the use of the authUtil command to display the current authentication parameters
and to set the authentication protocol to DH-CHAP. See the Fabric OS command reference for details on
the authUtil command.
To view the current authentication parameter settings for a switch:
1. Log in to the switch using an account assigned to the admin role.
2. On a switch running Fabric OS 6.0 or later, issue the authUtil --show command.
Output similar to the following is displayed:
AUTH TYPE HASH TYPE GROUP TYPE
--------------------------------------
fcap,dhchap sha1,md5 0, 1, 2, 3, 4
Switch Authentication Policy: PASSIVE
Device Authentication Policy: OFF
To set 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. On a switch running Fabric OS 4.x or 5.x, enter authUtil --set -a dhchap; on a switch running
Fabric OS 3.x, enter authUtil "
--set -a dhchap".
Output similar to the following is displayed:
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.
E_Port re-authentication
Use the command authutil to re-initiate the authentication on selected ports. It provides flexibility to
initiate authentication for specified E_Ports, set of E_Ports, and all E_Ports on the switch. This command will
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.
