VLAN on Dell N4064 Stacked

@Pete-S said in VLAN on Dell N4064 Stacked:

Stacking will make it work as one switch and you make config changes on the master.

Ports will be named for instance Gi1/0/2, which is port 2 on switch 1 in the stack.

So, can Gi1/0/2 (interface two on stack member 1) have default of vLAN1, and vLAN20? If something is plugged in with no tag, it gets 1, if its tagged with 20, it gets vLAN20?

VLAN configuration has not much to do with IP addresses really.

You can put ports that have connections without any vlan tagging to access mode.

Yes. You have to set the port to general mode then.

Port has to belong to vlan1 and vlan20. pvid is set to 1, which means that untagged traffic automatically belongs to vlan 1.

You should be able to set the untagged and tagged VLANs to whatever VLANs you want on whatever port you want. Unless, it is a management port, then sometimes, they won't let you change that.

Look for the Dell EMC Networking N-Series CLI Reference Guide pdf.
It has all the commands for the N-series Dell switches.

Something like this:

interface Gi1/0/1
switchport mode general
switchport general pvid 1
switchport general allowed vlan add 20 tagged

Also don't forget to save the config when you're done or it is gone if you reboot the switch.

@Pete-S If the N are like the powerconnect line, you might even be able to do this in the web UI. If you are more into that. Obviously, it is much faster to change lots of ports at once in the CLI.

Yep, makes sense. In theory I could set every interface on the whole stack to mode general, pvid1 (so vlan 1 is default if no vlan is set on the device) and all interfaces also vlan 20 allowed. Now, I can have a DHCP on vlan20 to hand out addresses on the switch to the 10.10.x.x network, and DHCP on vLAN1 (or no vLAN set) to provide DHCP to 192.168.x.x network?

Am I able to allow interface 1-10 pass traffic from vlan 1 to vlan 20, whilst telling 11 - 20 to not pass traffic between vlan?

Good point. Yes, I think all the N-series switches have the web GUI too.

When it comes to configuring the stack, I assume I connect by COM/Putty to the unit I want as master, boot it with the CLI, update firmware and restart. Then, go through the setup wizard, set my vLAN1/management/etc, then set the 40GbE interfaces (2 of them) to be 'stack' mode. Save then turn off.

Once that is done, connect to switch 2 and 3 in turn, update the firmware, run through the setup wizard but set no vLAN/etc as its not needed (as they will get that from the master when connected?), but do set the 2 x 40 GbE on each to 'stack'. Then turn them off.

Stick the stacking cables in. Finally, turn on the first one and let it boot, it would be master. Once that is up turn on the second switch, as it boots the master will push the config (setup at the start of this post), and finally the third once switch 2 is up...

I have not done that yet, will on Monday - but am I missing anything?

@Jimmy9008 Is that what the docs say the procedure is? I would imagine you would want to have all the switches at the same firmware level prior to adding them to the stack.

Yeah, they need to be the same firmware. The documentation is very light on setting up a stack.

I am pretty sure that is the process though.

Can I use the CLI to create a DHCP server running within the stack on vLAN20?

I did some stacking on N-series not too long ago.

Dell have some info on their site:
https://www.dell.com/support/article/se/sv/sedhs1/how10357/how-to-stack-and-unstack-a-member-in-dell-emc-networking-n4000-switch?lang=en

There is also some stacking videos on youtube. It's not too complicated but it requires some power cycling.

PS. Can't help you on DHCP and routing. I haven't done much L3 stuff with these switches but I assume it will work.

Thats pretty much the process that I have in mind. The part im not sure about is between step 1 and 2. To get to the part where you can configure the interfaces as stacking interfaces, you have to go through first boot and setup the switch... (does all of that setup get removed when they become stack members?)

I didn't do any update of the stack firmware I just checked that they had the same version. It's a lot easier to update the firmware after they are stacked because they get upgraded together.

This is also true of Extreme Networks switches.

I have have N3000 stack too. If I connect 1 * 10 GbE from the N4000 stack to 1 * 10 GbE on the N3000 stack, and set the interfaces to allow vLAN1 and vLAN20, on both stacks, will anything on each vLAN route though the 10 GbE to the other stacks respective vLAN? I guess like a dumb layer 2 switch being connected to another dumb switch, they just pass traffic irrespective of vLAN?

It should.

@Jimmy9008
It does if they are the same type of port (general or trunk).

But it would better to use use two 10G links and bond them with LACP active on both switch stacks.
