Note You can find the most current Cisco IOS documentation on Cisco Connection Online (CCO). These electronic documents may contain updates and modifications made after the hard copy documents were printed. |
These release notes for the Cisco MC3810 multiservice access concentrator describe the enhancements provided in Cisco IOS Release 12.1(1)XA3, which is an early deployment release based on the Cisco IOS Release 12.1(2)T. Release notes are updated as needed to describe new features, memory requirements, hardware support, software platform deferrals, microcode or modem code changes, and related documents.
For a list of software caveats that apply to Release 12.1(1)XA3, refer to the "Caveats" section.
Use these release notes with Cross-Platform Release Notes for Cisco IOS Release 12.1 located on Cisco Connection Online (CCO) and the Documentation CD-ROM.
Cisco is changing the product numbers you use to order a specific Cisco IOS software image. In short, Cisco will remove the periods separating the release train, maintenance release, and build number. The following table provides some examples.
| Old Product Number | New Product Number | Release | Image Description |
|---|---|---|---|
S364AR1K2-12.0.7XK | S364AR1K2-12007XK | 12.0(7)XK | Cisco 3640 series IOS Enterprise/ SNA SW PLUS IP Sec 3DES |
S26CP-12.0.7XK | S26CP-12007XK | 12.0(7)XK | Cisco 2600 series IOS IP Plus |
These release notes describe the following topics:
As part of an enterprise backbone or as customer premises equipment (CPE) to service provider-managed network services, the Cisco MC3810 multiservice access concentrator reduces operating costs and complexity, and increases network throughput and performance. Cisco IOS software fully supports the Cisco MC3810 for multiprotocol routing, bridging, and Systems Network Architecture (SNA).
To make file management easier, the Cisco MC3810 provides a complete file system for software images, message files, and reports. The standard Flash memory size is either 8 MB or 16 MB, with 16-MB or 32-MB upgrade options that can simultaneously hold two code images for fail-safe upgrades.
You can manage the Cisco MC3810 by using standard Cisco management platforms and facilities such as CiscoView and the native remote log-in facilities provided by Telnet and rlogin. Three types of configuration interfaces are provided:
The HTTP-based interface allows configuration from any web browser such as Netscape Navigator or Microsoft Explorer. The SNMP MIB allows management of the Cisco MC3810 from SNMP managers, such as HP OpenView.
This section describes the system requirements for Cisco IOS Release 12.1(1)XA3:
| Feature Set | Image Name | Minimum Flash Memory | Minimum DRAM Memory | Runs From |
|---|---|---|---|---|
Enterprise Plus/VoIP and VoATM | mc3810-a2jsv5-mz | 16 MB | 64 MB | RAM |
Cisco IOS Release 12.1(1)XA3 supports the Cisco MC3810 multiservice access concentrator.

To make file management easy, the Cisco MC3810 provides a complete file system for software images, message files, and reports. The standard Flash memory size is 8 MB, and a 16-MB upgrade option can simultaneously hold two code images for fail-safe upgrades.
The following sections list new information about the Cisco MC3810 in Cisco IOS Release 12.1(1)XA3.
The following software enhancement is available for the Cisco MC3810 in Cisco IOS Release 12.1(1)XA3.
Voice over ATM with AAL2 Trunking enables the Cisco MC3810 series concentrators to carry voice traffic (for example, telephone calls and faxes) over ATM networks using ATM adaptation layer 2 (AAL2). AAL2 is the most bandwidth-efficient standards-based trunking method for transporting compressed voice, voice-band data, circuit-mode data, and frame-mode data over ATM infrastructures.
Voice over ATM with AAL2 trunking provides the following improvements to the Cisco MC3810 capabilities:
This section contains important information about the use of your Cisco IOS Release 12.1(1)XA3 software. Refer to the "Caveats" section for details on individual caveats closed within this release.
With Cisco IOS Release 12.0(7)T and later releases, the IGX Interworking feature is no longer supported by the Cisco MC3810. The following commands used to configure this feature are no longer supported beginning in this release:
With Cisco IOS Release 12.0(7)T and later releases, the Voice over HDLC feature is no longer supported by the Cisco MC3810.
This section describes important notes regarding use of the Cisco MC3810 with the Public Switched Telephone Network (PSTN).
Be careful when connecting switched voice ports on the Cisco MC3810 directly to the PSTN. Improper configurations can expose the corporate network to telephone fraud.
The Cisco MC3810 has the capability to connect a user from the PSTN directly to the corporate wide-area telephone network. Using the Cisco MC3810 as a phone switch, you can configure the access concentrator to switch the user to any location in that network, even to remote locations that are connected again to another PSTN. However, the Cisco MC3810 does not provide any mechanism to restrict users from calling after they are connected. Without proper network design, this condition could result in the unauthorized use of the corporate network for making calls at the corporation's expense. To prevent this from occurring, you should not connect a switched voice interface on the Cisco MC3810 directly to the PSTN. Instead, connect the interface to a PBX that implements a security scheme that prevents unauthorized use.
The same opportunity for illicit use does not exist for non-switched call types, such as pass-through connections (although the possibility for fraud does exist at the direct contact point). Pass-through calls create a path to a single location specified by the network administrator. For example, you might use a pass-through connection to pass a trunk from a PBX to the PSTN. In this case, the trunk on the PBX always passes straight through the Cisco MC3810 to the PSTN. As a result, the necessary security is provided by the PBX.
Caveats describe unexpected behavior or defects in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 are less serious. This section contains only open and resolved caveats for the current Cisco IOS maintenance release. All caveats in Release 12.1 and Release 12.1 T are also in Release 12.1(1)XA3.
For information on caveats in Cisco IOS Release 12.1, see Caveats for Cisco IOS Release 12.1, which describes caveats affecting all maintenance releases. For information on other caveats that also apply to this release, see Caveats for Cisco IOS Release 12.1 T, which lists severity 1 and 2 caveats, and is located on CCO and the Documentation CD-ROM.

This section describes possibly unexpected behavior by Release 12.1(1)XA3. Unless otherwise noted, these caveats apply to all 12.1 releases up to and including 12.1(1)XA3.
All of the caveats listed in this section are resolved in Cisco IOS Release 12.1(1)X3.
The following sections describe the documentation available for the Cisco MC3810. These documents consist of hardware and software installation guides, Cisco IOS configuration and command references, system error messages, feature modules, and other documents.
Documentation is available as printed manuals or electronic documents, except for feature modules, which are available online on CCO and the Documentation CD-ROM.

The Cisco IOS software documentation set consists of the Cisco IOS configuration guides, Cisco IOS command references, and several other supporting documents, which are shipped with your order in electronic form on the Documentation CD-ROM---unless you specifically ordered the printed versions.
Each module in the Cisco IOS documentation set consists of two books: a configuration guide and a corresponding command reference. Chapters in a configuration guide describe protocols, configuration tasks, Cisco IOS software functionality, and contain comprehensive configuration examples. Chapters in a command reference provide complete command syntax information. Use each configuration guide with its corresponding command reference.
