default auto negotiate shows a-full a-100?

[MikeNY85]

Hi,

I was doing a test for speed and duplex on configured interfaces of two switches. I issued the command "show interface status", the output showed "connected" status with auto     auto  in packet tracer. I didn't hardcode any side (speed and duplex are in default). I am assuming it should show a-full (for full duplex) and a-100 (for a speed of a FastEthernet link (100 Mbps) if both sides negotiate speed and duplex by default. I just want to understand which option should show up?

the result depend on both side not only on one side 
check table above

These are two switches. The interfaces on both sides are set to auto negotiation (default). Isn't the output should be a-full and a-100 (fastethernet) if both sides are on auto negotiation (default)?. Or this is just a glitch in packet tracer?.

set to auto, 
some interface like SFP multi G not support auto so you need to hardcode the speed and duplex.

Thanks for your answer and I really appreciate it!. I am using "packet tracer" and the output (auto    auto) came on packet tracer. Generally speaking, isn't the output should be a-full  a-100 (full duplex and fastethernet speed). (assuming we are on default settings)?

OK
so you use PKT, 
then do 
show interface f0/1
you will see the right duplex and speed. 

I think it some PKT limitation that not show the status correctly.

Thanks again and much appreciated!. So, in real world and without any complications, for an active interface with auto-negotiation (default settings) (full duplex and Fastethernet), If I issued the command "show interface status" I should see the output a-full and a-100 for the active interface with auto-negotiation of speed and duplex? Yes or No?

thanks in advance!

Yes sure you will see it. 
auto/auto will give as you mention before a-full & a-100

Duplex not conflict

One side is auto negotiation
One side is no negotiation
It is in full duplex status.

WLC#sh run int t0/1/1
interface TenGigabitEthernet0/1/1
 switchport mode trunk
 speed 1000
 no negotiation auto
 no snmp trap link-status
 channel-group 1 mode on
end
!
Switch#sh run int g1/0/2
interface GigabitEthernet1/0/2
 switchport mode trunk
 channel-group 1 mode on
end
!
WLC#sh int t0/1/1
