ISR 4331 interface

[jack samuel]

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

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

[jack samuel]

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.

[jack samuel]

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

[Julio E. Moisa · Accepted solution]

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

https://supportforums.cisco.com/discussion/13025801/4331-transceiver-not-supportednot-compatible

I will  search more information. 

[jack samuel]

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

Cisco 4331 ISR

The Cisco 4331 ISR provides these capabilities:

• One single-wide SM slot
• Two single-wide NIM slots that can combined into one double-wide (NIM1 and NIM2).
• One 10/100/1000 RJ-45 Ethernet port for system management (labeled {MGMT} on the right of the connector)
• One USB Type A host port
• One USB mini-Type B console (placed next to the RJ-45 console port)
• One RJ-45 console port
• One RJ-45 auxiliary port
• Three GE ports allocated among two RJ45 and two SFP as:

– 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)

Dear Julio,

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

Can you confirm you can use an SFP to terminate SMF on a 4000 series router? Trying to do it on a 4331 and the port will not come up. SFP is detected and port has link light but still shows down/down.

[Julio E. Moisa]

Hi

Are you connecting this router to other device into with same speed?

[j0shmans]

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.
