Native Vlan and Trunking

mohindersingh · ‎10-30-2007

Hi Folks,

I am having a doubt with native Vlan in trunk ports.

In a topology of 3 switches. Switch A is connected with switchB and SwitchC on uplinks. Can I configure the different native vlans for 2 different trunk for switch A.

Like I am having 3 vlan,s configured in switch A with VTP domain transparent(1,500,900-Vlans configured). Same configuration is there in B & C too.

So can we use 999 as a native vlan for trunk between A&B and native vlan 1 for trunk configured between A&C.

Yup, you're right. Just being curious, why do you want to use different native vlans on each uplink?

yes possible, if specific reasons. Already discussed several times on this forum. Pls refer this link:
