Switching

I need to configure 2 pools for diferent vlans, that is possible?

EXAMPLE

EX assing ip address for two different vlans

vlan voice pool 192.168.1.0/24

vlan data pool 172.16.1.0/24

thanks

Yes, you can configure separate pools for the two vlans.  You simply use the network segment that matches your layer 3 vlan as the dhcp pool name to tie them together.

The procedure is outlined in KB11018 with a set of sample configuration commands for setting up the pool.

interface VLAN 20 has IP 20.20.20.1/24

pool 20.20.20.0/24 {
    address-range low 20.20.20.50 high 20.20.20.100;
    default-lease-time 3600;
    name-server {
        20.20.20.1;
    }
    wins-server {
        20.20.20.1;
    }
    router {
        20.20.20.1;
    }
    server-identifier 20.20.20.1;
}
