Cannot Ping ASA IP Addresses


Hello all,


I have the following Network Setup:

ASA 5505(Security Plus License) -->Cisco Switch WS-C2960-8TC-L -->PC


ASA has 8 interface VLANs, each one with an IP assigned. Cisco Switch has also 8 VLANS each one with an IP assigned.

My PC belongs to network, and PC interface on SW is mode access VLAN 1. Link of ASA to Switch is trunk on both sides, allowing all VLANs.


I can successfully ping (SW IP VLAN 2), but i cannot ping (ASA IP VLAN 2).

In fact, i cannot ping any other FW IP except the one from Interface VLAN 1 (


All FW interfaces have the same security level (100), i have enabled same-security-traffic permit inter-interface, same-security-traffic permit intra-interface, inspect icmp and icmp permit any USERS (VLAN 2).


Could you please assist in order to resolve the issue? I have also attached the configuration from ASA and Switch.


Thank you,

looking into your config. your switch interface FastEthernet 0/8 trunk connected to ASA Ethernet0/1. your config looks ok can you make sure the cables are connected properly.

can you share share the output of the command


show interface fastethernet 08


show interface ethernet0/1

you said you can ping when your PC is VLAN 1 ( to the default gateway of the ASA.
if that correct than you have to understand you can not ping from PC in VLAN1 and you want to
ping to VLAN-X on ASA interface X. this is by default.

if you try to ping the default gateway of ASA in its respective ip address range it will ping back/reply the pings
