seems to be still an issue. we are running into the same problem with Apple iOS devices: https://community.cisco.com/t5/identity-services-engine-ise/ise-2-4-patch-6-ios-12-2-onboarding-issues/m-p/3830842 Patrick

It seems that ISE is rejecting the MAB authentication for the IP phone.
What does your ISE Operations Log say?

We just ran into the same issue with VM based on SNS-3415 and contacted TAC.
I am wondering why Cisco did not include this hotfix in the patch bundles; the bug tool says there has been 117 TAC cases related to this issue.

Thanks Bogdan, I just tried it and it works like a charm!
The FMC doc under ECMP routing says it is not supported across different interfaces.
https://www.cisco.com/c/en/us/td/docs/security/firepower/620/configuration/guide/fpmc-config-guide-v62/routing_overview_for_firepower_threat_defense.html#ID-2101-0000004d
It is the same text as ASA doc before the zone feature was introduced, they just forgot to correct it. They should have a reference to the FlexConfig zone name ecmp.

ASA 9.3(2) introduced the concept of zones with ECMP support across different interfaces (in the same zone):
You can group interfaces together into a traffic zone to accomplish traffic load balancing (using Equal Cost Multi-Path (ECMP) routing), route redundancy, and asymmetric routing across multiple interfaces.
Any idea when FTD will support this? the interface zone in FMC seems to be for Snort, not for ASA Lina, only nameif is present in Lina CLI:
firepower# show nameif Interface Name Security Ethernet1/5 inside1 0 Ethernet1/6 inside2 0
firepower# show zone firepower#
EIGRP neighbors come up on both interfaces but routes are only present on inside1.
Is there a recommended design for FTD using L3 routing to 2 Nexus switches? I can't have EIGRP neighbors on vPC VLANs... so I opted for L3 routed interfaces between the 2 Nexus and between each Nexus and FTD.
Thanks

Yeah I saw that bug.
I just found a workaround. Since I am using a private (internal) certificate for ISE admin and EAP, it has to be trusted in the MAC trust store manually before continuing the BYOD onboarding process, same behavior as iOS 10.3+ documented in bug CSCvd38467
Cisco recommends using public certificates for BYOD, now I know why!

Thanks Francesco, we are looking into patching but it doesn't seem like a known issue listed on bug toolkit or in the release notes.
I am wondering if it is caused by the ISE admin and EAP certificates being generated by an internal CA instead of public. I know iOS 10.3.+ does not like that and requires an extra step to trust the certificate manually during onboarding, maybe MAC OS is even stricter now.

I am running into an issue with ISE 2.2 patch 4 running the latest SPW for MAC OS X with the latest HighSierra update 10.13.2. BYOD flow does not work, it fails inside the Cisco Network Setup Assistant at the early step of downloading profiles. It shows 2 popups for ISE certificate to be trusted then fails to actually import them into the certificate store.
anybody experiencing the same issue?

From memory UDP source and destination are both 500. But then what about NAT-Traversal...
Looked up the RFC :
https://tools.ietf.org/html/rfc3947#section-3
The detection of support for NAT-Traversal and detection of NAT along
the path between the two IKE peers occurs in IKE [RFC2409] Phase 1.
The NAT may change the IKE UDP source port, and recipients MUST be
able to process IKE packets whose source port is different from 500.
Do you support nat-t on your ASA? Enabled by default as of 8.0(2)
crypto isakmp nat-traversal
Hope that helps! Patrick

RSPAN is layer 2 (so you have to transport the L2 VLAN over L3 MPLS).
Have you looked at ERSPAN which uses GRE encapsulation?
I have used ERSPAN to AlienVault VM since I was not able to RSPAN at layer 2 to UCS...
We ran into an issue at some point when AlienVault moved from Snort to Suricata but the support fixed it.

Yes, ASA runs its own inspect and sends a copy of the packets to the Firepower module.
Firepower runs preprocessor and other advanced security (IPS, AMP...) on the connections and instructs the ASA to drop or reset a connection if needed.
Hope that helps.

Thanks a lot for the information. I upgraded 2.1 patch 3 to patch 5 (to fix a backup bug) then took a backup and ran the upgrade to 2.2 18 hours later, I cannot SSH into the VM or access the GUI. I actually get a login prompt via SSH and get the banner then nothing happens when I enter the password, the prompt just freezes: login as: admin BANNER... admin@10.23.83.157's password: Maybe the best strategy is a fresh 2.2 and restore Patrick
