Can ping device from swith, not from my pc

[dips00]

Hi,
I have a cisco 3550 with 4 ports used to connect 4 different devices (10.1.10.1/2/3/4). I can ping all 4 from the switch without a problem. I can also ping all 4 in a workgroup environment using a small 5-port switch and a laptop.

But from my desktop, i can only ping 10.1.10.1 & 2. I cannot ping 3 & 4.

They all are in the same vlan.

Any advice will be appreciated.

whats the config of the switch? is there a firewall on those hosts? or your desktop? are those ports in the same vlan? what is the IP of your workstation?

 

[dips00]

No firewalls on the switch. The ports are on the same vlan. My desktop ip is 10.111.x.x. But whats got me confused is from the same desktop, i can ping 10.1.10.1 & 2.

Both ports are configured exactly the same with the access to vlan 119.

Thanks.

is this through a layer 3 switch? what is your route statements look like? are there access lists? can you post a config of the switch?

 

[dips00]

Layer2.
No access lists. The config is below.

you can not ping 10.1.10.3 and 10.1.10.4, what interface are they on? i dont see one. i only see fa0/25 and fa0/26

post sh vlan or make sure .3 and .4 are configured correctly

 

[dips00]

correct, .3 is on fa0/25 and .4 is on fa0/26.

so where is 10.1.10.1 and 10.1.10.2 configured? what ports?

 

[dips00]

.1 and .2 are fa0/23/24.

I am wondering if the gateway can be configured incorrectly.

Are you using a router for inter-vlan routing or is there any inter-vlan routing? I see you said your desktop was 10.111.x.x and you can ping the switch which is at 10.1.10.1 on vlan 119. Also i dont think you have to have a port dedicated to the switch, such as fa0/23 for vlan119(you stated you had 10.1.10.1 on port0/23), i think it is just logically assigned. Or is there a device connected to the port fa0/23-0/25. If so maybe there is a ip conflict with the switch being assigned 10.1.10.1 and another device.

You've left out much relevant config from your switch, making it more difficult for people to advise you.

Your devices on 10.1.10.3 & .4 have an incorrect default GW setting.
They are pingable from the switch because the switch is configured as a router and *presumably* has a VLAN interface configured with a 10.111.x.x subnet address.
