Parameters

Name Meaning

OID

Indicates the ID of a MIB object.

Parameter

Indicates the CAPWAP security parameters.

undo capwap dtls no-auth enable: The function of establishing CAPWAP DTLS sessions in none authentication mode is disabled.

capwap dtls cert-mandatory-match disable: The function of establishing CAPWAP DTLS sessions through the preset certificate is disabled.

Impact on the System

If the function of establishing CAPWAP DTLS sessions in none authentication mode is enabled (using the capwap dtls no-auth enable command), new APs are allowed to set up CAPWAP links with the AC, which poses security risks.

If the function of establishing CAPWAP DTLS sessions through the preset certificate is enabled (using the undo capwap dtls cert-mandatory-match disable command), new APs can use the preset certificate for DTLS authentication and then set up CAPWAP links with the AC, which poses security risks.

Possible Causes

In CAPWAP DTLS authentication scenarios, the function of establishing CAPWAP DTLS sessions in none authentication mode or through the preset certificate may be enabled during AP deployment or capacity expansion. If the enabled function is not disabled after 1 hour, this alarm is triggered.

Procedure

  1. Run the undo capwap dtls no-auth enable or capwap dtls cert-mandatory-match disable command in the system view to configure the CAPWAP security parameters.

    • If the alarm is cleared, go to Step 3.
    • If the alarm persists, go to Step 2.

  2. Collect alarm messages, log messages, and configurations, and then contact technical support personnel.
  3. End.
