Ada 2 buah switch yang berbeda brand, yaitu CISCO C2960 dan Alcatel-Lucent OmniSwitch 6450 akan dihubungkan dengan melewatkan  VLAN.

VLAN = 212
Cisco C2960  = port 0/47
Alcatel 6450 =port 1/1

  1. Login ke Cisco C2960
  2. Konfigure port 0/47 untuk VLAN 212, seperti langkah dibawah :

  CISCO C2960

2960-A5#conf t
Enter configuration commands, one per line. End with CNTL/Z.
2960-A5(config)#int
2960-A5(config)#interface fas 0/47
2960-A5(config-if)#description "Interconnection to Alcatel Switch"
2960-A5(config-if)#switchport access vlan 212
2960-A5(config-if)#switchport trunk native vlan 212
2960-A5(config-if)#switchport mode trunk
2960-A5(config-if)#spanning-tree bpdufilter enable  // ==> STP di-disable untuk interkoneksi
2960-A5(config-if)#do sh run interface fa0/47

interface FastEthernet0/47
description "Interconnection to Alcatel Switch"
switchport access vlan 212
switchport trunk native vlan 212
switchport mode trunk
spanning-tree bpdufilter enable
end
2960-A5#write memory
2960-A5#copy running-config startup-config

 

  1. Kita beralih ke switch Alcatel-Lucent OmniSwitch 6450
  2. Konfigure port 1/1 untuk VLAN 212, seperti dibawah ini.

catatan penting:
Untuk masing-masing switch, STP harus didisable pada port interface yang akan digunakan interkoneksi
