MPLS Tunnel is down

MY company use mpls tunnel between site offices and HO, one switch (Cisco CAT 3560 8 port ) in our site office connected to the service provider mpls device (it use IP/MPLS microwave solutions) to connect HO through Service Provider MPLS network.

the issue is the switch (Cat 3560) port LED connect with MPLS device blinking green and amber, the tunnel is also down.

so what might be the cause for this issue?

it seems the power issue on ip/MPLS microwave devise...
is the microwave device getting power from this switch ?

Alternating green and amber : PoE is denied because providing power to the powered device will exceed the 370 W switch power capacity.

1. duplex and speed are match between the devices
2. No the MPLS microwave device not getting power from the switch, MPLS microwave device has its own power source.

but the problem still exists....

Yes, MPLS device is working fine. (both the MPLS Device and Cat 3560 switch are configured by ISP)

[max_the_king] you were right I have asked ISP and they found the duplex and speed mismatch and they fixed,
