VOSS - Can't add multiple VLANs to a port or VLANs to an MLT or port from VLAN!?

Anonymous — Thu, 09 Jul 2020 02:21:52 GMT

Hi,

Appreciate this could be a straight forward question, its for a VSP8600 version 6.3.2.0.

The system has been configured using the simplified vist (it was requested)

As part of the configuration I need to add VLANs to MLT interfaces like so:

mlt 55 vlan 50,52,56,70,101,109,223,510-511,514,562,580,666,669,723,787

Issue I have is that it wont let me add this unless I disable LACP on the MLT interface first, so to add the VLANs I would need to do the following:

interface mlt 55
no lacp enable
mlt 55 encap dot1q
mlt 55 vlan 50,52,56,70,101,109,223,510-511,514,562,580,666,669,723,787
interface mlt 55
lacp enable
exit

This is odd to me, as what happens if this was a working MLT, doesn’t make sense to have to disable LACP just to add more VLANs to it?.

Additionally there seems to be a way to add multiple ports to a VLAN but not multiple VLANs to a port

As an example you can execute the following:

vlan members 2 2/23-2/24,3/24,4/23-4/24,5/24,6/23-6/24 portmember

but I can’t do the this, it will only except one VLAN at a time!?

vlan member add 50,52,54,56,101,107,109,510-511,562,580,775,787,794-795,900-901 2/1

I need to add multiple VLANs to the port because it is a core switch where every port has multiple VLANs and I have a lot to do, so I couldn't’t really do it in reverse!?

Another issue is If I try and use the EDM as per below to remove a port from a VLAN I get the following error:

Sure there is a perfect explanation just seems odd on the surface.

Many thanks in advance

Hi Martin, when the LAG is configured as LACP and it is operationally UP in order to add a VLAN try using the following syntax:

vlan mlt <vlan id> <mlt id>

I don’t think that you can add multiple VLANs in one step.

Just curious what type of switches are connected to those ports?

Dinesh_Rego — Thu, 09 Jul 2020 02:37:41 GMT

Have you tried using “mlt <id> vlan <vids” instead of “vlan mlt <vid> <mlt-id>” when adding VLANs to LACP enabled MLT?

Hi Roger / Dinesh,

Thanks for both answering, let me try those commands and get back to you.

In regards to the switches they are EOS B and C-Series switches connecting to the ports.

Get back shortly

Thanks,

As a rule traditional LACP is not dynamic. So you must disable the LACP to perform and config Moves, Add, and Changes. So that is normal behavior.

That was the beauty of MLT was that it was a Dynamic LAG. That is why you should always use MLT first and only LACP when you absolutly have to. If its an NORTEL, AVAYA or Extreme ERS on the other end of the connections always just use MLT.

As for adding VLANs, I always use the VLAN MEMBER ADD (Vlan ID) <Ports> command.

Or the VLAN MLT XX XX command. (forget the exact syntax)

Roger_Gravelle — Thu, 09 Jul 2020 03:07:52 GMT

Regarding the edge switches I was hoping that you had something that supported Fabric Attach such as EXOS or ERS. That would make it much easier for you. Unfortunately EOS does not have FA.

There was a time where you had to disable the LACP LAG to add VLANs but that was changed several years back (for good reason). You should be able to do so using the above commands. Note that when you save to config you will see the ports in a ‘vlan member add’ command. Also note that if you have any ports that are members of the LACP LAG but not up you may need to add them manually while down - they must match in order to be dynamically added to the LAG when they come up.

Thanks all for posting back.

Unfortunately I looked at those commands and I’m still stuck with the same problems:

Think I remember you can add VLANs to MLT with LACP if the port is up, still odd way of working though?
Your not able to add multiple VLANs to a port, this is a big problem!?
Unable to remove a port from a VLAN, again,, very odd but its probably because something else is configured that is stopping it?

The second point is very important has there are 100’s of ports all with multiple different VLANs on each, say something like the following:

vlan member add 50,52,54,56,101,107,109,510-511,562,580,775,787,794-795,900-901,4090 2/1
vlan member add 50,52,56,70,101,109,226,510-511,514,560,562,570,580,666,669,726,787 2/2
vlan member add 50,52,56,70,101,109,226,510-511,514,580,666,669,726,757,787 2/3
vlan member add 50,52,56,70,101,247,510-511,752 2/4
vlan member add 5,50,52,56,101,109,126,224,510-511,514 2/5
vlan member add 25,28,50,52,56,83,101,244,510,744 2/6
vlan member add 50,52,200-201,763 2/7
vlan member add 50,52,56,101,123,260,511,900,4090 2/8
vlan member add 50,52,56,70,101,109,208,500,510,511,514,580,666,669,708,771,787 2/9
vlan member add 50,52,56,70,101,109,238,510,511,514,580,666,669,738,787 2/10
vlan member add 25,50,52,56,70,101,109,209,254,500,510,511,514,562,580,666,669,709,771,776,781,787 2/11
vlan member add 50,52,56,70,101,109,249,500,510511,514,562,580,666,669,749,776,781,787 2/12
vlan member add 50,52,56,70,101,109,250,510-511,514,562,580,666,669,750,776,781,787 2/13
vlan member add 50,52,56,70,101,109,151,50,52,56,70,101,109,250,510-511,514,562,580,666,669,750,776,781,787200-201,510-511,514,580,666,669,787 2/14
vlan member add 1,27,50,52,54,56,70,101-102,109,221,227,248,510-511,514,580,666,669,712,721,727,748,764,787 2/15

To go through every line and add each VLAN to the port one at a time would take a crazy long time, just wouldn’t be efficient.

I’m basically replacing an existing network like for like with a VSP, hence the configuration being the way it is. Unfortunately do some simple configuration is becoming challenge.

Appreciate if there is a way around it?

Many thanks

I’m with you on adding multiple vlans to a port, very frustrating to have to do it one at a time. Then there is 3 lines for dhcp relay for every interface per every device you want to do dhcp relay for i.e. dhcp, nac etc. Those are fun.

Since I already sold you my ACLI terminal in another post…

http://www.oranda.fr/ACLI-terminal/

With it, you can do the following..

Create VLANs:

VSP8600-1:1(config)#% vlan create %s type port 0 &'10-20,25
VSP8600-1:1(config)#% vlan create 10 type port 0
VSP8600-1:1(config)#% vlan create 11 type port 0
VSP8600-1:1(config)#% vlan create 12 type port 0
VSP8600-1:1(config)#% vlan create 13 type port 0
VSP8600-1:1(config)#% vlan create 14 type port 0
VSP8600-1:1(config)#% vlan create 15 type port 0
VSP8600-1:1(config)#% vlan create 16 type port 0
VSP8600-1:1(config)#% vlan create 17 type port 0
VSP8600-1:1(config)#% vlan create 18 type port 0
VSP8600-1:1(config)#% vlan create 19 type port 0
VSP8600-1:1(config)#% vlan create 20 type port 0
VSP8600-1:1(config)#% vlan create 25 type port 0
VSP8600-1:1(config)#%

I only typed the 1st command, the rest is done by the terminal..

And then to assign them all to a port:

VSP8600-1:1(config)#% vlan members add %s 2/4 &'10-20,25
VSP8600-1:1(config)#% vlan members add 10 2/4
VSP8600-1:1(config)#% vlan members add 11 2/4
VSP8600-1:1(config)#% vlan members add 12 2/4
VSP8600-1:1(config)#% vlan members add 13 2/4
VSP8600-1:1(config)#% vlan members add 14 2/4
VSP8600-1:1(config)#% vlan members add 15 2/4
VSP8600-1:1(config)#% vlan members add 16 2/4
VSP8600-1:1(config)#% vlan members add 17 2/4
VSP8600-1:1(config)#% vlan members add 18 2/4
VSP8600-1:1(config)#% vlan members add 19 2/4
VSP8600-1:1(config)#% vlan members add 20 2/4
VSP8600-1:1(config)#% vlan members add 25 2/4
VSP8600-1:1(config)#%
VSP8600-1:1(config)#% vlni 2/4
               alias% show interfaces gigabitEthernet vlan 2/4
====================================================================================================
                                   Port Vlans
====================================================================================================
PORT             DISCARD DISCARD   DEFAULT VLAN         PORT     UNTAG    DYNAMIC UNTAG

----------------------------------------------------------------------------------------------------

Again, I only typed the 1st command, and then the vlni 2/4 one.

What can I say, that application is awesome, completely flips the use of the cli into something that makes it usable.

I would even go as far as saying it is a must have requirement.

Thank you for creating and sharing it, really is going to make things very much easier for me.

Cheers,

Martin
