I've attatched the packet tracer file to see if anyone can figure out why
I can't communicate across vlans. Pretty sure its a simple fix for you wizards out there.
Solved! Go to Solution.

Any chance you could post as a doc or something because not all of use packet tracer.
Things to check -
1) from a client in vlan 10 (for example) can you ping the vlan 10 SVI address
2) from a client in vlan 10 can you ping another SVI ip address on the switch
3) do you have the correct default-gateways set for the client
4) any access-lists configured
Jon
Check default gateway on the client and subnet mask
Can you ping yourself (on both the router and the pc)
Is the pc in the right vlan?
sho mac-address
sho ip arp
Both are your friends
Hi,
In each VLAN the gateway was unaccessible so there was surely a problem on the link between the 3560 and the 2960.
Logging into 3560, the VLAN interfaces were up/down.
Resolution: on the 3560 change the f0/1 back to a L2 port with the command switchport --->the nterfaces go up/up
Then a native vlan mismatch message appears on the 3560: vlan 1 on this side and vlan 99 on the other side
Resolution: on f0/1 put these commands
-switchport trunk encapsulation dot1q
-switchport mode trunk
-switchport trunk native vlan 99
Regards.
Alain.
