Hi all, Strange problem i have a ASR1001-X with GLC-LH-SMD not coming up, the GLC-LH-SMD are seen by the ASR but the link stays down
but with GLC-SX-MM's installed the link comes up and is fine
i have tested the LH's in other devices and they are fine anyone had this problem?

about the only thing that I can think of would be, on the ASR interface, try
no negotiation auto
if you haven't already, and see what happens.
I don't have a lot of instances to compare to, but on each of my ASR1ks, that have a fiber SFP, they are all set to no negotiate auto. I wouldn't necessarily think that would matter but maybe there is some nuance with optical vs RJ SFPs.
06-22-2020 08:08 AM
1. is that port not come up or going to error disabled mode.
2. are you using Single mode cable or multimode ?
3. what is remove end SFP ?
try adjusting speeds or no speed nogiations ? is this usefull ?
Also worth looking for your version there is bug reported :

when you say multimode cable, do you mean just a jumper to another device, or do you mean multimode to an LIU (IE-fiber up a riser, or to a different location/building)?
as far as I recall, with the LH optics, using multimode fiber, you would need a modal conditioning jumper. I believe that is noted in the SFP spec sheet. Or, at least it used to be.
06-22-2020 10:00 AM
It's just a jumper cable, but the LH's and the same cable work when I connected to switches together which makes me think I'm missing something
06-22-2020 10:17 AM
ok, fair enough. what does your interface configs look like, on both sides? seems more of a link layer problem than physical layer

Can you post below output from both the devices.

This is what i have suggested other post the check the negotiation and speed, any way coming back to post down at Switch side.
it is Layer 2 port ( make it either Layer 3 port)
for testing
interface GigabitEthernet2/1/1
shut
no switchport
ip address 192.168.1.101 255.255.255.0
no shut
lets us know how it goes.
