VLAN TRunk betwen M4300 Stack and M4100-26G

[gdelong]

I am trying to build a VLAN trunk between a new M4300 switch stack and a M4100-26G

I can get default Vlan to pass traffic but nothing else

There is now inter vlan routing configured

The vlans are working correctly inside the stack

I have tried setting the vlan trunking configuration to both trunk and general on both switchs

Until upgrading my M4100 Stack to the new M4300 I had no problems

I appear to be missing soemthing fundemental in the way the trunking is handled in the M4300

I have broken it down to just the default Vlan 1 and Vlan 401 and and can not get that simple configuration to work.

Hi gdelong,

Welcome to the community!

Do you mean when config VLAN trunking allowed VLAN ID list on switch, the traffic that tagged with allowed VLAN ID cannot forwarding between these two Switches?

Could you please kindly answer the questions for VLAN trunking configuraiton as below?

For M4300 and M4100:

1. What is the 'Switchport Mode' on VLAN Trunking Configuration page?

2. What is the 'Native VLAN ID' for the port?

3. What is the 'Trunk Allowed VLANs' for the port?

4. It would be help if you can tell us your test topo.

Could you please kindly answer the questions for VLAN trunking configuraiton as below?

For M4300 and M4100:

1. What is the 'Switchport Mode' on VLAN Trunking Configuration page? I have tried both Trunk and General, matching the ports on both switches for each try.

2. What is the 'Native VLAN ID' for the port? 1

3. What is the 'Trunk Allowed VLANs' for the port? I have tried 1,401 and the defaul 1-4093

4. It would be help if you can tell us your test topo. I have a 4 unit M4300 2x 52G, 1 X 26g and 1 X 26g poe+ Stack with 6 VLAN and use VLAN 1 as the defualt. I have multiple remote M4100 switches in IDFs. Right now just to try and  get it working I am simply trying to pass VLAN 401 and 1. If I assign PVID 401 and VLAN 401 to a port it works as expected on the M4300 Stack.

Is it possible to just tell me how to properly configure a port on the M4300 and the M4100 to pas Vlan 1 the default and Vlan 401?

Hi dgelong,

Below is the answer for your question, hope it can helps!

Is it possible to just tell me how to properly configure a port on the M4300 and the M4100 to pas Vlan 1 the default and Vlan 401?

For example: PC1 communicate with PC3 on VLAN1, PC2 communicate with PC4 on VLAN401

PC1/2-----(port1/2)M4100(port3)------(port3)M4300(port1/2)------PC3/4

Below is the configuration:

On M4100&M4300:

Port1: General mode, PVID=1, untag join to VLAN1 member(just default config)

Port2: General mode, PVID=401, untag join to VLAN401 member

Port3: General mode, PVID=1, untag join to VLAN1 member, tag join to VLAN401 member

So as in my case that does not work what is the first couple of things to look at?

It is configured the way you say

Vlan 1 (untagged) works on remote switch and Vlan 401(tagged) does not

Hi gdelong,

Could you please provide the configuration file of the two Switches, we can analysis further more.

How do I send configure files from my Managed Switch to NETGEAR community moderators?

Hi gdelong,

We have got your configuration file for two Switches. Thanks again!

Looks like there is no any problem for the configuration.

It's will be better if you could tell us the VLAN 401 traffic topo. from/to which port on M4100 and M4300?
