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?

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

Hi, the command "auto-fabric admin-state disable" did the job
