Hi,

I think to support extended range of vlans the device should be in vtp transparent mode and in addition make sure the vlan is created first in the vtp database.

Thanks

Hi

When You use extended range, the switch starts to reserv vlans, usualy from 1006 and upwards.

To see what is already reserved use the command

"show vlan internal usage"

Now You know what vlans You can use.

I can see that this vlan is used for internal purpse. Is there is anyway to free up this vlan ?.my dsp asked to configure this vlan on my interface.

Hi

I'm not aware of any command that can free the vlan.

Maybe the description of the vlan in the command "show vlan intern usa" can give You a clue, and remove whatever is occupied the vlan.

A more burly way to do it is,

do a copy run to tftp

edit the file with the command you want, like this

interface GigabitEthernet6/1.1025
encapsulation dot1Q 1025

do not edit anything else

then copy tftp to start

reload
