VLAN Configuration on Cisco Switch [IOS]
Bismillah, kembali lagi teman-teman disini saya akan melanjutkan lesson yang sebelumnya https://torkisnetwork.blogspot.com/2021/03/introduction-to-vlans.html Insyaa Allah di blog ini akan rutin kita menulis satu persatu materi cisco level professional, kita sudah mengenal apa itu VLAN dan apa fungsinya. Hari ini kita akan mempraktikkan dan list step yang akan kita lakukan
- Konfigurasi IP Address
- Create VLAN
- Switchport Access VLAN
- verifikasi
pada Lab kali ini saya menggunakan GNS3 (like a real device), jika teman-teman mau menggunakan PT (Packet Tracer) silahkan tidak masalah. Perhatikan topology dibawah ini saya menggunakan 3 PC sudah cukup dan 1 Switch Cisco :
Topology VLANs
1. Konfigurasi IP Address pada : PC1, PC2 dan PC3
PC1> ip 10.10.10.1 255.255.255.0
Checking for duplicate address...
PC1 : 10.10.10.1 255.255.255.0
PC2> ip 10.10.10.2 255.255.255.0
Checking for duplicate address...
PC1 : 10.10.10.2 255.255.255.0
PC3> ip 192.168.10.10 255.255.255.0
Checking for duplicate address...
PC1 : 192.168.10.10 255.255.255.0
2. Create VLAN pada Switch and Switch mode access :
"vlan 10" dan "vlan 20" adalah command untuk mengcreate vlan pada switch, kemudian "show vlan brief" command untuk memverifikasi apakah vlan sudah created atau belum,
Switch(config)#vlan 10
Switch(config-vlan)#exit
Switch(config)#vlan 20
Switch(config-vlan)#exit
Switch(config)#exit
Switch#show
*Mar 16 06:56:00.445: %SYS-5-CONFIG_I: Configured from console by console
Switch#show vlan brief
VLAN Name Status Ports
---- -------------------------------- --------- -------------------------------
1 default active Et0/0, Et0/1, Et0/2, Et0/3
Et1/0, Et1/1, Et1/2, Et1/3
Et2/0, Et2/1, Et2/2, Et2/3
Et3/0, Et3/1, Et3/2, Et3/3
10 VLAN0010 active
20 VLAN0020 active
1002 fddi-default act/unsup
1003 token-ring-default act/unsup
1004 fddinet-default act/unsup
1005 trnet-default act/unsup
Switch#
perhatikan teman-teman di command "show vlan brief" interface e0/0 dan inteface e0/1 blum kita masukkan ke grup vlan 10 dan e0/3 blum kita masukkan ke grup vlan 20 masih default di vlan 1, berikut dibawah command untuk memasukkan interface ke grup tertentu "switchport mode access [vlan name]", berikut :
Switch(config)#interface ethernet0/0
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 10
Switch(config-if)#exit
Switch(config)#int e0/1
Switch(config-if)#sw mod acc
Switch(config-if)#sw acc vlan 10
Switch(config-if)#exit
Switch(config)#int e0/2
Switch(config-if)#sw
Switch(config-if)#switchport mod acc
Switch(config-if)#sw acc vlan 20
Switch(config-if)#
kemudian kita mulai verifikasi apakah sudah berhasil menginputkan interface ke dalam vlan tertentu, dengan command "show vlan brief",
Switch#show vlan brief
VLAN Name Status Ports
---- -------------------------------- --------- -------------------------------
1 default active Et0/2, Et1/0, Et1/1, Et1/2
Et1/3, Et2/0, Et2/1, Et2/2
Et2/3, Et3/0, Et3/1, Et3/2
Et3/3
10 VLAN0010 active Et0/0, Et0/1
20 VLAN0020 active Et0/2
30 VLAN0030 active
1002 fddi-default act/unsup
1003 token-ring-default act/unsup
1004 fddinet-default act/unsup
1005 trnet-default act/unsup
Switch#
3. Verifikasi ping, show interface [name interface] dan show vlan brief:
ping PC1 ke PC2
PC1> ping 10.10.10.2
84 bytes from 10.10.10.2 icmp_seq=1 ttl=64 time=4.659 ms
84 bytes from 10.10.10.2 icmp_seq=2 ttl=64 time=4.273 ms
84 bytes from 10.10.10.2 icmp_seq=3 ttl=64 time=4.030 ms
84 bytes from 10.10.10.2 icmp_seq=4 ttl=64 time=2.414 ms
84 bytes from 10.10.10.2 icmp_seq=5 ttl=64 time=4.280 ms
ping beda VLAN PC1 (VLAN 10) and PC3 (VLAN 30)
PC1> ping 192.168.10.10
host (255.255.255.0) not reachable
Untuk ping beda vlan akan terjadi fail karna beda vlan, untuk case ini kita butuh router atau L3 Switch untuk melakukan routing/ encapsulation antar switch untuk bagian menghubungkan antar vlan kita akan bahas pada blog yang lain.
