LACP marker protocol issue:

If the EVO device receives an LACP marker request; the EVO device does not ack back with a LACP Marker response.

 In the packet capture you will not see an LACP marker response.

• Attached screenshot from a packet capture of the EVO device.
• File 1: Request_Marker_JunosDevice_NonEVO.jpg --> shows request marker on a non evo device.
• File 2: Response_Marker_JunosDevice_NonEVO.jpg --> shows response marker on a non evo device.
• File 3: EVO-Device-Capture-after-fix.pcap --> capture on an EVO device after fixing the issue; shows both request and response for Marker protocol.
