VLAN Routing on Catalyst 3560

[scottcummins]

Good day All

well, I have a simple one but I do this so seldomly I forget. I have an access layer switch with a single VLAN - VLAN 100 (3500 XL, yes it is old) and I have trunked that traffic to a distribution layer switch (Catalyst 3560), I IP'ed three VLANs on the Distribution layer VLAN 100, 125 and 252. From a device plugged into the access layer, I CAN ping the gateway IP for VLAN 100 but not the other two VLAN gateway IP's. I know it is simple, I just need a push. what am I missing? VLAN 1 is NOT shutdown

Also, I want to forward any traffic not bound for VLAN 100 or 125 to VLAn 252 which is connected to a port on a router, iss the statement "ip route 0.0.0.0 0.0.0 172.16.252.2" good enough?

You need to enable "ip routing" on the 3560, make sure it is running the appropriate IOS not the LAN base.  You need the IP Servers etc.  And the upstream router IP is 172.16.252.2 I assume so yes on the 3560 you will run that command.

Also on the 3500XL make sure that you setup a trunk port and connect that port to the 3560 and setup a default gateway.

Crap, I am running the IPbase IOS

On on 3560 did you enable routing?

conf t

!

ip routing

On 3500 XL did you configure the trunk port and connected it to the trunk port on 3560 and setup a default gateway?

Scott,

May be easier to help if you could post both switces configs

3560:

conf t

!

ip routing

*** This will enable IP routing on the 3560

Then lets say port gi0/48 on 3560 you will setup a trunk (note:  I'm giving you a very basic config you can tweak it once all is working)

interface gi0/48

sw mode trunk

*** This will setup the port as a trunk port

3500XL:

conf t

int gi0/48

sw trunk encap dot1q

sw mode trunk

!

ip default-gateway x.x.x.x (this would be the IP of VLAN 100 on 3560)

  What is the status on the 3560 when you do a show ip int brief?  Does it show the other 2 subnets in a up/up state?  Do a show vlan do all of your vlans show active ?.  You must have at least one active port in each vlan for the SVI to be in an up/up status or a trunk linkl with those vlans in it .

I think that is it, I forgot in order to have an active VLAN, it has to have an active port, I don't have anything plugged into the other VLANS, I will get something going and then see if I have an issue. Thanks Guys for all the help, I really do appreciate it
