[c-nsp] Connecting Cisco 3560G to Ceragon Wireless Back Haul viaGigE SFP

[Aaron Riemer]

Hi, 

What is the length of the fibre cable? I assume we are talking LC-LC here if
they are SFP's. The minimum distance for those gbic's is 2M. 

Cheers,

Aaron.

viaGigE SFP

Hello list,
The cisco switch is running bare bones configs. The cragon wireless is a
bridge with a GigE SFP module, multimode.
I am also running with a multi mode cisco sfp
When I connect the two together the back haul equipment's GigE interface
lights up as it should but the Cisco switch remains unresponsive.
all interfaces are unshut and they are set to access mode as well but no
response. Debug shows no info at all neither does the logs or SNMP. it
remains as though nothing is connected.
Anyone come across a similar situation. I am using a Cisco GLC-SX-MM= SFP on
the switch. For the back haul I tried both the Cisco SFP and a generic one
with the same results.
