Introduction
With Cisco IOS Release 12.4(16)MR and later, Cisco 3825 series integrated services routers can be used in an Internet Protocol Radio Access Network (IP RAN) environment. The Cisco IP RAN feature provides both:
•
Global System for Mobile Communication (GSM) Abis Optimization over IP and
•
The Cisco IP RAN feature enables bandwidth efficient transport of GSM and UMTS traffic between the Base Transceiver Station (BTS) and the Base Station Controller (BSC) in GSM RANs and between Node B and Radio Network Controllers (RNC) in UMTS RANs. This results in significant reductions in operating expenditures to the mobile wireless operator and enables new revenue-generating services for the future.
System Requirements
When being implemented in an IP RAN solution, the Cisco 3825 series integrated services router requires the following minimum software installation:
•
Memory Requirements
Table 1 lists the required memory for using this software.
Hardware Supported
The following cards are supported on the Cisco 3825 router:

Caveats
This section documents the open and resolved caveats for the Cisco 3825 series integrated services router running Cisco IOS Release 12.4(16)MR through Cisco IOS Release 12.4(19)MR. Only severity 1 through 3 caveats are included.
Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these three severity levels.
Caveats in Cisco IOS Software Releases 12.4 Mainline and Cisco IOS Software Releases 12.4T are also in Cisco IOS Release 12.4(16)MR through Cisco IOS Release 12.4(19)MR.

The Cisco IOS Intrusion Prevention System (IPS) feature contains a vulnerability in the processing of certain IPS signatures that use the SERVICE.DNS engine. This vulnerability may cause a router to crash or hang, resulting in a denial of service condition.
Cisco has released free software updates that address this vulnerability. There is a workaround for this vulnerability.
NOTE: This vulnerability is not related in any way to CVE-2008-1447 - Cache poisoning attacks. Cisco Systems has published a Cisco Security Advisory for that vulnerability, which can be found at http://www.cisco.com/en/US/products/products_security_advisory09186a00809c2168.shtml.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080924-iosips.shtml.
CSCsq93138
Description: The user cannot specify the default IMA Group ID on an IMA interface. This is done solely by the system.
Workaround: By using the ima-group id command, the user can configure the IMA Group ID on an IMA interface. If the user configures an IMA Group ID with the system-selected default ID for an existing IMA interface, the system toggles the IMA interface to make the user-configured IMA Group ID the effective IMA Group ID. At the same time, the system toggles the original IMA interface to select a different default IMA Group ID.
Caveats in Cisco IOS Release 12.4(16)MR2
The following caveats are opened and resolved in Cisco IOS Release 12.4(16)MR2.

The Secure Shell server (SSH) implementation in Cisco IOS contains multiple vulnerabilities that allow unauthenticated users the ability to generate a spurious memory access error or, in certain cases, reload the device.
The IOS SSH server is an optional service that is disabled by default, but its use is highly recommended as a security best practice for management of Cisco IOS devices. SSH can be configured as part of the AutoSecure feature in the initial configuration of IOS devices, AutoSecure run after initial configuration, or manually. Devices that are not configured to accept SSH connections are not affected by these vulnerabilities.
Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-1159 has been assigned to this bug.
The Security Advisory for this issue is posted at
http://www.cisco.com/warp/public/707/cisco-sa-20080521-ssh.shtml
