Description:
Bug ID 901569: Loopback traffic might get dropped when VLAN filter is enabled for a virtual server. ... Last Modified: May 08, 2024 ... Symptoms ... Loopback traffic (local traffic) destined to a virtual server might get dropped when the incoming packet matches a terminating connection flow. ... Impact ... Traffic that is matched against a terminating connection flow of a virtual is not processed by the virtual server. ... Conditions ... -- VLAN filter is enabled on the virtual server created for loopback traffic processing. -- An incoming packet matches a terminating connection flow (i.e., the connection flow terminates because of timeout, being dropped by iRule, etc.). ... Workaround ... Because this filter is ignored for loopback traffic, removing the 'Enabled On VLAN' filter at the virtual server mitigates the issue. ... Fix Information
