cisco 3560 layer 3 switch question

Hi,

I'm new in cisco networking. I have 3 cisco 3560 layer 3 switch. I defined the vlan as follow: (vlan1 is the manangment vlan) I can ping from server1 (on switch1) to server2/server3 (on switch2).

I can ping back from server2 (on switch2) to server1 (on switch1). I can ping back from server3 (on switch2) to server1 (on switch1).

I can ping from server4 (on switch3) to server2/server3 (on switch2). I can ping from server4 (on switch3) to server1 (on switch1).

I can ping from server5 (on switch3) to server3 (on switch2). But I found I can't ping from server5 (on switch3) to server2 (on switch2). OR I found I can't ping from server5 (on switch3) to server1 (on switch1).

My question is, Is that possible to make a connection between server5 (which is on vlan4 of switch 3) to the server1 or server2 (which is on vlan2). ( Certainly , I can ping from server5 to server4.) ====================================================================== [switch1] vlan1:180.40.1.254 vlan2:180.42.1.254 {port 1-23}

[switch2] vlan1:180.40.1.253 vlan2:180.42.1.253 {port 1-12} vlan3:180.42.33.254{port 13-22} vlan4:180.42.31.253{no port assigned) [switch3] vlan1:180.40.1.252 vlan2:180.42.1.252 {port 1-12} vlan3:180.42.33.253{no port assigned} vlan4:180.42.31.254{port 13-23}

(vlan 2)

------------------------------------- (P.S. All server have the default gateway to the corresponding vlan segment)

Thank you very much for any help,

You are talking about a layer 3 issue it sounds like. Where is the router interface for VLAN 4? Can server 5 ping its gateway? How about ping server 4 on the same switch? If not, you need to check trunking of vlan 4 back to the router that owns all these networks.
