Figure 9-47 JWAC Global Settings window

The fields that can be configured are described below:

Parameter

Description

JWAC State

Use this selection menu to either enable or disable JWAC on the Switch.

Virtual IP

This parameter specifies the JWAC Virtual IP address that is used to accept

authentication requests from an unauthenticated host. The Virtual IP address of JWAC is

used to accept authentication requests from an unauthenticated host. Only requests sent

to this IP will get a correct response.

NOTE:

This IP does not respond to ARP requests or ICMP packets.

Virtual URL

Here the user can enter the Virtual URL used.

UDP Filtering

This parameter enables or disables JWAC UDP Filtering. When UDP Filtering is

Enabled

all UDP and ICMP packets except DHCP and DNS packets from unauthenticated hosts

will be dropped.

Port Number (1-65535)

This parameter specifies the TCP port that the JWAC Switch listens to and uses to finish

the authenticating process.

Forcible Logout

This parameter enables or disables JWAC Forcible Logout. When Forcible Logout is

Enabled

, a Ping packet from an authenticated host to the JWAC Switch with TTL=1 will be

regarded as a logout request, and the host will move back to the unauthenticated state.

Authentication Protocol

This parameter specifies the RADIUS protocol used by JWAC to complete a RADIUS

authentication. The options include

Local

EAP

MD5

PAP

CHAP

MS CHAP

, and

CHAPv2

Redirect State

This parameter enables or disables JWAC Redirect. When the redirect quarantine server

is enabled, the unauthenticated host will be redirected to the quarantine server when it

tries to access a random URL. When the redirect JWAC login page is enabled, the

unauthenticated host will be redirected to the JWAC login page in the Switch to finish

authentication. When redirect is disabled, only access to the quarantine server and the

JWAC login page from the unauthenticated host are allowed, all other web access will be

denied.

NOTE:

When enabling redirect to the quarantine server, a quarantine server must be

configured first.

Redirect Destination

This parameter specifies the destination before an unauthenticated host is redirected to
