4.5.4 Configuring the NAC Inclusion List

Using NAC, the switch acts as an enforcement entity before allowing MU access to specific network
resources. NAC performs a MU host integrity check wherein a MU sends host integrity information to the
NAC server. The NAC server configuration is defined on the switch on a per WLAN basis. NAC verifies a MU's
compliance with the NAC server's security policy (not the switch).
For a NAC configuration example using the switch CLI, see
CLI on page 4-71.
An include list is a list of MAC addresses configured for a WLAN. During EAP authentication, the EAP server
(Radius or NAC server) is determined based on the MU's MAC address.
• All non-802.1x devices are partitioned into a WLAN (separate from a 802.1x enabled WLAN).
• Communication between devices in a 802.1x supported WLAN and a non 802.1x supported WLAN is
achieved by merging the WLANs within the same VLAN.
The switch uses the include list to add devices that are NAC supported. The following explains how
authentication is achieved using 802.1x. The switch authenticates 802.1x enabled devices using one of the
following:
• NAC Agent – NAC support is added in the switch to allow the switch to communicate with a LAN
enforcer (a laptop with a NAC agent installed).
• No NAC Agent – NAC support is achieved using an exclude list. For more information, see
Configuring the NAC Exclusion List on page
By default, a WLAN is NAC disabled. Each WLAN can be configured to:
• Conduct a NAC check for MU's connecting to the WLAN as well as perform an additional exclude
function, by attaching an exclude list to the WLAN.
• Do not perform NAC validation for MUs connecting to the WLAN.
Define the current Arbitrary Inter-frame Space Number (AIFSN). Higher-priority
traffic categories should have lower AIFSNs than lower-priority traffic categories.
This will causes lower-priority traffic to wait longer before trying to access the
medium.
Define the maximum duration a device can transmit after obtaining a transmit
opportunity. For higher-priority traffic categories, this value should be set to a low
number.
The CW Minimum is combined with the CW Maximum to make the Contention
screen. From this range, a random number is selected for the back off mechanism.
Select a lower value for high priority traffic.
The CW Maximum is combined with the CW Minimum to make the Contention
screen. From this range, a random number is selected for the back off mechanism.
Lower values are used for higher priority traffic
Select the DSCP or 802.1p radio buttons to choose between DSCP and 802.1p.
