Hi All,
Need your support for the below case, while doing new connectivity on CISCO ASR920 I observed an abnormal behavior like
1- New fiber cable connected to one port and physically it is showing up and green but when i login to the router i found the interface status still showing down... SFP changed still no change
2- Another port was up and green but no traffic on that port so we removed the cable and SFP then we checked the interface status still showing up.. we shut and no shut the interface then the interface status changed to Down
3- We did a direct loop on the interface but the interface status still showing down
as per the above deferent scenario we want to figure out the root cause for the abnormal behavior. this is due to [ hanging issue, software upgrade or license issue...]
below is the router information
