Policies-based
VLAN
assignment
MAC and IP
addresses-based or
MAC addresses, IP
addresses and
interfaces-based
VLAN assignment is
of high security. This
VLAN assignment
method does not allow
users to change MAC
addresses or IP
addresses based on
which VLANs are
configured.
Compared with other
VLAN assignment
methods, policies-
based VLAN
assignment has the
highest priority.
Each policy needs to
be manually
configured.
Policies-based VLAN
assignment is applicable
to small-scale networks
that have strict security
requirements and a large
number of traveling
users.
Inter-VLAN Communication
After VLANs are configured, users in a VLAN can communicate with each other. Users in
different VLANs cannot directly communicate with each other. Table 3-4 lists schemes for inter-
VLAN communication.
