Plan the Zones
Zones are logical groupings of VLANs that have the same trust levels or
security needs. You can create common firewall policies that apply to all
members of a zone or to selected members of a zone.
You should plan your zones before beginning to configure the TMS zl Module
for several reasons:
■ Planning the zones helps you to define your security policies clearly
before you begin to implement them.
■ During the initial setup, you must configure the correct management-
access zone
■ To associate a VLAN with a zone, that VLAN must exist on the module’s
host switch. You must ensure that all of the VLANs that you want to control
have been extended to the host switch.
