I am hoping I only forgot how to do this, otherwise my Sup is bad....

to make a Sup 1A with a MSFC card route, I am using a hybrid... cat os and ios on the L3 card.

All need to do is in
Cat IOS... create the vlans and assign the ports.
On the L3 card, create the VLANS.
Right?
on the first VLAN I created it can ping the Ip of any of the VLAN interfaces.
but the second VLAN can ping nothing.

did I forget a step?

That is the basic procedure, but in order for you to ping another vlan interface, that vlan must be "up" and in order to be up, at least one port must be assigned to that vlan and have something attached to that port.

Looks like my sup might be bad then.....

Both VLANS show as up
ports are assigned to the VLANs
the ports show as up, and in the correct VLAN
the VLANs show as up
but no inter VLAN traffic will pass
I have even double checks, addresses, masks, gateways.. all good

What is the status of the VLAN interfaces on the MSFC?

Here's how I explain the process.

1) create the VLAN "set vlan 10"
2) assign ports to vlan "set vlan 10 3/4-8"
3) create SVI (VLAN interface) on MSFC "config t" then "int VLAN 10"
4) assign ip address to VLAN interface "ip address..."
5) enable the interface "no shutdown"
 
Repeat for other VLANs.

From the MSFC, can you post result of "show ip int brief"
And "show ip route"
Make sure ip routing is enabled

thats what i was afraid of, that's exactly what I did.

So no little option on the Cat OS side to make the card function.

when I show mod, all the cards so as up.

thanks for the help

You don't make the MSFC function from CatOS.

When you issue the "show mod" command, you should see the MSFC. Most likely on slot 15.

Then use the "session 15" command to access the MSFC command line. Then configure it like you would a router. (except the interfaces are all VLAN interfaces)

yeah that is what I did, just have not traveled back in time in a while, most of the 6500's I configure are sub 320 or 720.  but this is an emergency and that is all Have on hand.

so off to find another sup.

Have you verified that ip routing is indeed enabled on this one first?

Wait a minute...

Why do you think that you need new sup???

When you do a "show mod" does the MSFC or sup show that it's not "OK"?

Everything shows up,
sho mod,,, all the mods are up, all the sub mods are up
all the interfaces are up
all the VLANs are up
sho ip route shows all my interfaces as connected.
Everything looks good, but no traffic flows between the VLANs
both of you outlined exactly what I did.
and nothing works.
I have even checked to make sure all my modules are compatible with each other.
I am going tomorrow where I will have an additional Chasis, 10/100 modules, and another Sup and MFSC

Have you confirmed that ip routing is enabled. When in doubt, issue the "ip routing" command from global config.

Can you ping any connected devices from the MSFC?

Can you post the config of the MSFC.

In hybrid mode the are virtual trunks to the route processor, I guess you checked to make sure that all appropriate vlans are trunked over the virtual trunks as well?
