Switch can't comunicate with server

[kacperzyb]

Hi,
I'm experiencing an issue with communication between my TFTP server and switches. Routers and PCs can ping the server, but switches cannot. So, my question is: can the server block ICMP from the switch, and if so, how can I fix this?
This is how my network looks

Switch2 works on VLAN1 and network address is 160.0.0.0/26
TFTP ip is 160.160.0.5
This is my first post here, and I'm still learning, so please be patient. I apologize for any mistakes in advance. Thank you!

Hello @kacperzyb 

Switch2 have got an ip address on vlan 1 ? Under an interface vlan 1 ?

[kacperzyb]

It may not. How to check it?

[Richard Burts]

show ip interface brief is the best way to check it. also the output of the command show arp would be helpful.

@kacperzyb 

Basicly do #sh run command and check at the end if you have interface vlan 1 configured or not.

Or do #sh ip interface brief command in order to list L3 interfaces.

So it didn't have the address, now after assigning it, pings from switch2 are coming, but they are not from switch1.

I am somewhat confused. In the original post it sounded like no switch was able to communicate with the tftp server. But then there was a comment that switch2 was able. 

This most recent post, with the output that we requested, does seem to show that there is connectivity. It appears to be output from switch2 and confirms that switch 2 is working. It indicates that switch1 is not working. So now we need information from switch1. Output of show ip interface brief would be important. Also indication of whether switch1 has a default gateway configured would be important. You might get that using the command show run | include default or you might get it from the output of show ip route.

OK @kacperzyb 

As concerned Switch1, which vlan is hosted ?

Supposing that gateway of pc 0 and 1 is hosted on Router0, add interface vlan X on the switch and add ip default-gateway a.b.c.d, with a.b.c.d the Gateway on Router0.
