ZTNA scalability support for up to 50 thousand concurrent endpoints

ZTNA scalability is increased to support up to 50 thousand concurrent endpoints. Communication between FortiOS and FortiClient EMS is improved with more efficient queries that request incremental updates. Retrieved device information can be written to the FortiClient NAC daemon cache.

FortiOS can receive tag information from the EMS common tags API. This feature requires FortiClient EMS 7.0.3 or later.

The APIs api/v1/report/fct/uid_tags and api/v1/report/fct/tags replace the API api/v1/report/fct/host_tags.

To use the common tags API capability:
  1. Enable the common tags API when connecting the EMS:

    config endpoint-control fctems
        edit "local.ems"
            set server "10.6.30.213"
            set capabilities fabric-auth silent-approval websocket websocket-malware push-ca-certs common-tags-api
        next
    end
  2. The FortiGate uses the new APIs to obtain device information from the EMS:

  3. Confirm that the device information from the EMS is written to the FortiClient NAC daemon cache:

    # diagnose endpoint record list
        ...
              Avatar source: OS
                Phone number:
                Number of Routes: (1)
                        Gateway Route #0:
                                - IP:10.1.91.6, MAC: 4f:8d:c2:73:dd:fe, Indirect: no
                                - Interface:port2, VFID:1, SN: FG5H1E5999999999
    online records: 37174; offline records: 0; quarantined records: 0; out-of-sync records: 0
  4. Use the tags that are pulled from the EMS in a firewall address:

    config firewall address
        edit "FCTEMS8888888888_ZT_AD_MGMT"
            set type dynamic
            set sub-type ems-tag
            set obj-tag "ZT_AD_MGMT"
            set tag-type "zero_trust"
        next
    end
  5. Check the tags' resolved IP and MAC addresses:

    # diagnose firewall fqdn getinfo-ip FCTEMS8888888888_ZT_AD_MGMT
    getinfo FCTEMS8888888888_ZT_AD_MGMT id:114 generation:106 count:187 data_len:6160 flag 0
