FIGURE 179 Fibre Channel Security Protocol Configuration dialog box

3.Configure the following parameters on the Fibre Channel Security Protocol Configuration dialog box:

a.Select the Enable Authentication check box to enable the authentication policy.

If authentication is enabled, the port attempts to negotiate with the switch. If the switch does not participate in the authentication process, the port skips the authentication process.

b.In the Algorithm list, select one of the following options:

•MD5 - A hashing algorithm that verifies a message’s integrity using Message Digest version 5. MD5 produces a 128-bit digest and is the required authentication mechanism for LDAP v3 servers.

•SHA1 - A secure hashing algorithm that computes a 160-bit message digest for a data file that is provided as input.

•MD5SHA1 - Similar to the MD5 hashing algorithm, but used for DH-CHAP authentication.

•SHA1MD5 - Similar to the SHA1 hashing algorithm, but used for DH-CHAP authentication.

c.Enter a secret in the CHAP Secret field. Enter the secret again in the Retype Secret field.

The length of the secret must be from 8 through 41 characters in length. The Secret field cannot be blank.

d.From the Group list, select DHNULL as the DH-group type value.

4.Click OK to save the changes and close the dialog box. FC-SP settings are also applied to the attached switch.
