Hello Everyone!
We have a parking lot switch wich is WS-C3850-48P and uplink port goes through GigaBeam LR-Ubiquity link back to the distrbution switch, I checked everything on the ubiquity link including alignment and power, including port duplex but still the Link goes up and down. you can take a look at the topology I attached to understand more of the setup.
on the distrbution side we have C6880-X-LE port TenGigabitEthernet1/1/16 with 1GB copper SFP and here is the output of the interface:
TenGigabitEthernet1/2/16 is up, line protocol is up (connected)

on the remote side we have Catalyst 3850-48 Port and connected to GigabitEthernet1/0/1 and here is the output:

Here is the config on both side as well :
interface GigabitEthernet1/0/1
description cds01_te1/2/16
switchport trunk native vlan 888
switchport trunk allowed vlan 124,224,400,803,923
switchport mode trunk
switchport nonegotiate
spanning-tree portfast disable
ip dhcp snooping trust
end
interface TenGigabitEthernet1/2/16
description prklt-Gi1/0/1
switchport
switchport trunk native vlan 888
switchport mode trunk
switchport trunk allowed vlan 124,224,400,803,923
switchport nonegotiate
logging event link-status
end
any idea why I have input errors and CRC ? I changed SFP , Cables and ports but still no luck. appreciate anyone comment and solution
