I have a stack of three 470-48T switches cascaded and I have a gigabit
modual in switch 1 and 3 and I have a multi link trunck set up and two
fibers going to my core from the switches.
My fibers are going into the core, one is on the 172.16.x.x vlan while
another is on the 192.168.1.x vlan.

All ports that are members of a Multi Link Trunk must be in the same
VLANs or things won't work right. All MLT port members must be
configured identically.

I have a number of vlans running out of my 8600 core a 204.80.158.x,
172.16.0.0, a 172.16.32.0 and 192.168.1.0.

Ok, so call 204.80.158.x VLAN 1, 172.16.0.0 VLAN 2, 172.16.32.0 VLAN
3, and 192.168.1.0 VLAN 4. The actual VLAN numbers you use must match
those that are used on the core switch.

My question is with the switch stack IP of 172.16.16.76 can I push out
all my vlans to the switch group and then say make ports 1 through 24
vlan 204.80.158.x and ports 25 through 40 vlan 172.16.32.x and ports
41 through 48 vlan 172.16.16.x can I do this push my vlans out to
the port even though the 470's are layer 2 switches I heard I can do
this....is that right and how would I do it?

I guess how do I pull down all the vlan info from my core to the stack
and then go from there?

You don't "pull down" VLAN info dynamically. You configure all the
VLANs statically, first for the trunk:

vlan port 1/48,3/48 tagging tagAll
vlan members add 1 1/48,3/48
vlan members add 2 1/48,3/48
vlan members add 3 1/48,3/48
vlan members add 4 1/48,3/48
vlan port 1/48,3/48 pvid 1
mlt 1 member 1/48,3/48
mlt 1 enable

Then the user ports e.g. on stack unit number 2:

auto-pvid
vlan members add 1 2/1-24
vlan members add 3 2/25-40
vlan members add 2 2/41-48

OK I am doing this all through the console, can I do that?
I've setup my mlt and that seems to to working, my stack ip is
172.16.32.14 and my mlt is plugged into the core and on vlan172_32

my vlans are:
vlan172_0
vlan172_16
vlan172_32
vlan192
vlan204

I've created vlans on my stack named the same as on the core eg:
vlan172_16 etc, and made them active

I created the vlan192 and set port 3 on switch 1 to it, even though
the whole stack is on the vlan172_32
I then plugged a PC into port 3 on switch one and tried to pull a
192.168.1.x address and it would not get one. I then statically gave
it an address of 192.168.1.119 and still I had no access to my
netowrk.

If I plug something into the switch ports and give it a 172.16.32.x
address I am fine and can get on the network.

Why is my vlan192 not getting through to port 3? Any ideas?

thanks.

You should set the same VLAN for 192 on core switch.
After it, set the ports or MLT on ES470 and core switch as trunk port.
Finally, set DHCP relay (IP helper) on your core switch to let your
clients in VLAN 192 can get IP address from DHCP server.- Hide quoted text -

My core has all my vlans on it, I can make any port on the core any of
my vlans.
I put my fibers into ports 4 and 6 on the core, I then set core ports
4 and 6 to vlan172_32 because my stack IP is 172.16.32.14

If my switch stack IP was: 192.168.1.14 I would make ports 4 and 6 on
ports be vlan192, but my switch stack has a 172.16.32.14 address.

Now when I am plugged into the fiber my 3 switches in the stack all
work, meaning any PC plugged into any switch and any port on the
switch can be assigned a 172.16.32.x address.

But I want to for example plug PC into switch 1 of my group and ports
3 through 20, I want to be able to plug in computers with a
192.168.1.x address .....When I goto switch 1 and choose to make ports
3 through 20 vlan192 it seems to work but If I plug a 192.168.1.x PC
into one of those ports it can not get out on the network...its like
the 192 is not being passed to those ports.

any ideas?

For your question, I would like to know what you set for port 4 and 6
of the core switch. I assume that you only assign port 4 and 6 of the
core switch to VLAN172_32 and use fibers to connect to the ES470
stack. The packets of VLAN172_32 can go to core switch through ES470
because you set port 4 and 6 to VLAN172_32. If you want the packets of
VLAN192_168 can also go to core switch, you should also set port 4 and
6 to VLAN192_168 on core switch. As the result, port 4 and 6 on core
switch will be the members of both VLAN172_32 and VLAN192.168 as trunk
ports. These can be done by 802.1q tagging on ERS8600 and ES470.

For example, the port members of VLAN's should look like this when you
use port 2/48 and 3/48 to connect to ERS8600;

ES470-48T stack
VLAN172_32 : 2/1-3/48
VLAN192_168: 1/3, 2/48, 3/48
(2/48 and 3/48 are trunk ports and MLT members)

ERS8600
VLAN172_32 : 1/4, 1/6
VLAN192_168 : 1/4, 1/6
(1/4 and 1/6 are trunk ports)

On ERS8600, turn on the DHCP relay on the interface IP of VLAN192_168
and setup relay agent IP address.- Hide quoted text -

When I turn on Perform Tagging for Ports 1/4 and 1.6 on my core the
470 stack goes dead, meaning I can no longer see it on my network.
