ANC Endpoint API gives a HTTP 404

Konrad Reszka — Fri, 23 Mar 2018 20:39:38 GMT

I'm trying to apply an ANC policy using the ERS API URI of "/ers/config/ancendpoint/apply" but ISE only returns an HTTP 404 error. Other ERS API calls work wonderfully so it's not header or authorization problem.

ISE is on 2.3

Please turn DEBUG on ers and watch ise-psc.log, which should give you some clues what's missing.

If not, please post a complete request sample.

Below works for me:

curl -X PUT -k -H 'Content-Type:  application/json' -H 'Accept:  application/json' -i 'https://myAdminUser:myPassword@myISE:9060/ers/config/ancendpoint/apply' --data '{
"OperationAdditionalData" : {
    "additionalData" : [ 
    { "name" : "macAddress", "value" : "02:00:00:00:00:01" }, 
    { "name" : "policyName", "value" : "testANC-Q01"}
   ]
  }
}'

Specifically, ISE is on version 2.3.0.298

It looks like the URI PATH is not being parsed, it's showing as null. Here's a snippet:

I am unable to reproduce your errors in my setups of ISE 2.3 Patch 2 and ISE 2.3 FCS so it seems something odd in yours. I am guessing either the ISE services not properly initialized or the like.

If the setup does not have 16-GB RAM or more, please try allocating more memory.

Hey Konrad,

Unicast me in what you are trying to accomplish, is it simply applying the endpoint to the ANC policy and the failure occurs, i see a custom page error message.

Thanks,

John

This is due to CSRF validation. Please read the section on this in ISE 2.3 Release Notes, API Documentation from the ERS Online SDK.
