# Create certificate attribute group mygroup1 and add two attribute rules. The first rule defines
that the DN of the subject name includes the string aabbcc, and the second rule defines that the IP
address of the certificate issuer is 10.0.0.1.
[Device] pki certificate attribute-group mygroup1
[Device-pki-cert-attribute-group-mygroup1] attribute 1 subject-name dn ctn aabbcc
[Device-pki-cert-attribute-group-mygroup1] attribute 2 issuer-name ip equ 10.0.0.1

# Create certificate attribute group mygroup2 and add two attribute rules. The first rule defines
that the FQDN of the alternative subject name does not include the string of apple, and the second
rule defines that the DN of the certificate issuer name includes the string aabbcc.
[Device] pki certificate attribute-group mygroup2

[Device-pki-cert-attribute-group-mygroup2] quit
3. Create a certificate attribute access control policy named myacp and add two access control rules.
[Device] pki certificate access-control-policy myacp
[Device-pki-cert-acp-myacp] rule 1 deny mygroup1
[Device-pki-cert-acp-myacp] rule 2 permit mygroup2
[Device-pki-cert-acp-myacp] quit
4. Apply the SSL server policy and certificate attribute access control policy to HTTPS service and
enable HTTPS service:
# Apply SSL server policy myssl to HTTPS service.
[Device] ip https ssl-server-policy myssl
# Apply the certificate attribute access control policy of myacp to HTTPS service.
[Device] ip https certificate access-control-policy myacp
# Enable HTTPS service.
[Device] ip https enable
