What is VLAN Manager?
VLAN Manager enables you to manage VLAN and STG configurations across a
single device or multiple devices. It supports the rcVlan and rcStg MIBs.
VLAN
A VLAN is a collection of ports on one or more switches that defines a broadcast
domain. You can assign ports to a VLAN or you can create a policy VLAN, which
determines the port’s membership in the VLAN based on the traffic entering that
port. For example, in an IP subnet-based VLAN, the port belongs to the VLAN
only if the traffic passing through the port is on the specified IP subnet.
