These release notes are for Cisco IOS Release 12.3(1a)BW running on the Cisco Multiprocessor WAN Application Module (MWAM) in the Cisco 7600 Internet router. These release notes are updated as needed to describe new features, memory requirements, hardware support, software platform deferrals, and changes to the microcode and related documents.
For a list of the software caveats that apply to Cisco IOS Release 12.3(1a)BW, see the "Caveats in Cisco IOS Release 12.3(1a)BW" section.
To see the release notes for Cisco IOS Release 12.3, see http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123relnt/xprn123/index.htm .
This document contains the following sections:
The Cisco Multiprocessor WAN Application Module (MWAM) is a Cisco IOS software application module that you can install into the Cisco 7600 Series Internet Routers. The MWAM allows you to run multiple instances of Cisco Ethernet Service Aggregation applications, such as L2TP Network Server (LNS) and Service Selection Gateway (SSG) application software.
The MWAM requires the following system configuration:
Refer to the Release Notes for Cisco IOS Release 12.2(14)ZA1 on the Catalyst 6500 Series and Cisco 7600 Series Supervisor Engine and MSFC for specific information about the Supervisor Engine 2.
Refer to the C isco Multiprocessor WAN Application Module Installation and Configuration Notes for the Cisco 7600 Series Internet Router for specific information about configuring the MWAM.
MWAM memory is not configurable.
To use a MWAM module, you need a Cisco Catalyst 6500 Series Supervisor Engine 2 with an MSFC 2 and any interface module with ports to connect server and client networks.
 |
Note Release 12.2(14)ZA1 does not support optical service modules (OSMs) or the Catalyst 6500 Series and Cisco 7600 Series Internet Router FlexWAN module because of open caveats CSCdx94072, CSCdx83584, CSCdx57576, CSCdx60406, CSCdx69921, and CSCdx63685. |
This section describes system requirements for MWAM with Cisco IOS Release 12.3(1a)BW.
MWAM with Cisco IOS Release 12.3(1a)BW requires the following hardware components:
A Hardware-Software Compatibility Matrix is available on CCO for users with CCO login accounts. This matrix allows users to search for supported hardware components by entering a Cisco platform and IOS release. The Hardware-Software Compatibility Matrix tool is available at the following URL:
http://www.cisco.com/cgi-bin/front.x/Support/HWSWmatrix/hwswmatrix.cgi
MWAM with Cisco IOS Release 12.3(1a)BW requires the following software components:
Cisco IOS Release 12.3(1a)BW is a special release that supports Cisco IOS Release 12.(3)1and the same features that are in previous Cisco IOS Release 12.2 releases, with the addition of MWAM platform support.
The MWAM provides two processor complexes that are equipped with 1 GB memory shared between two processors (512 MB each). The remaining processor complex is equipped with 512 MB memory shared between two processors (256 MB each). The total memory capacity for the MWAM is 2.5 GB.
The MWAM memory is not configurable.
To determine the version of Cisco IOS software running on your router, log in to the router and enter the show version EXEC command:
For information on upgrading to a new software release, see the product bulletin Cisco IOS Software Upgrade Ordering Instructions located at:
http://www.cisco.com/warp/public/cc/pd/iosw/prodlit/957_pp.htm
For information on upgrading images on the MWAM, refer to the Cisco Multiprocessor WAN Application Module Installation and Configuration Notes for the Cisco 7600 Series Internet Router.
|
Note The image download process automatically loads the Cisco IOS image onto the three processor complexes on the MWAM. |
This section describes the features associated with the MWAM with Cisco IOS Release 12.3(1a)BW.
Each MWAM card's six CPUs share a common Cisco IOS image but each runs independently of the others so that there are six unique IOS instances running simultaneously. These IOS instances use gigabit Ethernet 802.1Q trunk port interfaces to carry VLAN encapsulated traffic to and from the network through the Cisco 7600 switching hardware. Each processor complex (housing two IOS instances) shares one gigabit Ethernet interface.
Each processor complex has a 1 Gigabit Ethernet (GE) interface to the switching bus. This connection appears as a GE interface from the Supervisor module.
The MWAM connects to the Cisco Catalyst 6500 switch/Cisco 7600 router bus for data and control traffic.
The MWAM with Cisco IOS Release 12.3(1a)BW provides the SSG features on the MWAM platform.
The SSG requires that you bind the user access network and services network to specific interfaces. Only one physical interface is available to the SSGs on the MWAM, which connects to the switching bus and Cisco Catalyst 6500 Series Supervisor Engine 2 module. Subinterfaces are defined with 802.1Q encapsulation and contain multiple VLANs, each representing one network interface.
The full description of SSG features is included in the release documentation:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123newft/123limit/1231abw/index. htm.
The MWAM with Cisco IOS Release 12.3(1a)BW also provides L2TP Network Server (LNS) on the MWAM platform.
LNS operates on any platform capable of PPP termination. It handles the server side of the L2TP protocol. Since L2TP relies on the single media over which L2TP tunnels arrive, an LNS may have only a single LAN or WAN interface, yet still be able to terminate calls arriving at any of the LACs' full range of PPP interfaces (async ISDN). LNS is the initiator of outgoing calls and the receiver of incoming calls.
For more information, see http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123mindx/new123.htm#34929.
External physical interfaces provided by the supported platforms are not visible to the SSG software. This is an important advantage of the MWAM implementation when compared to the 7200/7400 platform. The MWAM implementation protects the SSG from interface and link failures. As long as the platform provides redundant links to other system components (for example, GGSN, AAA servers), the SSG configuration is not affected and its operation is maintained.
The following sections describe the open, resolved, closed, and unreproducible caveats for the MWAM with Cisco IOS Release 12.3(1a)BW.
