Feature Set Tables

The Cisco IOS software is packaged in feature sets consisting of software images, depending on the platform. Each feature set contains a specific set of Cisco IOS features. Release 12.2(15)JK supports the same feature sets as Releases 12.2 and 12.2(15)T, but Release 12.2(15)JK includes new features supported by the Cisco 3200 Series Mobile Access Router. Release 12.2(15)JK5 is a rebuild of Release 12.2(15)JK and includes only bug fixes, it does not include any new features.


Caution The Cisco IOS images with strong encryption (including, but not limited to, 168-bit [3DES] data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States will likely require an export license. Customer orders can be denied or subject to delay as a result of United States government regulations. When applicable, the purchaser/user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

Table 2 lists the features and feature sets supported in Release 12.2(15)JK5.

The table uses the following conventions:

In—The number in the "In" column indicates the Cisco IOS release in which the feature was introduced. For example, "12.2(15)JK" indicates that the feature was introduced in 12.2(15)JK. If a cell in this column is empty, the feature was included in a previous release or in the initial base release.

Yes—The feature is supported in the software image.

No—The feature is not supported in the software image.


Note This feature set table contains only a list of selected features, which are cumulative for Release 12.2(15)nn early deployment releases only (nn identifies each early deployment release). The table does not list all features in each image; additional features are listed in Cross-Platform Release Notes for Cisco IOS Release 12.2(15)T and in Release 12.2(15)T Cisco IOS documentation.

Resolved Caveats - Release 12.2(15)JK5

This section documents possible unexpected behavior by Cisco IOS Release 12.2(15)JK5 and describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCei61732

Cisco IOS may permit arbitrary code execution after exploitation of a heap-based buffer overflow vulnerability. Cisco has included additional integrity checks in its software, as further described below, that are intended to reduce the likelihood of arbitrary code execution.

Cisco has made free software available that includes the additional integrity checks for affected customers.

This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20051102-timers.shtml.

CSCeb85136

Symptoms: An IP packet that is sent with an invalid IP checksum may not be dropped.

Conditions: This symptom is observed if the IP checksum is calculated with a decreased time-to-live (TTL) value. For example, in the situation where the IP checksum must be 0x1134 with a TTL of 3, if the packet is sent with an IP checksum of 0x1234 that is calculated by using a TTL value of 2, the packet is not dropped. In all other cases, packets with incorrect checksums are dropped.

Workaround: There is no workaround.

CSCeb88239

Symptoms: A router that runs RIPng may crash after receiving a malformed RIPng packet, causing a Denial of Service (DoS) on the device.

Conditions: This symptom is observed when the ipv6 debug rip command is enabled on the router. Malformed packets can normally be sent locally. However, when the ipv6 debug rip command is enabled, the crash can also be triggered remotely. Note that RIP for IPv4 is not affected by this vulnerability.

Workaround: There is no workaround.

CSCee45312

Remote Authentication Dial In User Service (RADIUS) authentication on a device that is running certain versions of Cisco Internetworking Operating System (IOS) and configured with a fallback method to none can be bypassed.

Systems that are configured for other authentication methods or that are not configured with a fallback method to none are not affected.

Only the systems that are running certain versions of Cisco IOS are affected. Not all configurations using RADIUS and none are vulnerable to this issue. Some configurations using RADIUS, none and an additional method are not affected.

Cisco has made free software available to address this vulnerability. There are workarounds available to mitigate the effects of the vulnerability.

More details can be found in the security advisory which posted at the following URL:

http://www.cisco.com/warp/public/707/cisco-sa-20050629-aaa.shtml

CSCeg15044

Symptoms: Although there are free tty lines, you cannot make a Telnet connection and a "No Free TTYs error" message is generated.

Conditions: This symptom is observed when there are simultaneous Telnet requests.

Workaround: "clear tcp tcb" should clear the line.

CSCeh13489

Symptoms: A router may reset its Border Gateway Protocol (BGP) session.

Conditions: This symptom is observed when a Cisco router that peers with other routers receives an Autonomous System (AS) path with a length that is equal to or greater than 255.

Workaround: Configure the bgp maxas limit command in such as way that the maximum length of the AS path is a value below 255. When the router receives an update with an excessive AS path value, the prefix is rejected and recorded the event in the log.

CSCsa52807

A document titled "ICMP Attacks Against TCP," which describes how the Internet Control Message Protocol (ICMP) could be used to perform Denial of Service (DoS) attacks against the Transmission Control Protocol (TCP), has been made publicly available through the Internet Engineering Task Force (IETF) Internet Draft process (draft-gont-tcpm-icmp-attacks-03.txt).

These attacks, which affect only sessions terminating or originating on a device itself, can be of three types:

1. Attacks that use ICMP "hard" error messages.

2. Attacks that use ICMP "fragmentation needed and Don't Fragment (DF) bit set" messages, also known as Path Maximum Transmission Unit Discovery (PMTUD) attacks.

3. Attacks that use ICMP "source quench" messages.

Successful attacks may cause connection resets or reduction of throughput in existing connections, depending on the attack type.

Multiple Cisco products are affected by the attacks described in this Internet draft.

Cisco has made free software available to address these vulnerabilities. There are also workarounds available to mitigate the effects. More details can be found in the security advisory at the following URL:

http://www.cisco.com/warp/public/707/cisco-sa-20050412-icmp.shtml

The disclosure of these vulnerabilities is being coordinated by the National Infrastructure Security Coordination Centre (NISCC), based in the United Kingdom. NISCC is working with multiple vendors whose products are potentially affected. Its posting can be found at: http://www.niscc.gov.uk/niscc/docs/re-20050412-00303.pdf?lang=en

Resolved Caveats - Release 12.2(15)JK4

This section documents possible unexpected behavior by Cisco IOS Release 12.2(15)JK4 and describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCef68324

Cisco Internetwork Operating System (IOS) software is vulnerable to a Denial of Service (DoS) and potentially an arbitrary code execution attack from a specifically crafted IPv6 packet. The packet must be sent from a local network segment. Only devices that have been explicitly configured to process IPv6 traffic are affected. Upon successful exploitation, the device may reload or be open to further exploitation.

Cisco has made free software available to address this vulnerability for all affected customers.

More details can be found in the security advisory that is posted at http://www.cisco.com/warp/public/707/cisco-sa-20050729-ipv6.shtml.

Resolved Caveats - Release 12.2(15)JK3

This section documents possible unexpected behavior by Cisco IOS Release 12.2(15)JK3 and describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCef44225—IPSec (ESP-AH) doing PMTUD vulnerable to spoofed ICMP packets.

A document that describes how the Internet Control Message Protocol (ICMP) could be used to perform a number of Denial of Service (DoS) attacks against the Transmission Control Protocol (TCP) has been made publicly available. This document has been published through the Internet Engineering Task Force (IETF) Internet Draft process, and is entitled "ICMP Attacks Against TCP" (draft-gont-tcpm-icmp-attacks-03.txt).

These attacks, which only affect sessions terminating or originating on a device itself, can be of three types:

Resolved Caveats - Release 12.2(15)JK2

This section documents possible unexpected behavior by Cisco IOS Release 12.2(15)JK2 and describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCed40933

Cisco Internetwork Operating System (IOS) Software is vulnerable to a Denial of Service (DoS) attack from crafted IPv6 packets when the device has been configured to process IPv6 traffic. This vulnerability requires multiple crafted packets to be sent to the device which may result in a reload upon successful exploitation.

More details can be found in the security advisory, which is posted at http://www.cisco.com/warp/public/707/cisco-sa-20050126-ipv6.shtml.

CSCed78149

A document that describes how the Internet Control Message Protocol (ICMP) could be used to perform a number of Denial of Service (DoS) attacks against the Transmission Control Protocol (TCP) has been made publicly available.

CSCee67450

A Cisco device running Cisco IOS and enabled for the Border Gateway Protocol (BGP) is vulnerable to a Denial of Service (DoS) attack from a malformed BGP packet. Only devices with the command `bgp log-neighbor-changes' configured are vulnerable. The BGP protocol is not enabled by default, and must be configured in order to accept traffic from an explicitly defined peer. Unless the malicious traffic appears to be sourced from a configured, trusted peer, it would be difficult to inject a malformed packet.

If a misformed packet is received and queued up on the interface, this bug may also be triggered by other means which are not considered remotely exploitable such as the use of the command `show ip bgp neighbors' or running the command `debug ip bgp <neighbor> updates' for a configured bgp neighbor.

Cisco has made free software available to address this problem.

For more details, please refer to this advisory, available at http://www.cisco.com/warp/public/707/cisco-sa-20050126-bgp.shtml

CSCef46191—Unable to telnet.

A specifically crafted Transmission Control Protocol (TCP) connection to a telnet or reverse telnet port of a Cisco device running Internetwork Operating System (IOS) may block further telnet, reverse telnet, Remote Shell (RSH), Secure Shell (SSH), and in some cases Hypertext Transport Protocol (HTTP) access to the Cisco device. Telnet, reverse telnet, RSH and SSH sessions established prior to exploitation are not affected.

All other device services will operate normally. Services such as packet forwarding, routing protocols and all other communication to and through the device are not affected.

Cisco will make free software available to address this vulnerability. Workarounds, identified below, are available that protect against this vulnerability.

The Advisory is available at

http://www.cisco.com/warp/public/707/cisco-sa-20040827-telnet.shtml

CSCef84988—Incorrect HTTP Files in TAR.

CSCin82407

Cisco Internetwork Operating System (IOS) Software release trains 12.2T, 12.3 and 12.3T may contain vulnerabilities in processing certain Internet Key Exchange (IKE) Xauth messages when configured to be an Easy VPN Server.

Successful exploitation of these vulnerabilities may permit an unauthorized user to complete authentication and potentially access network resources.

This advisory will be posted to http://www.cisco.com/warp/public/707/cisco-sa-20050406-xauth.shtml

Resolved Caveats - Release 12.2(15)JK1

This section documents possible unexpected behavior by Cisco IOS Release 12.2(15)JK1 and describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCed73366—The show tech command does not show flash output.

The show tech command on Cisco 3201 WMIC does not print the "show flash: all" information.

CSCed89520—Up to 12 sec needed for ping to pass after roaming.

When roaming back and forth from one access point to another access point, it sometime takes up to 12 sec for download traffic, for WGB client, to resume. The access point displays that the WGB is associated but traffic does not pass.

The download traffic is delayed to restart if there is no upload from WGB client after WGB associates to new access point.

CSCee49654—Wired client of WGB becomes disassociated from Cisco 3201 WMIC (root access point).

When a WGB and its wired client associate to a Cisco 3201 WMIC configured as a root access point, after approximately 5 min, the wired client is no longer associated, as shown by the show dot11 associations command.

Workaround

Maintain some traffic going out from the wired client like keepalives or Mobile IP solicitations (if using Mobile IP) continuously being sent at regular time every intervals, where the time interval is less than 5 min. This will ensure the wired client is not timed out on the root access point.

Open Caveats - Release 12.2(15)JK

This section documents possible unexpected behavior by Cisco IOS Release 12.2(15)JK and describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCee19874—Unexpected exception CPU vector cause WMIC to crash.

This issue is found by the script only, and happens intermittently. This script performs the following configuration continuously:

a. Static IP address on BVI1

b. DHCP address on BVI1

c. WGB roaming between two bridges

d. SNMP linkup/down traps send from WGB to MAR

e. Ping between WGB and bridge.

CSCee20478—The Cisco 3201 WMIC/Cisco Aironet 1310 bridge console freezes if there is continuous change in Static IP/DHCP.

When the BVI1 interface is fast configured between static and DHCP IP addresses, sometimes both processes (Exec and DHCP) try to get a semaphore to save the IP address on NVRAM. When one process gets the semaphore, it will still hold the semaphore if it cannot open the file system. At the same time if another process from console tries to get the same semaphore, then the console will be frozen.

Workaround

Do not configure the BVI1 interface continuously between static and DHCP IP addresses.

CSCee35755—WGB 350 does not pass its IP address in Cisco Aironet Ext field in association request.

CSCee30548—Root bridge cannot ping non-root bridges for point-to-multipoint scenario.

When VLAN is configured, after the association of a root bridge with two or more non-root bridges, ping from root bridge to non-root bridges fail. The ping will succeed once the non-root bridge entry gets aged and deleted from the root bridge table.

Workaround

Disable Spanning Tree Protocol under the VLAN interface.

CSCee34600—WMIC/Cisco Aironet 1310 bridge advertises SSID when guest mode is disabled.

The guest-mode SSID is used in beacon frames and probe response frames to probe request that specify the empty or wildcard SSID. If no guest-mode SSID exists, the access point probe response to probe request of empty SSID still contains SSID.

CSCee44432—When antenna are set to transmit, they will still receive.

When WMIC antennas are set in transmit or receive mode, they will continue to both transmit and receive.

CSCee49654—Wired client of WGB becomes disassociated from WMIC (root access point)

When a WGB and its wired client associate to a WMIC configured as a root Access Point, after approximately 5 min, the wired client is no longer associated as reflected by the show dot11 associations command.

Workaround

Configure the outgoing traffic from the wired client like keepalives or Mobile IP solicitations (continuously being sent every interval, where the time interval is less than 5 min). This ensures the wired client is not timed out on the root access point.

Resolved Caveats - Release 12.2(15)JK

This section documents possible unexpected behavior by Cisco IOS Release 12.2(15)JK and describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCee33359—WMIC access point reloads when heavy traffic pass through.

CSCee08584

Cisco IOS trains 12.1YD, 12.2T, 12.3 and 12.3T, when configured for Cisco's IOS Telephony Service (ITS), Cisco CallManager Express (CME) or Survivable Remote Site Telephony (SRST) may contain a vulnerability in processing certain malformed control protocol messages.

A successful exploitation of this vulnerability may cause a reload of the device and could be exploited repeatedly to produce a Denial of Service (DoS). This advisory is available at http://www.cisco.com/warp/public/707/cisco-sa-20050119-itscme.shtml

Cisco has made free software upgrades available to address this vulnerability for all affected customers.

This vulnerability is documented by Cisco bug ID CSCee08584.

CSCed89520—Up to 12 sec needed for ping to pass after roaming.

When roaming back and forth from one access point to another access point, it sometime takes up to 12 sec for download traffic to resume for WGB client. The access point displays that the WGB is associated but traffic does not pass.

The download traffic is delayed to restart if there is no upload from WGB client after WGB associates to new access point.

Workaround

Configure SNMP link-state trap mechanism between MAR and WMIC.

CSCed93298—Client does not pass its IP address in the Cisco Aironet Ext field in association request.

When doing a show dot11 associations command on the Cisco 3201 WMIC configured as a root access point, the IP address of any CB21AG client which is associated to the WMIC may be displayed as 0.0.0.0. After two or more minutes, the CB21AG client's IP address will be displayed correctly.

Workaround

Ping the CB21AG client from the Cisco 3201 WMIC, or vice-versa.

CSCec16481

A Cisco device running Internetwork Operating System (IOS) and enabled for the Open Shortest Path First (OSPF) Protocol is vulnerable to a Denial of Service (DoS) attack from a malformed OSPF packet. The OSPF protocol is not enabled by default.

The vulnerability is only present in IOS release trains based on 12.0S, 12.2, and 12.3. Releases based on 12.0, 12.1 mainlines and all IOS images prior to 12.0 are not affected. Refer to the Security Advisory for a complete list of affected release trains.

Further details and the workarounds to mitigate the effects are explained in the Security Advisory which is available at the following URL:

http://www.cisco.com/warp/public/707/cisco-sa-20040818-ospf.shtml.

Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support Website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.


Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

For a complete list of Cisco TAC contacts, go to this URL:

http://www.cisco.com/techsupport/contacts

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
