Trunk 4K VLANs on an Interface

I have an ICX 6430-24P. I want to trunk as many VLANs as possible on two interfaces. This seems to be something switch manufacturers like to make painful.

 

What I have tried:

  • First, I increased the max vlans system value to 4095 and restarted the system.
  • Then, I entered the following:
    • ICX6430-24P Switch(config)#vlan 2 to 4094
    • ERROR-can't have more than 64 vlans at a time in a multi-range vlan command
  • Ok, so try port group:
    • ICX6430-24P Switch(config)#vlan-group 1 vlan 2 to 4000
    • VLAN group 1 is too big. Only 256 vlans are allowed at a time

So, do I have to just make 16 port groups and then tag the interfaces on each of the 16 port groups? I hope not.

 

I like the Cisco paradigm of going to the interface and just making it a trunk and permitting all. Then it is a pretty simple TCL script to make all of the VLANs (In 3com/comware/h3c/huawei world it is even easier, "vlan batch 2 to 4094"). I wish that was available here, because VLANs really are properties of ports, not the other way around as ProCurve and Brocade want you to think.

 

Thanks,

Re: Trunk 4K VLANs on an Interface

Hi Gns,

 

I have found these two references

http://www.brocade.com/content/html/en/configuration-guide/fastiron-08030d-l2guide/GUID-DCD97A06-1F15-435B-AC21-DA021DED82F3.html

These confirm what you have already tested

 

With the VLAN group command you can add up to 256 VLANs with the command at one time.

When configuring a VLAN range the maximum number of VLANs you can create or configure with a single command is 64.

 

The links above show the correct way to configure more using multiple commands

Mick
