original state.
Protocol VLANs do not create new VLAN, but share with port-based VLANs. Once
the packets enter these VLANs, they will be transmitted according to the same rules as
port-based VLANs use.
Classified by network layer protocols, different protocols can belongs to different
VLANs. This is very attractive for those networks hoping to organize users aiming at
specific applications and services. Beside, users can move as they will within the network
while keeping their VLAN membership unchanged. The advantage of this method is that,
the physical location of users can change without reconfiguring the VLAN they belong to.
And it is also very significant for the network managers that the VLAN can be classified by
protocol type. What's more, this method does not need additional frame tag to identify
VLANs, and thus can decrease the communication traffic of the network.
In DCS-3950 series, 1000bps network ports can support Protocol VLAN fucntion
unconditionally, while the 100bps Ethernet ports have to be set to trunk ports to use the
function.
