Amber light - ASA Interface

I have two ASA5540's in HA an Active/Standby mode. When I first started configuring the firewalls I had them connected to a Cat2950. The lights on the interfaces were Green/Green. Yesterday we moved them to there final resting place, I have them connecting to a Cat6k. Now the interfaces are showing Green/Amber. Why?? When I do a "show int" I see no errors on the ASA or Cat6k. I am also using the same cables I was using when I had the ASA connected to the Cat2950, so I know the cables are good.

Re: Amber light - ASA Interface

Could you please provide the output of "show int" command?

Re: Amber light - ASA Interface

the amber light suggest the different speed and duplex settings on the " firewall and cat's interface ".

please make sure that they have same speed and duplex settings.you can configure the speed and duplex manually on the firewall and cat6 or you can simply select " auto " for auto negotiation.

seems to be bad cable.

As you can see I have set each side set to be 1000/Full. What really confuses me is I do not have this issue when connecting to a low end swith like a Cat2950 but I do when I connect to a high end swith like the Cat6k. I get the amber light no matter how I configure the ports.

Re: Amber light - ASA Interface

TAC have thoroughly tested this issue and we have the following result:

in 7.2 versions the active led is no longer showing the activity of the

device but it's current failover state, meaning the current active

device's LED is green and the standby's LED will be amber. So it

isn't showing any problems.

is the active Devices's LED as amber ?

Re: Amber light - ASA Interface

Yes both ASA's SFP Link LED are amber. I say that because the link you sent me identifies that status light as the SFP Link LED. The switch I am connecting too for failover only supports 100/Full and my inside / outside are running at 1000/Full. Could that be the reason?

I should also point out I have seen this exact issue at two other sites. And at both sites I am connecting to a Cat6k, just like I am here.

Re: Amber light - ASA Interface

yup...i think this is the problem.please set firewall on 100mbps/full duplex and that should resolve this.

Re: Amber light - ASA Interface

at 1000 Mbps you would see Amber light...you change it to 100 Mbps and it will turn green

Is the colour of light only the issue bothering you ?

What problems are you experiencing other than the colour thing..and this would help us to narrow down the issue

Re: Amber light - ASA Interface

Ahh, ok. That makes sense. I was told by Cisco TAC that the amber light meant I had an issue with a cable or something. I am experiencing no issues. I didn't realize the amber light meant I was connected at 1000 mbps. Thank you for this answer.

Amber light - ASA Interface

have the same problem too,

we have 2 ASA 5540 (Active/Standby) and one catalyst 3750 that the ASAs connected to it, in the normal situation everything is good, but when the Active ASA fails and the secondary become Active the switchport that connected to Secondary ASA become Amber/Green and the and the speed going to slow with 30% packet lost,

I also checked the connectivity and change the switchport but no success.

appreciate any help

Amber light - ASA Interface

Hi Arash,

You might need to check the duplex and speed setting as well, between the secondary ASA and the switch it is connected to.
