2 In 802.1X enforcement mode, the ESs must be able watch DHCP conversations and detect endpoints
by sniffing network traffic as it flows between the DHCP server and the endpoints. Select one of the
following radio buttons:
remote—In more complex deployments, it is often impossible (in the case of multiple ESs or
■
multiple DHCP servers) or undesirable to span switch ports. In this case the DHCP traffic
monitoring and endpoint detection can be run remotely by installing and configuring the
endpoint activity capture software on each DHCP server involved in the 802.1X deployment. In
this case, choose the remote option.
local—In simple configurations, it is possible to span, or mirror, the switch port into which the
■
DHCP server is connected. The eth1 interface of the ES is then plugged into the spanned port and
endpoint traffic is monitored on the eth1 interface. In this case, choose the local option.
3 Click ok.

Now you must enable the endpoint for 802.1X. If you do not, the endpoint can never pass the initial
challenge from the switch, as the switch searches for an 802.1X-enabled endpoint. This sections
describes how to set up the following endpoints for 802.1X:
Windows XP Professional endpoint
●
Windows XP Home endpoint
●
Windows 2000 Professional endpoint
●
Windows Vista endpoint
