Multiple mode allows for any number of clients to have access once a single client has been authenticated. Ports on Cisco 85x and Cisco 87x routers can be set only to multiple host mode. Note Single mode is disabled for these routers.
Page 69 The default setting is 30 seconds. Supplicant Reply Timeout Enter the time, in seconds, that your Cisco IOS router waits for a reply from an 802.1x client before timing out its connection to that client. Values must be in the range of 1–65535 seconds.
Page 70: Lan Wizard: Radius Servers For 802.1X Authentication
The source IP address in the RADIUS packets sent from the router must be configured as the NAD IP address in the Cisco ACS version 3.3 or later. If you choose Router chooses source, the source IP address in the RADIUS packets will be the address of interface through which the RADIUS packets exit the router.
Page 71 Chapter 4 802.1x Authentication LAN Wizard: RADIUS Servers for 802.1x Authentication Cisco IOS software allows a single RADIUS source interface to be configured on Note the router. If the router already has a configured RADIUS source and you choose a different source, the source IP address placed in the packets sent to the RADIUS server changes to the IP address of the new source, and may not match the NAD IP address configured on the Cisco ACS.

Generic routing encapsulation (GRE) is a tunneling protocol developed by Cisco that can encapsulate a wide variety of protocol packet types inside IP tunnels, creating a virtual point-to-point link to Cisco routers at remote points over an IP internetwork. By connecting multiprotocol subnetworks in a single-protocol backbone environment, IP tunneling using GRE allows network expansion across a single-protocol backbone environment.

Imported signatures are stored in a signature definition file (SDF).
Page 655 You can only import signatures from the router if the router has a DOS-based file Note system. SDFs are available from Cisco. Click the following URL to download an SDF from Cisco.com (requires login): http://www.cisco.com/cgi-bin/tablebuild.pl/ios-sigup Cisco maintains an alert center that provides information on emerging threats.

Page 979 Route maps enable you to control information that is added to the routing table. route map Cisco SDM automatically creates route maps to prevent NAT from translating specific source addresses when doing so would prevent packets from matching criteria in an IPSec rule.

Page 983 SSL VPN Secure Socket Layer Virtual Private Networks. SSL VPN is a feature that enables a supported Cisco router to provide remote clients secure access to network resources by creating an encryption tunnel across the Internet using the broadband or ISP dial connection that the remote client uses.
Page 984 Glossary standard rule In Cisco SDM, a type of access rule or NAT rule. Standard rules compare a packet’s source IP address against its IP address criteria to determine a match.Standard rules use a wildcard mask to determine which portions of the IP address must match.
