[srikanth ath]

Quick suggestion

I have L3 switch cisco 3750

i have configured two vlans assigned ports to it

. when i connected PCs to two ports of different VLAN , lets say PC1 in vlan 30 i can ping to different vlan ip gateway i.e 10.10.17.1 but couldnt ping  to the PC connected to vlan 40 (PC 2 10.10.17.2)

i know this is intervlan routing , but couldnt find a solution for this .. can any one of you sugest

i have enabled IProuitng

###

#sh ip route

     10.0.0.0/24 is subnetted, 3 subnets

C       10.0.1.0 is directly connected, GigabitEthernet1/0/12

C       10.10.17.0 is directly connected, Vlan40

C       10.10.16.0 is directly connected, Vlan30

VLANS:

interface Vlan30

If you can ping the other PC's default-gateway then it sounds like the 3750 is setup correctly.

Check your PC's for firewalls that could be blocking the ping requests either Windows firewall or possibly AV software.

From PC in vlan 30 can you ping vlan 40 vlan interface IP ?

From PC in vlan 40 can you ping vlan 30 vlan interface IP ?

If no to either then -

1) check default-gateway and subnet mask on each PC

2) check the ports the PCs are connected into are set to the right vlan

if yes to both then -

from switch can you ping PC in vlan 30 and vlan 40

if no then recheck PCs

Hi Srikanth,

If you are able to ping the vlan gw from other vlan then the L3 inter vlan routing is fine.
Make sure the pc is configured with correct IP and DG from which you are trying to ping other vlan pc's
