Hi there
I am using HWIC-1GE-SFP on 2811 ISR. the Gig port seems up but cannot ping the other end and does not send any traffic.
any help is appreciated.

Hello Mohammed,
please post
sh run int gix/y
sh int gix/y
sh ver | inc image
is the module recognized by your router?
what is connected on the other side of the fiber link?
check the type of SFP used in both ends and the type of fiber
Hope to help

Hi
the module is recognised. it is up when i see in the sh ip int bri.
other side is the fiber to copper media converter.
GLC-T copper SFP module is connected to the HWIC.
sh run
interface GigabitEthernet0/3/0
ip address XX.XX.XX.XX 255.255.255.252
no negotiation auto
end

Hello Mohammed,
keepalive is set
but
>>Last input 22:04:16, output 00:00:02, output hang never
and the interface is up/up
This is strange.
IOS version is new.
I will try to look at GLC-T support
what if you shut and then no shut the interface.
Hope to help

thanks for your reply...
i tred to do that it does not work. i did change the GLC-T SFP but no luck. and yes the HWIC 1GE-SFP does support GLC-T. i did verify this with the cisco document.

There's output traffic but no input traffic. You sure you don't have an ACL on either side of the /30 subnet?
10-19-2009 09:08 PM
Hi
the /30 link is t the ISP. there is n access lists.
Also the cable is connected to the media converter. I do not see any link on the media converter. however if I connect any other device on the Meda converter, its working perfectly OK.
is there any special config required on the Media converter except the normal interface configuraton?? does HWIC-1GE-SFP with GLC-T work?
10-19-2009 09:31 PM
Media converter? Why don't you just get a fibre optic SFP instead of the GLC-T?
10-20-2009 01:14 PM
Maybe it's because with the GLC-T, it won't negotiate duplex and speed. If you move the copper connection to the media converter from the GLC-T to any one of the RJ-45 of your routers (including the config), will you be able to ping across the /30 subnet?

I'm having the same issue. What did you do to resolve?
