vlan with catalyst 3750

I´m making tests with a catalyst 3750. first i made 2 vlans, then i assign in the next order.

vlan 2 using gi1/0/3

vlan 3 using gi1/0/5

finally made a vlan interface (SVI) of vlan 2 and 3, with the next ip address - vlan 2

- vlan 3

My ethernet card is using /16

when i conect my pc with the port 3 and ping after that there is response , then i disconect and conect it again on the port 5 and ping obviusly there is response again.

But when i ping conected on port 5 theres is no response. Then i type in the conf t "ip routing" because it was disabled, after that,i ping on the port 5 and there is no response.

I would like if someone could explain it.

This could be a cosmetic bug...not sure though...

Re: vlan with catalyst 3750

Your host is having overlapping address

Use for the host and creat a L2 port and L3 VLAN interface for this subnet also.

Enable IP routing.

Note:Any host in perticular VLAN should have the IP address in the same L3 subnet of that VLAN interfac (SVI) in the L3 device.
