Dear Network Admins,
I have a problem about uplink port that is connected between cisco 3850 and mpls panel. I used GLC-LH-SMD sfp by doing this but releated uplink port notconnect.
let me say interesting thing, normally HP switch is connected to mpls like cisco 3850, it is working fine, i mean used HP SM sfp for HP switch uplink port and it is working fine. Then i connected it on cisco 3850s by ame sm cable that is coming from mpls panel, it seems noconnected, also changed sfp cisco glc-lh-smd by doing this. Below is configuration; please help me..
CÄ°SCO 3850;
Gi1/0/12 notconnect 1 full 1000 1000BaseLX SFP
interface GigabitEthernet1/0/12
switchport trunk allowed vlan 500
switchport mode trunk

Kindly check the logs of the switch if the port(s) are in error-disable or not (CSCvg95411)?

Hello,
is the SFP actually recognized by the switch (show version) ? You need XE 3.3.3SE or Denali 16.1.1 for the 3850 to recognize the SFP...
