Hello, I would like to use my 3750 switch as a level 3 switch so I can route between vlans.
Please reference the config below.
I currently have 5 vlans set up. Just for test purposes I have a PC in VLAN 2 and a PC in VLAN 6.
Vlan 2 IP address is 192.168.1.1 255.255.255.0
Vlan 5 IP address is 192.168.5.1 255.255.255.0
The PC on VLAN 2 has the ip address of 192.168.1.2 255.255.255.0 default gateway 192.168.1.1
The PC on VLAN 6 has the ip address of 192.168.5.2 255.255.255.0 default gateway 192.168.5.1
I have enabled ip routing in the config.
Niether PC can ping the other, with the PC in Vlan 2 giving this message ?Reply from 192.168.1.1: destination host unreachable
And the PC in Vlan 6 giving this message : Request timed out
Can anyone tell me where im going wrong?
Many thanks.

Hi,
Have you actually created the VLANs using the VLAN database ?
If not, enter VLAN configuration mode using the command 'vlan database' and then create both of these VLANs.
Hope that helps...
Paresh.
PS. Pls do remember to rate posts.

No i havent, how do i enter vlan config mode?
Many thanks
08-17-2006 02:50 AM
Simply enter in the command 'vlan database' from the privileged exec mode i.e. from the switch# prompt. You do not need to enter configuration mode.
Then enter in the following commands:
vlan 2
vlan 5
Both the VLANs will then be created with default paramaters...
Hope that helps - pls do rate the post if it does.

This does not seem to help, i saved the config and rebooted the switch and PC's and i still get the same results.
Any ideas?

Can you post the output of:
- show vlan
- show interface vlan2
- show interface vlan5

hi micheal,
with your posting, i havn't seen any of the ports having "switchport access vlan 6", since your trying to ping from vlan 2(192.168.1.2) to vlan 6(192.168.5.2) pc, you need set "switchport access vlan 6" on the port where 192.168.5.2 pc is connected.this could the reason for not pinging.
hope this helps.
rate this post.

Michael,
Can you try and configure 'switchport mode access' under the interfaces that are connected to the PCs that you are testing from ?
Paresh
08-17-2006 03:34 AM
I have added switchport mode access on ports 1 and 47.
What does this command do? Im trying to understand in order to configure properly.
thanks.
Mike.
08-17-2006 03:35 AM
By default, switches will try and form a trunk over the link if possible. This command hard-cores the interface to function solely as an access port.
Paresh
08-17-2006 04:43 AM
Ok thanks for that, i still get the same results. No luck.
IS the config correct in principle?
I am working from this link, but obvisouly my set up is simple comapared to the cisco site.
