Solved: Hi all, I have 2 ASR1001 and - Page 2

Hi there,

we've recently bought a cisco asr 1001 Router and I have a number of interface slots. I want to populate these with fibre modules.

Can you tell me which fibre modules are compatible please? Are the regular SFPs ok to use or is there a special asr series of SFPs to use?

Many thanks,

Paul

Thanks for the info, I was trying to use a GLC-T and could not get the interface UP however I am now using a GLC-SX-MM and it is UP and working. So this information is partially correct

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:

Router1#sh hw-module subslot 0/0 transceiver 0 idprom
IDPROM for transceiver GigabitEthernet0/0/0:
Description = SFP or SFP+ optics (type 3)
Transceiver Type: = GE T (26)

Vendor Name = CISCO-METHODE
Vendor OUI (IEEE company ID) = 00.0B.40 (2880)

Maximum bit rate as % of nominal bit rate = not specified

Router2#sh hw-module subslot 0/0 transceiver 0 status
The Transceiver in slot 0 subslot 0 port 0 is enabled.
Sensor Data is not supported by this transceiver

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?

Regards

Stefano

Hi,

We are having a similar issue with a Cisco ASR 1001-X using SFP-GE-T transceivers.

We have tried multiple transceivers and the link is showing as Up/Up but the copper link does not work (We have fibre links on this router working fine).

We see lots of input CRC errors instead. However if we connect a laptop into the same port on the SP's switch using the same ethernet cable which we are connecting the Transceiver to, the link is working fine.

Is there something you have to do to make this work for normal ethernet on these transceivers?

The SP's bearer is a small Juniper SRX CPE with 100Mbps ports. Auto-negotiation seems to be fine.

Thanks, Andy.

Hi Andy,

I've recently noticed the same thing on my ASR1001-X, however I am using GLC-TE.

When the port is connected at 100M (auto-neg'd), all frames that come in appear to CRC. When connected at 1000M, everything works fine.

I have the ASR connected to a 3560V2 (or any other 100M device) through copper when testing at 100M.

I've noticed that connecting the 3560V2 to one of the SPA ports (SPA-5X1GE-V2), using the same GLC works without issue at 100M.

The issue appears, at least for me, to be limited to the on-chassis ports.
