Unable to ping gateway from ASA instance

[malhotra_suneet]

HI have a ASA instance on a Firepower 4420 device.

I have defined Eth1/1 as the management interface with ip address 10.80.80.5 255.255.255.0 and default gateway as 10.80.80.1 

config

!
interface Ethernet1/1
management-only
nameif management
security-level 0
ip address 10.80.80.5 255.255.255.0
!

route management 0.0.0.0 0.0.0.0 10.80.80.1 1

========================================

Now I connect a PC with IP Address 10.80.80.1 /24 and unable to ping both ways, 

I can see amber light on the port LED on firepower, 

although the interface status is up 

asa# show int ethernet 1/1

Any lead will be great.

If I remove the cable I still see ASA eth1/1 as up up and that is because it is a logical instance of ASA on physical Firepower box, and interface mapping is being done. The problem still remains,

[malhotra_suneet]

dug a little bit and found that the fxos is showing interface eth1/1 as down, not sure why


Firepower-4120-Lab-A(fxos)# show interface
Ethernet1/1 is down (Link not connected)
Dedicated Interface
Hardware: 1000/10000 Ethernet, address: 00fd.2270.b65c (bia 00fd.2270.b65c)
Description: U: Uplink

in that case, we need to more information, how is your Cabling connected to switch?

post switch config and tell us what port it was connected 

is this port-channel connected Firepower chassis to switch?

[balaji.bandi]

have you configured below lines  to permit ICMP,

if not add them and try

icmp unreachable rate-limit 1 burst-size 1
icmp permit any management

if you required inside interface ping add below line

icmp permit any inside

test and advise.
