Cannot Ping ASA IP Addresses

[Net_Stef]

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 10.10.1.0/24 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 10.10.2.2 (SW IP VLAN 2), but i cannot ping 10.10.2.1 (ASA IP VLAN 2).

In fact, i cannot ping any other FW IP except the one from Interface VLAN 1 (10.10.1.10).

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,

Stef

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

and

show interface ethernet0/1

you said you can ping when your PC is VLAN 1 (10.10.1.10) 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
