Hi,
As we are having some perfomance problems when logging into the network i'm doubting about my switch config.
What i did is :
Changed native vlans on the trunks to vlan 900
configured layer 2 and layer 3 vlan 900
did a shutdown for vlan 1
Is there still traffic going into vlan 1 even if you changed native vlan to another 1.
Did i forget some commands?
Best regards
Jorg

Jorg,
You have all the control traffic like CDP,VTP,Pagp that always uses Vlan 1 to travel across the turnk links. Its always advisable to use a separate management vlan or probably a different native vlan but Vlan 1 will always carry the above listed control traffic.
