Bug ID 2354021: An LTM policy configured to only disable AVR (avr disable) cannot be applied to a virtual server unless an AVR (analytics) profile is attached.

Opened: Jun 25, 2026

Severity: 3-Major

Symptoms

When attaching an LTM policy containing an avr disable action to a virtual server without an AVR (analytics) profile, the configuration is rejected, and MCP logs a validation error similar to: 01071809:3: Virtual server /<partition>/<vs_name> requires a profile of type avr for ltm policy /Common/<policy_name>. The policy applies successfully only if an AVR profile is manually attached to the virtual server.

Impact

The configuration is rejected and cannot be committed. Because the AVR control requirement is keyed on the action target rather than on whether the action enables or disables AVR, MCP requires an AVR profile even when the policy only disables AVR. As a result, you cannot use an avr disable action to suppress AVR statistics collection on a virtual server unless you also attach an AVR profile that you may not otherwise need. There is no configuration-only workaround other than attaching an AVR profile to the virtual server.

Conditions

- An LTM policy contains a rule with an avr action, and that action is set to disable (no avr enable action is present in the policy). - The policy is attached (or being attached) to a virtual server that does not have an AVR (analytics) profile. - This commonly arises when an LTM policy is used to disable AVR statistics collection for specific connections on a virtual server that has a DOS (DoSL7) profile but no AVR profile. The DOS profile causes AVR to run implicitly, and avr disable is the action used to stop AVR statistics collection for those connections.

Workaround

Attach an AVR (analytics) profile to the affected virtual server. With an AVR profile present, the avr disable action validates successfully and takes effect.
