Connection issue with 3750

Hi,

I've configure a catalyst 3750 (see config below) with a vtp trunking port (int gig 1/0/1) which links up to a 6500. I get link lights on the interfaces on the 3750 and 6500 but I can't seem to do anything else from or to the 3750 i.e. pings, telnet sessions.
I've set the vtp domain to client, configure the vtp domain and password to match the one of the 6500.
We've other switches which are working fine and have the same config, apart from different hostnames, ipaddresses and native vlan uplink numbers.
I'm quite new to cisco products so forgive if i'm being a bit vague. But please let me your thoughts.

Thanks

It looks like your default-gateway is incorrect on the switch should be pointed to the address on the far end that feeds vlan 1000 , 10.0.57.X . You can only use the default-gateway if you have turned routing off on the 3750. If you still have routing turned on then you have to get rid of the default gateway and use a static route 0.0.0.0 0.0.0.0 10.0.57.X .
 
on the gig trunk interface you have "switchport trunk native vlan 520" is that correct as you have int vlan 1000 with an ip address.

CCNA, CCNP..partly ;)
 
I've actually diagnosed the problem to a faulty sfp port on our 6500. I tried a different sfp port on another card and hey presto! it worked.
I should have tried that first before posting!!!
However, i tried other ports on the same card (i.e. 3,4, 7 & 9) all of which didn't work but I have exsiting equipment in ports 1 & 2 which work. I'll do some more testing and swap the card and I'll post if I have any further problems.
But for now, thanks to everyone who replied
