Thanks for the extra info. After doing some research it turns out you cannot make an existing VLAN into the default VLAN. So we need to run these commands, and it should work. #no int vlan 11 #default vlan-id 11 Keep us posted
Hi, I am trying to change the default vlan1 to 11 , since i need to work with vlan 1 and to tagged interface in it when i am executing the command below i get  SRV-FCSW-CORE1(conf)#default vlan-id 11 % Error: Existing VLAN cannot be set to default VLAN Vl 11. Any idea how to get this? Please advice  Thanks
