Dears,
As per the link below ISR 4331 supports GLC-SX-MMD i have inserted in gig0/0/2 and the media type seen on the interface is unknown the same sfp works fine in gig0/0/0 interface. i have checked the same SFP on another new router and status is same,
any hints is there any license issue to activate 3 interface
sh int gig0/0/2
GigabitEthernet0/0/2 is down, line protocol is down
Hardware is ISR4331-3x1GE, address is 009a.d286.1f82 (bia 009a.d286.1f82)
MTU 1500 bytes, BW 1000000 Kbit/sec, DLY 10 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive not supported
Full Duplex, 1000Mbps, link type is auto, media type is unknown media type
output flow-control is on, input flow-control is on
CPE01(config)#int gig0/0/0
CPE01(config-if)#media-type ?
auto-select Use whichever connector is attached
rj45 Use RJ45 connector
sfp Use SFP connector

mmm yes, it is not a normal behavior, this link shows a similar situation:

I will search more information.

Hi,
Port 0/0/0 can be configured as SFP or RJ45
Port 0/0/2 is SFP only and that is why you don't see the media type command available.
So, LC-SX-MMD should work in 0/0/2.
As far as I know, there is no license restrictions. You can use all on-board ports.

try no negotiation auto under the interface

i have just inserted a SFP to check whether it is supporting or not, and i got trap in this issue. i didn't connect any device to this port.
thanks

I upgraded the IOS today but no luck.
thanks

Hi
It is not a normal situation, if you have Cisco contract try to open a ticket with the Cisco TAC, it could be a hardware problem.

Dear Julio,
i have 2 no's of ISR 4331, in both ISR same problem, the same SFP works fines in gig0/0/0 but it shows unknown in gig0/0/2
very strange , i think i m missing some interface command for the ISR 4331 routers to activate the sfp on gig0/0/2
thanks

Dear Julio,
i saw the link and i tried by degrading to 3.15 but no success i dont know how to solve this issue.
thanks

Hi
I think I found the problem, this is my interpretation but, apparently the G0/0/2 is a dedicated port for Ethernet, in few words just for copper SFP like GLC-T
Reference: http://www.cisco.com/c/en/us/td/docs/routers/access/4400/hardware/installation/guide4400-4300/C4400_isr/Overview.html
The Cisco 4331 ISR provides these capabilities:
– One combo port with 10/100/1000 RJ-45 Ethernet port or SFP Ethernet port (labeled GE0/0/0)
– One dedicated 10/100/1000 RJ-45 Ethernet port (labeled GE0/0/1)
– One dedicated SFP Ethernet port (labeled GE0/0/2)
--------------------------------------------------
Also checking the SFP support matrix

Dear Julio,
+5 to the second last post of yours, i degraded to the lowest and then it showed me as below.

Hi
Are you connecting this router to other device into with same speed?
06-04-2018 10:04 AM
The resolution on this didn't work for me. I started playing around and found that I had to actually set the interface to active:
interface gi 0/0/2
ethernet oam mode active
then bounce the port and viola, it came right up. That was ridiculously easy... but also ridiculous that it had to happen in the first place. It should be active by default unless one desired an active/standby setup. At any rate, I hope this can help someone else!

Thanks for this thread. I had a similar problem with a 4331, using a GLC-TE in port G0/0/2. Our WAN provider requires the link to be hard coded to 100/FULL which used to work fine with the GLC-T, but with the GLC-TE the speed and duplex commands were unrecognized even after setting no negotiation auto. After issuing the ethernet oam mode active command and shut/no shut, speed and duplex commands worked and the port could be configured. The oam command must be the default because it does not show in the configuration.
Thanks again for the post.
