I need advice.
At my former office, we used to have another vlan e.g. vlan 10 for management vlan purpose so that we do not use default VLAN 1 to access the switches which i think is good for security purpose.
Now how can I convince my present company that it is the best way to go as they have only vlan 1 for management purposes but then use another vlan say vlan 189 for all unused port which alas, they do not keep to, so invariably, we have ports in vlan 1 and 99 and every where
Is there a doc whereby I can show them why it is best to have a different management vlan from default vlan.?
