[Mirzo]

Dear all 

I have issue between vlans. I created  8 vlans by port-channel In Cisco  ASA 5525. I tried ping between two vlans but ping showed us "time out". Could you suggestion how to configure my asa than between two vlans is working .

Sorry  my bad english

Hi
By default the ASA will block pings, you can use a inspect icmp global policy to allow pings through between different networks

Try with below command

policy-map global_policy
   class inspection_default
   inspect icmp

if you are using ASDM, go to service policy menu and edit global service policy to enable ICMP inspection

I done this steps. but it does not help me

class-map inspection_default

My PC ip is 172.18.2.25 I tried to ping GW 172.18.2.254 ping going on successfully. than i try to ping other GW 172.18.3.254 whom installed other vlans my ping is showed time out. i did't reach other vlans

It may be worth removing the ACLs and letting the security zones do there thing, failing that check the hit count on the ACL and or run a packet capture and show all denied traffic, something like
packet capture NAME type asp real-time drop type all
This should help see what is going on
