System Configuration
Quarantining, General
3-52
2. In the Quarantine method area, select one of the following quarantine
methods:
•
802.1X
– When using the 802.1X quarantine method, NAC 800 must sit
in a place on the network where it can communicate with your
RADIUS server, which communicates with your switch or router,
which performs the quarantining.
• DHCP – When configured with a DHCP quarantine area, NAC 800 must
sit inline with your DHCP server. All endpoints requesting a DHCP IP
address are issued a temporary address on a quarantine subnetwork.
Once the endpoint is allowed access, the IP address is renewed, and
the main DHCP server assigns an address to the main LAN. With a
multiple subnetwork or VLAN network, one quarantine area must be
configured for each subnetwork. See “Remote Device Activity Cap-
ture” on page 12-1 for information on using multiple DHCP servers.
• Inline – When using the inline quarantine method, NAC 800 must be
placed on the network where all traffic to be quarantined passes
through NAC 800. It must be inline with an endpoint like a VPN.
3. Click ok .

Home window>>System configuration>>Quarantining
1. Select one of the following in the
Access mode
area:
• normal – Either allows or quarantines endpoints depending on the
setup of the enforcement sever.
• allow all – Endpoints are tested; however, they are always given
access to the production network.
NOTE:
If you are setting up a cluster for the first time, and you have not yet added
an ES, select allow all until you have finished configuring NAC 800.
