VLAN question

anitachoi3 · ‎02-22-2008

Hi,

I setup two ethernet switches (CAT 3750) on 8/F and 32/F. detail please check the attached file.

there are two fibers to be connected to each other. It has two VLANs on 8/F and 32/F. 192.168.12.0/24 and 192.168.24.0/24. how do I config the CAT to force the 192.168.12.0/24 traffic to fiber A and 192.168.24.0/24 go fiber B?

any suggestion?

If you are only going to deal with 2 Vlans, let's call 192.168.12.0/24 Vlan12 and 192.168.24.0/24 Vlan24.

Then on the switches, where you want traffic for Vlan12 to go just issue the following on the switchports

interface fx/x

switchport mode access

switchport access vlan 12

On the switchport where you want Vlan24 just issue:

interface fx/x

switchport mode access

switchport access vlan 24

If you wanted to trunk the ports, issue the following:

interface fx/x

switch port trunk encapsulation dot1q

switchport mode trunk

switchport trunk allowed vlan 12

For Vlan12 and for Vlan24

interface fx/x

switch port trunk encapsulation dot1q

switchport mode trunk

switchport trunk allowed vlan 24

One thing to keep in mind, I recommend going with the trunk if you plan on carrying more than one Vlan over that link. If you aren't then go with the access-vlan method.

HTH,
