Fix Recommendation

Configure the Cisco switch to encrypt SNMP messages using a FIPS 140-2 approved algorithm as shown in the example below:

SW4(config)#snmp-server group V3GROUP v3 priv read V3READ write V3WRITE
SW4(config)#snmp-server user V3USER V3GROUP v3 auth sha xxxxxx priv aes 256 xxxxxx

Check Contents

Review the Cisco switch configuration to verify that it is compliant with this requirement as shown in the example below:

snmp-server group V3GROUP v3 priv read V3READ write V3WRITE
snmp-server view V3READ iso included
snmp-server view V3WRITE iso included
snmp-server host x.x.x.x version 3 auth V3USER

Encryption used by the SNMP users can be viewed via the show snmp user command as shown in the example below:

R4#show snmp user

User name: V3USER
Engine ID: 800000090300C2042B540000
storage-type: nonvolatile active
Authentication Protocol: SHA
Privacy Protocol: AES256
Group-name: V3GROUP

If the Cisco switch is not configured to encrypt SNMP messages using a FIPS 140-2 approved algorithm, this is a finding.
