Hi,

I suppose you are unable to ping VIP.

Please configure command " loadbalance vip icmp-reply" or loadbalance vip icmp-reply active".

You should be able to ping VIP after configurig the first command no matter whether servers are active or not. If you configure second one then only if servers in serverfarm are operational you will get the response.

Let me know if that works out for you.

Regards,

Kanwal

i try to ping Vlan 64  to Vlan 55 but no ping

Hi Faisal,

This is actually expected.  Check this;

'For security reasons, the ACE does not allow pings  from an interface on a VLAN on one side of the ACE through the ACE to  an interface on a different VLAN on the other side of the ACE. For  example, a host can ping the ACE address that is on the IP subnet using  the same VLAN as the host, but cannot ping IP addresses configured on  other VLANs on the ACE. "
