Cisco 3400 Input Packet 0

[jawwadahmedqureshi]

Dears,

We re using Cisco 3400 in out network with Metro Ip Access 12.2(53)Version.

The issue is that we Plug SFP SFP-GE-L 10-2144-01,1000 BASE LX/LH and loop the Fiber Patch Cord we do not recieve any packet.

Even if we connect to other Cisco we are unable to recieve packet even the Interface status Shows UP..

Need your expert advice.

Thanks

Jawwad

Hi Jawwad,

do you mean that the issue occurs ONLY if you use SFP SFP-GE-L and not if you use other SFPs?

If this is the case, which other SFPs did you try?

What do you see on 'show interface gix/x" after you send some traffic? can you attach the outputs?

All ports are affected or just some?

Can you attach the port configuration?

regards,

Riccardo
