Re: C1000 to C1000 SPF+ C1000-48P-4X-L

IT2022 · ‎06-22-2022

Hello,
we want to connect two C1000-48P-4X-L switches over fiber and are using the following transceivers (10GTek 10G SFP+ SR Multimode Modul - 10GBase-SR LC Transceiver Kompatibel für Cisco SFP-10G-SR).
Transceivers are shown and recognized but do the LEDs by the GBICs have to blink and what type of port do we have to configure, we have set trunk.

Regards

- For starters, have an in-depth check of sfp-compatibility with : https://tmgmatrix.cisco.com/

We had a look before we bought the transceivers. The current inserted have the supported IEEE 10GBASE-SR standard.
850nm, 300m MMF.

Is there anything I do miss?

- If they are not Cisco, success is not guaranteed you may use commands as
no errdisable detect cause sfp-config-mismatch
no errdisable detect cause gbic-invalid

Not sure if that will help

I did connect both switches directly via LC/LC cable and that did work.
Then I moved one switch to the other location, connected via SC/LC - no link is comming up. Then I ran the commands above, wr mem and did a reload on both switches. No link after the restart.

Now I guess it could be something with the inhouse lwl cable but it was tested already by lwl technician.
Maybe the lengh is too high? I have no further ideas.
