Konfigurasi PSVT+

SKEMA JARINGAN

Buatlah VLAN 10, 20, 30, 40, 50, 60, 70, 80 dan 99 pada semua switch. Sebagai contoh seperti konfigurasi pada Switch 1

S1(config)# vlan 10

S1(config-vlan)# vlan 20

S1(config-vlan)# vlan 30

S1(config-vlan)# vlan 40

S1(config-vlan)# vlan 50

S1(config-vlan)# vlan 60

S1(config-vlan)# vlan 70

S1(config-vlan)# vlan 80

S1(config-vlan)# vlan 99

Konfigurasikan pada semua switch seperti contoh

Mengaktifkan mode access pada S1, S2, S3 dan mendaftarkan access vlan-vlan yang telah di tentukan

S1(config)# interface f0/6

S1(config-if)# switchport mode access

S1(config-if)# switchport access vlan 30

S1(config-if)# no shutdown

S2(config)# interface f0/18

S2(config-if)# switchport mode access

S2(config-if)# switchport access vlan 20

S2(config-if)# no shutdown

S3(config)# interface f0/11

S3(config-if)# switchport mode access

S3(config-if)# switchport access vlan 10

S3(config-if)# no shutdown

 

Mengaktifkan mode trunk native VLAN 99 pada S1, S2, S3

S1(config)# interface range f0/1-4

S1(config-if-range)# switchport mode trunk

S1(config-if-range)# switchport trunk native vlan 99

S2(config)# interface range f0/1-4

S2(config-if-range)# switchport mode trunk

S2(config-if-range)# switchport trunk native vlan 99

S3(config)# interface range f0/1-4

S3(config-if-range)# switchport mode trunk

S3(config-if-range)# switchport trunk native vlan 99

Berikan IP Address terhadap VLAN 99 Pada S1, S2, S3

S1(config)# interface vlan99

S1(config-if)# ip address 172.31.99.1 255.255.255.0

S2(config)# interface vlan99

S2(config-if)# ip address 172.31.99.2 255.255.255.0

S3(config)# interface vlan99

S3(config-if)# ip address 172.31.99.3 255.255.255

Konfigurasikan STP dan PVST+ Load Balancing, S1 prioritas VLAN 1, 10, 30, 50, 70. S2 secondary untuk semua VLAN. S3 prioritas VLAN 20, 40, 60, 80 dan 99.

S1(config)# spanning-tree mode pvst

S1(config)# spanning-tree vlan 1, 10, 30, 50, 70 root primary

S2(config)# spanning-tree mode pvst

S2(config)# spanning-tree vlan 1, 10, 20, 30, 40, 50, 60, 70, 80, 99 root primary

S3(config)# spanning-tree mode pvst

S3(config)# spanning-tree vlan 20, 40, 60, 80 root primary

Konfigurasikan Portfast dan BPDU Guard

S1(config) interface f0/6

S1(config) spanning-tree portfasr

S1(config)# spanning-tree bpduguard enable

S2(config) interface f0/18

S2(config) spanning-tree portfasr

S2(config)# spanning-tree bpduguard enable

S3(config) interface f0/11

S3(config) spanning-tree portfasr

S3(config)# spanning-tree bpduguard enable

 

Konfigurasikan ip address pada pc

PC 1

Subnetmask : 255.255.0.0

PC 2

Ip address :172.31.10.22

Subnetmask : 255.255.0.0

PC 3

Ip address: 172.31.10.23
