Hi,

I need some help on an older Cisco ASR-1001, NOT the X or what not, the plain ASR1001 router with the SPA board and the XSP module in it to connect to a SFP+ 10G module.

I got the fiber modules form FS (XFP-10GLR-31) and the site clearly say it isa multirate type and compatible with either the 192SR-L or the 10Gb, but I can't get it to actually work with ANY SFP+ yet. I contracted the FS support and they did say it is suppose to work and I return it twice so far as they said I had the wrong coding it them, etc. So it's been 3 different times so far and I have 5 routers with 3 different SPA module and 4 XSP and I try every possibility os it is NOT the routers that are bad or the SPA or the XFP, etc. Not possible that every thing is blown up!

But I can't get it to work.

Somehow looks liek the encoding is always for the SONET 192 type and NOT for the Ethernet 10G on the SFP+.

I have the other side of the link connecting to SFP+ either on Arista or Cisco switch with the respective SFP+ on each hardware and no go.

IBX-2#show hw-module subslot 0/1 transceiver 0 idprom brief
IDPROM for transceiver TenGigabitEthernet0/1/0:
Description = XFP optics (type 6)
Transceiver Type: = OC192 + 10GBASE-E (174)
Product Identifier (PID) = XFP-10GER-OC192IR
Vendor Revision = 03
Serial Number (SN) = ONT1133100A
Vendor Name = CISCO-OPNEXT
Vendor OUI (IEEE company ID) = 00.0B.40 (2880)
CLEI code = CNUIAKUAAA
Cisco part number = 10-2189-01
Device State = Enabled.
Date code (yy/mm/dd) = 07/08/14
Connector type = LC.
Encoding = 64B/66B
SONET Scrambled
NRZ
Minimum bit rate = 10000 Mbits/s
Maximum bit rate = 10300 Mbits/s

The link just do not want to come up no matter what I do.

Been over a month now and I am still at a lost.

Even in a loopback mode I get up/down constantly:

*Dec 31 20:48:56.665 EST: %LINK-3-UPDOWN: Interface TenGigabitEthernet0/1/0, changed state to up
*Dec 31 20:48:56.665 EST: %LINK-3-UPDOWN: SIP0/1: Interface TenGigabitEthernet0/1/0, changed state to up
*Dec 31 20:49:00.971 EST: %LINK-3-UPDOWN: Interface TenGigabitEthernet0/1/0, changed state to down
*Dec 31 20:49:00.971 EST: %LINK-3-UPDOWN: SIP0/1: Interface TenGigabitEthernet0/1/0, changed state to down
*Dec 31 20:49:05.311 EST: %LINK-3-UPDOWN: Interface TenGigabitEthernet0/1/0, changed state to up

I try to see if I can force the encoding to NOT be SONET, but if that's possible to do, I sure do not know how.

As for the interface itself, it does show:

IBX-2# sh int te0/1/0
TenGigabitEthernet0/1/0 is down, line protocol is down

If anyone would have a clue stick to offer I sure would be very grateful as I am lost.

What I did just a few minutes ago is order on EBAY and Cisco XFP for this SPA just in case the coding from FS is still not right as I have no other ideas to try.

Wil see if that actually will work.

But everything I read tells em that I can hve XFP on one side and SFP+ on the other side working at 1310nm single mode and as such I should be able to use standard SFP+ on a Cisco switch or an Arista switch and the other side of the link being connected to the XFP on the Cisco router.

Am I missing something or is this really not suppose to work?

Thanks for your time.
