HP StorageWorks Fabric OS 6.1.x administrator guide (5697-0234, November 2009)

116 Configuring advanced security features
Aborting all uncommitted changes
Use the secPolicyAbort command to abort all ACL policy changes that have not yet been saved.
To abort all unsaved changes:
1. Connect to the switch and log in using an account assigned to the admin role.
2. Type the secPolicyAbort command:
switch:admin> secpolicyabort
Unsaved data has been aborted.
All changes since the last time the secPolicySave or secPolicyActivate commands were
entered are aborted.
Configuring the authentication policy for fabric elements
By default, Fabric OS 6.1.x uses DH-CHAP or FCAP protocols for authentication. These protocols use
shared secrets and digital certificates, based on switch WWN and public key infrastructure (PKI)
technology, to authenticate switches. Authentication automatically defaults to FCAP if both switches are
configured to accept FCAP protocol in authentication. To use FCAP on both switches, PKI certificates have
to be installed.
NOTE: The fabric authentication feature is available in base Fabric OS. No license is required.
You can configure a switch with Fabric OS 5.3.0 or later to use Diffie-Hellman challenge handshake
authentication protocol (DH-CHAP) for device authentication. Use the authUtil command to configure
the authentication parameters used by the switch. When you configure DH-CHAP authentication, you also
must define a pair of shared secrets known to both switches as a secret key pair. Figure 3 on page 117
illustrates how the secrets are configured. A secret key pair consists of a local secret and a peer secret. The
local secret uniquely identifies the local switch. The peer secret uniquely identifies the entity to which the
local switch authenticates. Every switch can share a secret key pair with any other switch or host in a
fabric.
In order to use DH-CHAP authentication, a secret key pair has to be configured on both switches. To use
FCAP on both switches, PKI certificates have to be installed. You can use the command
authutil –-set <fcap|dhchap> to set the authentication protocol which can then be verified using
the command authutil –-show CLI.
NOTE: The standards-compliant DH-CHAP and FCAP authentication protocols are not compatible with
the SLAP protocol that was the only protocol supported in earlier Fabric OS releases 4.2, 4.1, 3.1, 2.6.x.
Fabric OS 6.1.x switch-to-switch authentication implementation is fully backward compatible with 3.2, 4.2,
4.4, 5.0, 5.1, 5.2, and 5.3.0.
Use secAuthSecret to set a shared secret on the switch. When configured, the secret key pair are used
for authentication. Authentication occurs whenever there is a state change for the switch or port. The state
change can be due to a switch reboot, a switch or port disable and enable, or the activation of a policy.
