Hi all,

 

Just for your info. We recently disabled MAC-Masquerading and went back to default GARP.

 

No ping losses anymore => problem solved! ;-) So I assume that there is an Issue with VSS Cisco and Cisco's CEF Feature when using F5 MAC-Masquerading. The VSS-Cluster has an uptime of over 3 years...;-) Looks like a VSS Bug. The network team will analyze the issue in more detail.

 

Thanks a gain for your answers Regards thrillseeker
