Preparing the switch for FIPS
D
• If the switch is set for LDAP, refer to the instructions in “Setting up LDAP for FIPS mode” on
page 536.
3. Optional: Set the authentication protocols.
a. Type the following command to set the hash type for MD5 which is used in authentication
protocols DHCHAP and FCAP:
authutil --set -h sha1
b. Set the DH group to 1 or 2 or 3 or 4 using authUtil --set -g <n>, where the DH group is
represented by <n>.
4. Install the LDAP CA certificate on the switch and Microsoft Active Directory server. Refer to the
instructions “LDAP certificates for FIPS mode” on page 538.
5. Block Telnet, HTTP, and RPC using the ipfilter policy command.
You will need to create an IPFilter policy for each protocol.
a. Create an IP filter rule for each protocol, see “Creating an IP Filter policy” on page 141.
b. Add a rule to the IP filter policy, see “Adding a rule to an IP Filter policy” on page 145. You
can use the following modifications to the rule:
ipfilter --addrule <policyname> -rule <rule_number> -sip <source_IP> -dp
<dest_port> -proto <protocol> -act <deny>
• -sip option can be given as any
• -dp option for the port numbers for Telnet, HTTP, and RPC are 23, 80, and 898
respectively
• -proto option should be set to tcp
c. Activate the IP filter policy, see “Activating an IP Filter policy” on page 142.
d. Save the IP filter policy, see “Saving an IP Filter policy” on page 142.
Example
ipfilter --createrule http_block_v4 --type ipv4
ipfilter --addrule http_block_v4 -rule 2 -sip any -dp 80 -proto tcp -act deny
ipfilter --activate http_block_v4
ipfilter --save http_block_v4
6. Type the following command to block access to the boot PROM:
fipscfg –-disable bootprom
