Say I have 7000+ switches that I want to add a new SVI to:

int vlan 222

ip address 10.xxx.yyy.254

And I want xxx.yyy to be unique to each switch. Is there a way to:

a) specifiy what xxx.yyy should be for each device?

b) query that information from the device first, and then use that information in the variable?

Using automated scripts or any other way to do this automagically?

Thanks
