Boleh buat TAG kat port 34 tu.. Port 50 kat switch B boleh set access vlan x utk semua member switch A as member vlan X dan user dalam switch B default vlan = 1

Buat TAG kat port 50 tu pun boleh jugak tapi kena set access port x kat switch A

Firewall kena support tag jugak.

biasa aku buat trunk port permit vlan all je

 

ada vlan ke?

 

contoh kalo HP

 

 

 

 

interface GigabitEthernet1/1/1
 port link-mode bridge
 description xxxxx
 port link-type trunk
 port trunk permit vlan all

 

 

kalo cisco

 

 

 

 

interface GigabitEthernet1/0/28
 switchport mode trunk

 

 

dua2 kena port trunk...

Tak faham sangat soalan. Boleh jelaskan lagi?

 

Ada 2 jenis port je dalam Cisco switch.

 

1. Access port

2. Trunk port

 

Penjelasan

1. Access port boleh bawak 1 VLAN traffic sahaja

2. Trunk port secara default dia boleh bawak semua VLAN antara switches. Sebab tu ada special tags untuk membezakan aliran traffic samada dari VLAN X atau VLAN Y dsb.

 

Klu ikut diagram ni memang kena buat trunk antara switch. Kena configure 2 2 switch dengan mekanisma yang sama.

 

Klu Cisco switch boleh pilih samada guna ISL atau 802.1Q je

Switch#conf t

Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#int f0/1

Switch(config-if)#switchport ?

access Set access mode characteristics of the interface
mode Set trunking mode of the interface
native Set trunking native characteristics when interface is in
trunking mode
nonegotiate Device will not engage in negotiation protocol on this
interface
port-security Security related command
priority Set appliance 802.1p priority
trunk Set trunking characteristics of the interface
voice Voice appliance attributes
<cr>
Switch(config-if)#

 

Switch(config-if)#switchport access ?

vlan Set VLAN when interface is in access mode

Switch(config-if)#switchport access

 

Switch(config-if)#switchport trunk ?

allowed Set allowed VLAN characteristics when interface is in trunking
mode
encapsulation Set trunking encapsulation when interface is in trunking mode
native Set trunking native characteristics when interface is in
trunking mode
Switch(config-if)#switchport trunk
