Can't access switch that's in trunk mode

[whiteford]

Hi,

I have a Cisco ASA firewall, trunked off this I have a Cisco 3750 (128.101.10.52/16) which I can access via telnet from my PC.

Now off the 3750 I have trunked a 3560 (172.24.0.249/16) which I can't access from my PC although I can access it via a telnet session from the 3750.

I have tried adding the "ip route" to the 3750 or ASA's IP but I still can't access.

What do you need from me fo your tom be able to help?

The IP route on the 3750 is 0.0.0.0 0.0.0.0 128.101.10.71 which is our core LAN switch. The 3750 can ping this, I assume the the 3560 needs to ping this too which it can't, it's like the 3750 is not passing the traffic through. I know it is because I have lots of servers on the 3560 which I can access.

Thanks

can you ping the switch from your PC?

No but I can ping, the firewall and the 3750.

In all honesty it should work, don't see why it does not if you say the ASA is not filtering anything.

The only other thing I could suggest - is reboot the 3560, in the past I have issues with switches not being able to reach ip addresses....and a re-load fixes all, but my switches are 3548XL's - so not really a straight comparision :o(

HTH.

NP, it's probably staring me in the face.
