78-5563-07 Rev.H0

New and Changed Information

When this feature is enabled, Multichassis Multilink PPP (MMP) Layer 2 Forwarding (L2F) tunnels

can still be created and established.

New Software Features in Release 12.0(5)T

The following new software enhancements are supported by the Cisco 2500 series in Release 12.0(5)T

and later releases.

Airline Product Set Enhancements

The Airline Product Set Enhancements feature, ALPS phase III, provides support for Mapping of

Airline Traffic over Internet Protocol (MATIP). MATIP is an industry standard protocol for transporting

airline protocol traffic across a TCP/IP network. This feature enables the end-to-end delivery of ALC

and UTS data streams between a Cisco router and the mainframe using TCP/IP. This feature removes

the X.25 (AX.25 or EMTOX) requirements for communication with the host reservation system by

enabling TCP/IP communication between the router and the airline host reservation system.

CNS Client for Cisco IOS Software

Cisco Networking Services (CNS) Client feature for Cisco IOS software enables authenticated

directory access. CNS Client for Cisco IOS software includes the following components:

• Lightweight Directing Access Protocol (LDAP) V.3 client

• Support to use Kerberos V.5 as security protocol for LDAP V.3 client

• CNS Event Services Client

• CNS Locator Services Client

• CNS IP Security (IPSec) virtual private network (VPN) Provisioning Agent

• CNS Configuration Change Notification Agent

• CNS Provisioning Agent

LDAP V.3 client functionality enables Cisco IOS software-based applications to securely authenticate

to a CNS for Active Directory (CNS/AD) server using Kerberos V.5 as security protocol to retrieve or

store information such as policy and configuration data. Cisco IOS software-based applications publish

or subscribe to events using CNS event services client, enabling external applications using the

application programming interface (API) features of CNS to receive events or publish events to the

Cisco IOS device. This Cisco IOS software-based device will use CNS locator services client to locate

the nearest directory server using Domain Name System. The administrator need not configure the

device to locate the nearest directory server.

All the above-mentioned functionality is intended for use by internal Cisco IOS application developers.

CNS IPSec VPN provisioning agent enables the router to retrieve IPSec policies stored in the CNS/AD

server and configure itself, automating the provisioning of customer premises equipment devices for

IPSec VPN. CNS provisioning agent enables Cisco IOS device to be provisioned using CNS event

services.
