Host security authentication 3
3. Configure the following parameters on the Port Security Authentication tab:
a. Select the Enable Authentication check box to enable or disable 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. Type and retype the secret.
The maximum length of the secret is 63 bytes. The default secret for each interface is its
port world wide name (PWWN) without the colons; for example, 0102030405060708.
Select the algorithm type from the list:
•MD5 - A hashing algorithm that verifies a message’s integrity using Message Digest
version 5.
•SHA1 - A secure hashing algorithm that computes a 160-bit message digest for a data
file that is provided as input.
•MD5SH1 - 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. Select DHNULL as the group value (this is the only group that is supported).
4. Click Apply to apply the changes.
5. Click OK to save the changes and close the dialog box.
Configuring security authentication using the BCU
Enter the following commands to display or configure security authentication for the ports:
•bcu auth --algo <port_id> <md|sha1|ms|sm>
•bcu auth --policy <port_id> {on|off}
•bcu auth --secret <port_id> “secret_string”
•bcu auth --show <port_id>
•bcu auth --stats <port_id>
•bcu auth --statsclr <port_id>
Refer to “auth” on page 128 for details about these commands.
