We have 10G fiber running since 1 year but today I have migrate that same link to ASR1006 and I am seeing following error, what could be the problem?

Oct  7 17:29:48.211: %IOSXE_SPA-6-UPDOWN: Interface TenGigabitEthernet1/1/0, link down due to remote fault
Oct  7 17:29:48.424: %IOSXE_SPA-6-UPDOWN: Interface TenGigabitEthernet1/1/0, link down due to local fault

SPA status looks good

#show hw-module subslot all oir
Module        Model                Operational Status
------------- -------------------- ------------------------
subslot 0/0   SPA-1X10GE-L-V2      ok
subslot 0/3   SPA-1X10GE-L-V2      ok
subslot 1/0   SPA-1X10GE-L-V2      ok
subslot 1/1   SPA-1X10GE-L-V2      ok

UPDATE

This is very interesting, same fiber I moved back to C3850 switch and it works! but if I moved back to ASR1006 it didn't work.

But if I connect ASR1006 same fiber port to C3850 back to back (1 meter distance) and assign random IP to test ping and it work!

SPF model is Cisco XFP-10GLR-OC192SR

What could be the issue?

  • I have opened cisco TAC to see, they are saying move port to other SPA to check. i will let you know once i do that

  • Did you ever hear back from Cisco TAC regarding this?

  • Yes it was faulty SIP/SPA module, they replace hardware.
