your config are ok. can you try to ping from any ip address in range of inside address.

please do not forget to rate.

I cant reach the inside address , I think is a problem of ARP , maybe I have to clear ARP in some switches .

What do you think?

clear arp best is do in change control all arp cache entries will flush. could be  a downtime for a 2 to 3 secounds

please do not forget to rate.

Hi,
Is your vlan 602 IP address is from the same range of 192.54.119.128/26, your ASA & Switch side configuration is OK.
Please verify one more PO5 is connected ASA1` & PO 15 is connected to ASA2.

Hope This Helps

Yep, the vlan 602 is assigned to that range 10.54.119.128/26  . Po5 to FW1 and Po15 to Fw2 , I will try again but how this is a production enviroment  I wanted to make sure that the config is Okey
