changing native vlan

Is there a good reason to change the default native vlan 1 between two 802.1Q trunks? And is there a rule regarding best practices? thanks.

Re: changing native vlan

With 802.1q trunking, the only significance of the native vlan is the fact that it is not tagged. Most administrators default to vlan 1, but others vary.

It's discussed in the best practices document, but there's no specific best practice for Native Vlan, as changing it does not have any bearing on network performance or stability. It does talk about the significance of Vlan 1, which may be of interest.
