Solved: Router SFP media type unknown

ohforce55 · ‎08-08-2017

Hi,

ISR 4331 Router recognizes when plugging in the RJ45 SFP but when I do sh int g0/0/2 (where I plugged the sfp in), it says media=type unknown...

Router#sh int g0/0/2
GigabitEthernet0/0/2 is down, line protocol is down
Hardware is ISR4331-3x1GE, address is 00a3.d186.be22 (bia 00a3.d186.be22)
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

But when I do sh inv, sh do the following command, it shows the SFP....

Router#sh hw-module subslot 0/0 transceiver 2 IDprom
IDPROM for transceiver Gigabitethernet0/0/2:
Description = SFP or SFP+ optics (type 3)

sorry that's your correct sfp below and it should work on 3.13 IOS version also as per doc

SFP-GE-T

Yes

16.4.1

3.13

10/100/1000BASE-T SFP (NEBS 3 ESD)

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)

Hi

Its supported sfp but you need a minimum version for that sfp , are you running the below or higher ?

Hi,

Thank you so much for your reply.

You mean IOS?

My company's recommendation is to have 3.13.7S.

Will that work with the IOS 3.13.7S?

I would try the 3.13.7S as its on 3.16 see if it makes a difference and see if it gets recognised

ohforce55 · ‎08-08-2017

Thank you again!

The thing I'm wondering is that the doc shows minimum IOS. The IOS that is in the router has higher version....

Why isn't it worked? Is it related only with SFP?

Mark Malone · ‎08-08-2017

Hi

could be a number of reasons most likely software related , that 3.16 is a fairly good version though my GLC-Ts worked fine in it but we had issues on some earlier images where only v2 sfps would work and not v1 that was stamped on the actual sfp sticker on the back of it

Also make sure its cisco branded sfp and not a 3rd party type as some of them don't work at all either

there's been a few discussions on the 4331s and different types of sfps not working usually comes down to some firmware or software version miss-match between the sfps and router

I have one more question :)

Media type is now shown as T

The unknown is standard and you want to see T as its a base T SFP so your good :)

Thank you!

Hi Mark,

After rebooting the router, the media type is not shown...

It said 'T' before but now it is gone...

Router#sh int g0/0/2
GigabitEthernet0/0/2 is administratively down, line protocol is down

Mark Malone · ‎08-15-2017

Hi is it still the same if you bring the interface up , its admin down ? it was working so strange reboot would cause an issue , still on same software yes , it didn't roll back ?

ohforce55 · ‎08-15-2017

ah.... hehe

after no shut, it works... :)

thanks!

After downgrading to 3.13.7S, it works!!!

Thank you!!

But when i insert the SFP module it is not showing in Inve? Router#sh inventory also port is showing down..

Pls suggest

thanks
