I have several vlans on 2950 switches. Each vlan is monitered seperatly and the data on the vlans must never mix. Should I move the native vlan off vlan 1 and set it to match the individual vlan numbers? Or maby I just don't understand the function of the native vlan.
The native vlan is the vlan on an 802.1q trunk that isn't tagged with an 802.1q header. And that's all there really is to it.
Generally, most administrators use the same native vlan for the sake of consistency. Some tag the management vlan as the native vlan, while others will set an unused vlan as the native vlan. It's mostly a matter of procedure, policy, and personal preference.
My main concern is data crossing from one vlan to another. If vlan 1 goes everywhere by default
how can I be positive nothing will cross on vlan 1. I believe I read that untagged packets will be sent on vlan 1. I really need x number of seperate networks sharing a switch, but they must be absoutly seperate. I'm not parinoid but my boss is.
