We have this two equipments (show above) connected in this manner
3560 (fa0/4) <---> (Gi0/2) 2960
1) When we power up the 2960 with the UTP Cable connected, the uplink will not go up, we need to replug the cable then the link will come up.
2) The rebooting the 3560 even unpluggin the UTP does not resolve the problem.
Theres no log indicating why the interface was down
Please help... Thank you
Solved! Go to Solution.

Hi,
There might be a negotiation mismatch happening between the switches as one switch is having a fast ethernet port whereas the other switch is having a gigabit ethernet port.
You can try putting both the ports forcefully to 100 Mbps full duplex and then can verify their behaviour.
The commands for the above are:
3560 switch:
conf t
interface fa0/4
speed 100
duplex full
2960 switch:
conf t
interface Gi0/2
speed 100
duplex full

Pls rate.

Could you please paste the interface config for both the ports.
What happens when you reboot the 3560. Do you see the same behaviour on 2960 or 3560 side.

3560
!
interface FastEthernet0/4
switchport trunk encapsulation dot1q
switchport mode trunk
!
2960
!
interface GigabitEthernet0/2
switchport mode trunk
!
its on the 2960 side only, there are 2 3560, the interconnect are working fine on 3560 when powered up

Man meet,
We will try this sunday.

rqsantos, would like to know whether this is a new setup or this connectivity was working properly earlier.
Thanks EM

When the link does not come up see sh int fa0/4 and sh int gi0/2 on the switches and see what is the speed and duplex shown in the output.
As suggested above force the links to 100 / Full.

Hi Tee,
Were not able to investigate this anymore. It worked when we force to 100/full
Thank you
