Auto config of VLANs on 6860

[mouthpiec]

Hi,
Just got two 6860 routers, and by default these create vlans in the range of 4xxx.
Is there a way to disable these automated vlans?

thanks in advance

You can disable the auto-fabric funktion. This function enables a lot of auto-*** things. F.e. MVRP and SPB. And the 4xxx vlans are the backbone vlans for SPB.
Use the following command - within R8.4 all the automaticly created functions/setting are disable with this:

Code: Select all

auto-fabric admin-state disable remove-global-config

thanks silvio, i tried your command but VLAN 4094 was still created ... I need to check also what will happen when I add linkagg interfaces.

Code: Select all

-> show vlan
 vlan    type   admin   oper    ip    mtu          name
------+-------+-------+------+------+------+------------------
1      std       Dis     Dis   Dis    1500    VLAN 1
111    std       Ena     Ena   Ena    1500    TEMP OAM
122    std       Ena     Ena   Ena    1500    INTRA_CORE
4094   vcm       Ena     Dis   Dis    1500    VCM IPC

4096 is always there. It is necessary for IPC (interprocess communication) between the virtual chassis members. You have to avoid to use this vlan.

Ok thanks. Tomorrow will continue to make some sample config before putting it live. Thanks for your help.

Using the suggested disable command, will I need to crear tele stp commands manually?

hi again Silvio,
on a post on this forum, it was suggested to perform thew following commands ... are these are required?

auto-fabric admin-state disable remove-global-config
mvrp disable
spb isis admin-state disable
no spb bvlan 4000-4015
spantree mode per-vlan

[silvio]

in older releases all of them where necessary. This commands where my advice for a long time. But since half a year or so the first command make all of them in one.
But there is no problem to use all of them.
Also you should always check the success of your commands. F.e. if you wish the per-vlan-stp mode (1x1 in R6) than you should check this.
(show spantree cist, show spb config, show vlan, show mvrp config or similar....)
regards
Silvio
