Description:
Bug ID 1572545: Upgrade from version 14.X to version 15.X may encounter problems with L2 forwarding for some of the flows. ... L2 forwarding issues may be encountered for some flows. ... Due to this, there can be hinderances in the traffic flow towards server. ... Impact ... Traffic drop is observed when packets are sent towards server. ... Client and server are in same vlan but not in same subnet. ... 2. Gateway is in another vlan, it is the gateway for both client and server. ... Client traffic over transparent vlan-group towards Server is intercepted by a standard virtual server and sent to IPS on a non-vlan-group vlan. ... 2. connection.vgl2transparent is enabled 3. ... When traffic is sent from BIG-IP to IPS, the destination MAC will be the MAC address of a server (ARL non local) and the source MAC is still the original client MAC which is breaking the returning traffic from IPS. ... 4. The expectation here is traffic leaving from BIG-IP to IPS should have BIG-IP nonVgVlan1 MAC...
