Feature Support

Cisco IOS software is packaged in feature sets that consist of software images that support specific platforms. The feature sets available for a specific platform depend on which Cisco IOS software images are included in a release. Each feature set contains a specific set of Cisco IOS features.


Caution Cisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to U.S. government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay because of U.S. 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.

The feature set tables have been removed from the Cisco IOS Release 12.4 release notes to improve the usability of the release notes documentation. The feature-to-image mapping that was provided by the feature set tables is available through Cisco Feature Navigator.

Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or by feature set (software image). Under the release section, you can compare Cisco IOS software releases side by side to display both the features unique to each software release and the features that the releases have in common.

Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

http://www.cisco.com/go/cfn

For frequently asked questions about Cisco Feature Navigator, see the FAQs at the following URL:

Additional Notes for the Cisco 800 Series Routers

This section contains important information about using the Cisco 800 series routers with Cisco IOS Release 12.4 software.

caller-id Command

When the caller-id command (which appears under "dial-peer" in the configuration commands) is used, the default setting is "off" for Japan and "on" for the United States. This command was introduced in Cisco IOS Release 12.1(2)XF.

DHCP Client Support

To configure the router for DHCP client support, perform the following steps:


Step 1 Configure the Bridge-Group Virtual Interface (BVI) by entering the ip address dhcp client-id ethernet0 command.

Specifying client-id ethernet0 causes the MAC address of the Ethernet interface to be used as the client ID when the DHCP request is sent. Otherwise, the MAC address of the BVI is used as the client ID.

Step 2 Configure Network Address Translation (NAT):

a. Configure the BVI by entering the nat outside command.

b. Configure the Ethernet interface by entering the nat inside command.

c. Create an access list under NAT by entering the access-list 1 permit ip-address command to match all Ethernet IP addresses.

d. Configure the source list under NAT by entering the ip nat inside source list 1 interface BVI 1 overload command.

Downloading Images

Delete files in the router flash memory before attempting to download new images.


Caution Use the delete command, not the erase command, to free up space. Entering the erase command removes all files, including the configuration.

Flash Memory

Cisco 800 series routers use 4 MB of flash memory for storing internal information such as the ROM monitor. Only the remainder of the flash memory is available for storing Cisco IOS images; this remaining memory is displayed by using the show flash command. For example, if the router reports 8 MB of flash memory, the actual amount of onboard flash memory is 12 MB, even though only 8 MB are displayed and available for Cisco IOS image storage.

Multilink PPP and Interleaving

Multilink PPP fragments large data packets to allow small voice packets to be interleaved between them. However, apart from FIFO queueing, no other kind of output queueing mechanisms are currently supported with PPP over ATM. Consequently, when multilink PPP is configured on the Cisco 800 series routers, large packets are fragmented, but small voice packets are not interleaved between them.

NAT Support for H.323 Signaling

Network Address Translation (NAT) does not support alerting H.225 messages; therefore, NAT communication cannot be established between router endpoints. NAT support for H.323 signaling is limited to the application NetMeeting.

PPP over AAL5SNAP Encapsulation Support

PPP over AAL5SNAP encapsulation is currently not supported, although the context-sensitive help mentions that it can be configured.

Router Clock—CSCdp09409

To run IP Security (IPSec) successfully, the Cisco 800 series router clock must be set accurately. Cisco 800 series router clocks are set and maintained using Simple Network Time Protocol (SNTP). For best results, set up a Network Time Protocol (NTP) server to periodically send time information messages to Cisco 800 series routers. See the SNTP configuration and command reference documentation for configuration instructions. If you do not have an NTP server, you must reset the Cisco 800 series router clock using the clock set command each time you restart the router.

Dial Peer Limitation

The isdn answer1 and isdn answer2 commands determine which called telephone numbers, for example 555-0100 and 555-0199, a Cisco 800 series router can answer. Using these commands limits a router to using the two dial peers that contain the telephone numbers 555-0100 and 555-0199. (When not using these commands, a router can use up to six dial peers.)

Excessive ISDN Line Activation

The following protocols send updates that can cause an ISDN line to be activated excessively, thereby increasing your monthly ISDN line cost:

Cisco Discovery Protocol (CDP)

Internetwork Packet Exchange (IPX)

IP

Simple Network Time Protocol (SNTP)

User Datagram Protocol (UDP)

For information on preventing this situation, see the Cisco 800 Series Routers Software Configuration Guide. This guide contains information on setting up extended access lists to prevent IP, UDP, IPX, and SNTP updates from activating the ISDN line. For CDP, ensure that you enter the no cdp enable command to disable CDP.

Hanging During Boot

If an illegal console configuration is issued to the router, the console will fail the POST test during boot and cause the router to pause indefinitely. There is no way to recover a unit in this state except by pulling the soldered boot flash and reburning the boot ROM.

This problem has been resolved in TinyROM version 1.0(3), a downloadable ROM upgrade available from Cisco.com. Please contact Cisco to upgrade to this version or later to prevent this problem from occurring.

Phone Mate Model 9200 Answering Machine

A Phone Mate model 9200 answering machine failed to recognize the ringing signal sent by AMD R79 ringing SLIC. This failure was confirmed by testing against Phone Mate model 3750 and the newer 9300 model.

B-Channel Activation

When a call comes in, a B channel is activated. If the amount of traffic on the B channel exceeds a threshold, the other B channel is activated. If the amount of traffic falls below the threshold, one of the B channels is deactivated. The B channel that is initially activated when the call comes in is not necessarily B1, nor is the B channel that is deactivated when the traffic level lessens necessarily B2.
