Configuring
Automatic One of the most important considerations in automatic VLAN
Configuration of configuration is network security. Network administrators must have VLANs and Network complete control over how known users access and use the network. In
Security addition to this, administrators must also have complete control over who accesses the network and the times and locations where the network was accessed from. Network intrusions must be detectable and dealt with automatically.
When devices are setup for auto configuration based on a policy, all unused ports, or ports whose link status is down, are automatically placed in the default VLAN. The ports are moved out of the default VLAN only when a recognized endstation or user connects to a port. This ensures that unknown users do not have access to all VLANs in the network. The default VLAN can be secured by not enabling any network services within this VLAN, as well as not as connecting the default VLAN to the rest of the routed network.
VLAN Server and The VLAN server is a parameter database or repository that holds the Automatic VLAN VLAN mapping information. The VLAN Server is an important component
Configuration of the VLAN
There are two types of VLAN servers currently implemented:
1
2Integrated TEM/Unix or TEM/NT based VLAN server.
Stand-alone NT based VLAN Server.
This server is used by SuperStack II Switch1000/3000 and Desktop switches when configured in AutoSelect Mode, to execute automatic VLAN configuration based on MAC addresses. See the description of AutoSelect Mode VLAN configuration.
