Above figures for connection between Two different product Cisco and Extreme. We just consider Cisco as Core Layer and Exreme as Access Layer switch to work in VoIP World.
There are 2 switches implemented called cisco catalyst 3560 and extreme x250e-48p.
One dhcp server on Fa0/1 port of Cisco switch will distribute vlan called Data vlan 10,20 and Voice vlan 110,120 via trunk link.
Management vlan 100 also configured on both switch for using telnet remote management.
| Vlan Name | Vlan IP Assignment |
| Vlan 10 | 10.10.1.1/24 |
| Vlan 20 | 10.10.2.1/24 |
| Vlan 110 | 192.168.10.1/24 |
| Vlan 120 | 192.168.20.1/24 |
| Vlan 130(Server) | 172.16.172.27/24 |
