Task Extreme?
Create a loopback Interface?
interface loopback 1
IP address 192.168.1.1 255.255.255.0
Create Interface vlan 101
IP address (loopback 1)
Interface vlan 102
IP address (loopback 1)
Interface vlan 103
IP address (loopback 1)
Example Cisco:
interface loopback 1
IP address 192.168.1.1 255.255.255.0
interface vlan 101
IP unnumbered loopback 1
Interface vlan 102
IP unnumbered loopback 1
Interface vlan 103
IP unnumbered loopback 1

IP unnumbered can be done via Super-Vlan in ExtremeXOS.

Igor,
That's not possible. DHCP server only serves the vlan it belongs to. And each vlan has to have its own IP address.

DHCP
server dhcp-pull 192.168.1.0/24 vlan 102
server dhcp-pull 192.168.2.0/24 vlan 103
vlan-102 120 subscribers
vlan-103 250 subscribers
I want to make
server dhcp-pull 192.168.1.0/23 vlan 101
create vlan "vlan101"
enable loopback-mode vlan vlan101
configure vlan vlan101 ipaddress 192.168.1.1 255.255.254.0
enable ipforwarding vlan vlan101
create vlan "vlan102"
configure vlan vlan102 tag 102
#use the ip address vlan 101
#cisco: ip unnumbered
create vlan "vlan103"
configure vlan vlan103 tag 103
#use the ip address vlan 101
#cisco: ip unnumbered

Igor,
Each vlan has to have its own ip address. If you want to have a loopback address for the whole switch then:
Each vlan has to have its own ip address. If you want to have a loopback address for the whole switch then:
- Select one of the vlans in the switch and enable loopback-mode
- assign loopback ip address
- assign ip addresses to all other vlans
- enable ipforwarding in all vlans
