4506 vlan split

I have 4506 switch with two ip addresses on default vlan, primary and secundary, different C classes. I want to split this on two vlans. Can I make second vlan and move one IP address to this vlan and then configure bridge between thost two vlans and then slowly move client PCs ports to second vlan? What would configuration looks like? Just put bridge-group 1 command onto these two VLANs?

Thanks!

Re: 4506 vlan split

You can change all the client ports at one go, using interface range command.

int vlan 1

ip add y.y.y.y <--- current primary ip

int vlan 2

no shut

ip add <--- move the secondary ip here.

vlan 2

name Secondary vlan

interface range fa 1/24 - 48

switchport mode access

switchport access vlan 2

spanning-tree portfast

Approx downtime would be approx 1 minute (even less depending upon how fast you cut and paste).

Re: 4506 vlan split

:-)) clients are spreded across 19 access switches. If I could do this using bridge I can move them during working hours
