I maybe have a stupid question, but I did not find any useful way for my problem.
My customer ist using 3850 access switches. He want to enable monitor mode in first phase to do the inventory of all connected endpoints. Second phase he wants to move to low impact mode. However, I simply started with IBNS 1.0 open mode, which worked fine so far. Then I used one switch and upgraded tp 3.6.4 and changed to "new style". Unfortunatly the monitor configuration seams not to be converted.
This is my initial configuration:
interface GigabitEthernet1/0/13
...
switchport access vlan 10
switchport mode access
switchport voice vlan 20
ip access-group ACL-ALLOW in
authentication event fail action next-method
authentication event server dead action authorize vlan 10
authentication event server dead action authorize voice
authentication host-mode multi-auth
authentication open
authentication order dot1x mab
authentication priority dot1x mab
authentication port-control auto
authentication periodic
authentication timer reauthenticate server
mab
no snmp trap link-status
dot1x pae authenticator
dot1x timeout tx-period 10
no cdp enable
spanning-tree portfast
After the convertion I had the following config:
service-template CRITICAL_AUTH_VLAN_105
vlan 105
policy-map type control subscriber DEFAULT_POLICY
event session-started match-all
10 class always do-until-failure
10 authenticate using dot1x retries 2 retry-time 0 priority 10
event authentication-failure match-first
5 class DOT1X_FAILED do-until-failure
10 terminate dot1x
20 authenticate using mab priority 20
10 class AAA_SVR_DOWN_UNAUTHD_HOST do-until-failure
10 activate service-template CRITICAL_AUTH_VLAN_10
20 activate service-template DEFAULT_CRITICAL_VOICE_TEMPLATE
30 authorize
40 pause reauthentication
20 class AAA_SVR_DOWN_AUTHD_HOST do-until-failure
10 pause reauthentication
20 authorize
30 class DOT1X_NO_RESP do-until-failure
10 terminate dot1x
20 authenticate using mab priority 20
40 class MAB_FAILED do-until-failure
10 terminate mab
20 authentication-restart 60
60 class always do-until-failure
10 terminate dot1x
20 terminate mab
30 authentication-restart 60
event agent-found match-all
10 class always do-until-failure
10 terminate mab
20 authenticate using dot1x retries 2 retry-time 0 priority 10
event authentication-success match-all
10 class always do-until-failure
10 activate service-template DEFAULT_LINKSEC_POLICY_SHOULD_SECURE
interface GigabitEthernet1/0/13
service-policy type control subscriber DEFAULT_POLICY
Is it true, that the "authentication open" command does not get converted?
Or is the monitor mode simply not supported with IBNS 2.0? Even when I trie to add the commands to the "old style" interface again, it did not work at all. Any hints are highly welcome.
Thanks, Marco

Marco, with IBNS 2.0, the open mode is the default whereas with IBNS 1.0, closed mode was the default setting. So what you are seeing is expected. Even though you are not seeing the command, the interface will operate in open mode. You can run 'show run all' to see the command.
IBNS 2.0:
Open mode (Default): no access-session closed
Closed mode: access-session closed
IBNS 1.0
Open mode: authentication open
Closed mode (Default): no authentication open

Hi Hosuk
Thanks for this clarification. In this case I have to check the software Version. Since even when I go back to old-style, the switch did not work as expected (to be honest I not checked before change to "new style"!)
Do you have any experience with 3850 IOS XE 3.6.4?
Next week I will check another IOS Version, maybe 3.7.3 or any other suggestion?
Thanks, Marco

Marco,
Currently, we recommend IOS-XE 3.6.3 with 3.6.4 most likely to be the new recommended version once ISE 2.1 is available. I'm pretty sure 3.7.3 would work as well since it contains a lot of identity related fixes that are in 3.6.3 and 3.6.4.
