SFP-GE-T not working on ASR1001

[s-durando]

Hi all,

I have 2 ASR1001 and I'm trying to bring up a direct link between them.

The SFP that I used is SFP-GE-T which is supported.

ASRs are running the recommended IOS XE release 3.7.6S.

The config of both interfaces is extremely simple:

interface GigabitEthernet0/0/0
 ip address xxxx
 negotiation auto
 no shutdown

!

The SFP are recognised and seems to work well:

I already tried to:

- change RJ-45 cable

- use cat 6 and cat 5e cables

- disable and enable autonegotiation

- move the config to another GigabitEthernet port

I haven't any spare SFP-GE-T so I couldn't try to change them.

On the same routers I have another port (GigabitEthernet0/0/3) with SFP-SX-MMD and it is up and running.

Any suggestion?

interface GigabitEthernet0/0/0
 negotiation auto

ASR don't support auto negotiation.  You need to specify the speed and the duplex settings.  

Post the picture of the SFP as well if is still doesn't work.  There are certain hardware revisions of the SFP that the ASR supports.

Hi Leo,

thanks for your support.

I already tried to disable auto negotiation and specify speed and duplex settings.

Now I'm going to check hardware revision of the SFP as you suggested.

[Leo Laohoo]

Look at the SFP.  Did you see the value 30-1421-04?  The "04" is the hardware revision number and it should be supported.  

I think you need to raise a TAC Case.

[s-durando]

Hi Leo,

I used another SFP-GE-T with part number 30-1421-01 and it works fine.

Anyway the SFPs with part number 30-1421-04 are not broken. I tested them on a Catalyst 3750 and they work fine.

Maybe there is an incompatibility between ASR 1001 and SFP-GE-T with part number 30-1421-04.

Go HERE and scroll down to Table B-8.  See the part number?  It's for a 30-1421-01.  So I was wrong when I said that the "04" is supported.  

If you need to order more, make sure you specify to the vendor the SKU code of "30-1421-01".

Dear s-durando,

Were u able to solve the SFP-GE-T and ASR 1001 incompatibility issues.

[s-durando]

Yes I solved the problem by replacing with GLC-T with hardware revision number (or TAN = top assembly number) equal to 30-1421-01.

Hi Leo,

I attached the picture of SFP.

How can I verify if hardware revision is not supported?
