Details
Check Text (C-220501r961506_chk)
Review the Cisco switch configuration to verify that it is compliant with this requirement as shown in the example below:
snmp-server user NETOPS auth sha 5Er23@#as178 priv aes-128 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
snmp-server host 10.1.48.10 traps version 3 priv NETOPS
Encryption used by the SNMP users can be viewed via the show snmp user command as shown in the example below:
SW1# show snmp user
______________________________________________________________
SNMP USERS
______________________________________________________________
User Auth Priv(enforce) Groups acl_filter
____ ____ ___________ ______ __________
NETOPS sha aes-128 network-operator
If the Cisco switch is not configured to encrypt SNMP messages using a FIPS 140-2 approved algorithm, this is a finding.
Fix Text (F-22205r940005_fix)
Configure the Cisco switch to encrypt SNMP messages using a FIPS 140-2 approved algorithm as shown in the example below:
SW1(config)# snmp-server user NETOPS auth sha xxxxxxxxxxxxx priv aes-128 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
SW1(config)# snmp-server host 10.1.48.10 traps version 3 priv NETOPS
