Preparing the switch for FIPS
D
Enabling FIPS mode
1. Log in to the switch using an account assigned the admin or securityAdmin role.
2. Optional: Select the appropriate method based on your needs:
•
If the switch is set for RADIUS , modify each server to use only peap-mschapv2 as the
authentication protocol using the aaaConfig
--
change or aaaConfig
--
remove command.
•
If the switch is set for LDAP , refer to the instructions in “Setting up LDAP for FIPS mode” on
page 524.
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 526.
5. Block Telnet, HTTP, and RPC using the ipfilter policy command.

b. Add a rule to the IP filter policy, see “Adding a rule to an IP Filter policy” on page 157. 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

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
