Hardware Supported

Cisco IOS Release 12.2(2)XH2 supports the following Cisco 800 and Cisco 820 series routers:

Cisco 801-804 Routers

Cisco 805 Router

Cisco 826, Cisco 827, and Cisco 827-4V Routers

For detailed descriptions of new hardware features, see the "New and Changed Information" section.

Cisco 801-804 Routers

The Cisco 801-804 routers provide the following key hardware features:

Cisco 802 and Cisco 804 routers have an integrated NT-1, which eliminates the need for an external NT-1 in North America.

Cisco 803 and Cisco 804 routers provide connection to analog telephones or fax machines, which are connected to telephone services through an ISDN line.

Flash memory: Default is 8 MB, expandable to 12 MB. (4MB Flash soldered to the motherboard.)


Note To add additional Flash memory to the Cisco 801-804, remove the existing Flash card and install a new one.


Dynamic RAM: Default is 4 MB, expandable to 12 MB. (4MB Dynamic RAM soldered to the motherboard.)

ISDN B-channel LEDs are a different color from the other LEDs, which make them easy to distinguish.

Color-coded ports and cable reduce the chance of cabling errors.

Routers can be stacked or mounted on a wall.

Cisco 805 Router

The Cisco 805 router connects small professional offices over serial lines to corporate networks and to the Internet. Table 2 summarizes Cisco 805 router ports.

Table 2 Cisco 805 Router Ports

One 10BaseT (RJ-45)

Serial Port

One WAN interface (RS-232, RS-449, RS-530 and RS-530A, V.35, and X.21)

Console Port

RJ-45


The Cisco 805 router provides the following key features:

One serial WAN interface that delivers up to 512 kbps for synchronous serial connections (Frame Relay, leased lines, and X.25) or up to 115 kbps for asynchronous dial-up.

One Ethernet LAN interface.

Flash memory: 4 MB default, expandable to 12 MB.

Dynamic RAM: 8 MB, expandable to 16 MB.

Color-coded ports and cable reduce the chance of cabling errors.

Routers can be stacked or mounted on a wall.

Cisco 826, Cisco 827, and Cisco 827-4V Routers

The Cisco 826, Cisco 827, and Cisco 827-4V Series Routers provide the following key hardware features:

The routers provide connection to an ADSL network or telephones and fax machines through an ADSL port.

Flash memory: Default is 12 MB and is expandable to 20 MB. If 12 MB is Flash is installed, 8 MB is used for the Cisco IOS images and 4 MB hosts the ROMMON and NVRAM. Additional memory can be added using Flash cards.

Cisco 826 and Cisco 827 routers Dynamic RAM: Default is 16 MB of DRAM and is expandable to 32 MB.

Cisco 827-4V router Dynamic RAM: Default is 24 MB and is expandable to 32 MB. The Cisco 827-4V router also contains an 8-MB DIMM card.

The central processing unit is a 50 MHz MPC 855T RISC processor.

Color-coded ports and cable reduce the chance of cabling errors.

Routers can be stacked or mounted on a wall.

The routers provide locking power connectors and a Kensington-compatible locking slot.

New and Changed Information

The following sections list the new software features supported by the Cisco 800 series and Cisco 820 series routers for Release 12.2(2)XH2 and above.

New Software Features in Release 12.2(2)XH1

The following sections list the new software features supported by the Cisco 800 series and Cisco 820 series routers for Release 12.2(2)XH1.

IP Named Access Lists

Cisco 805 routers now support the IP Named Access Lists feature. Using this feature, you can identify IP access lists with an alphanumeric string (a name) rather than a number. Named access lists enable you to configure more IP access lists in a router than numbered access lists. This feature is required to support the Virtual Private Network (VPN) Solution Center, which does not operate with numbered access lists.


Note Release 12.2(2)XH supports the IP Named Access Lists feature on Cisco 801-804 routers only. Release 12.2(2)XH1 is required to use the IP Named Access Lists feature on Cisco 805 routers.


New Software Features in Release 12.2(2)XH

The following sections list the new software features supported by the Cisco 800 series and Cisco 820 series routers for Release 12.2(2)XH. Information is included for any changed or new command line interface (CLI) commands associated with the new features.

Committed Access Rate

Cisco 826, Cisco 827, and Cisco 827-4V routers now support Committed Access Rate (CAR). CAR can be used to rate-limit traffic based on certain matching criteria such as incoming interface, IP precedence, QoS group, or IP access list criteria. CAR provides configurable actions, such as transmit, drop, set precedence, or set QoS group, when traffic conforms to or exceeds the rate limit.

The CAR feature performs the following functions:

Limits the input or output transmission rate on an interface or subinterface based on a flexible set of criteria.

Classifies packets by setting the IP precedence or Quality of Service (QoS) group, which is a class identifier that is internal to the router.

IP Named Access Lists

Cisco 801-804 routers now support the IP Named Access Lists feature. Using this feature, you can identify IP access lists with an alphanumeric string (a name) rather than a number. Named access lists enable you to configure more IP access lists in a router than numbered access lists. This feature is required to support the Virtual Private Network (VPN) Solution Center, which does not operate with numbered access lists.

New Software Features in Release 12.2 T

For information regarding the features supported in Cisco IOS Release 12.2 T, refer to the Cross-Platform Release Notes and New Feature Documentation links at the following location on Cisco.com:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122relnt/xprn122t/index.htm

Important Notes

The following sections contain important notes about Cisco IOS Release 12.2(2)XH2 and above that can apply to the Cisco 800 series and Cisco 820 series routers. (Also, see the "Caveats" section.)

PPPoE MTU Adjustment Command Syntax Change

The syntax of the ip adjust-mss command has changed to the following command syntax:

ip tcp adjust-mss mss

where mss must be 1452 or less to fix the PPPoE Maximum Transmission Unit (MTU) problem.

Cisco 820 Series Memory Management When Using WFQ

When weighted fair queuing (WFQ) is used on the Dialer interface, or when WFQ is used in the default class of a service policy, the following parameters need to be set to the values shown because of the limited amount of memory on the router:

Congestive Discard Threshold: 64 or less

Number Dynamic Conversation Queues: 64 or less

Total maximum output packets: 64 or less

For example, if you apply WFQ to the Dialer interface, configure it as follows:

interface Dialer 1
 fair-queue 64 64 0
 hold-queue 64 out

In this example, the command fair-queue 64 64 0 limits the number of conversations to 64, and sets the discard threshold to 64. The command hold-queue 64 out limits the maximum number of output packets to 64.

In another example, if you configure a service policy, and WFQ is used on the default class, configure the policy as follows:

policy-map mypolicy
 class voice
  priority 100
 class class-default
  fair-queue 64
  queue-limit 64

 int dialer 1
 service-policy out mypolicy
 hold-queue 64 out

Here, the command fair-queue 64 limits the number of conversations to 64, and the command queue-limit 64 sets the discard threshold to 64. The command hold-queue 64 out limits the maximum number of output packets to 64. Failure to configure the above parameters may cause the router to display out-of-memory messages when a large amount of mixed traffic is transmitted from Ethernet to ATM.

Cisco 820 Series Router Clock—CSCdp09409

To run IPSec successfully, the Cisco 820 series router clock needs to be set accurately. Cisco 820 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 820 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 820 series router clock using the command clock set each time you restart the router.

The SNTP configuration documentation is available in the chapter "Monitoring the Router and Network" volume of the Configuration Fundamentals Configuration Guide in the Cisco IOS documentation set. The SNTP command reference documentation is available in the chapter "Router and Network Monitoring Commands" in the ""System Management Commands" volume of the Configuration Fundamentals Command Reference manual of the Cisco IOS documentation set.

CiscoView Application Support

The CiscoView application supports the Cisco 820 series routers. The CiscoView application provides dynamic status, statistics, and comprehensive configuration information for Cisco switches, routers, concentrators, and adapters. It displays a graphical view of Cisco devices. This network management tool also provides configuring and monitoring functions and offers basic troubleshooting tips.

Downloading Images

Before attempting to download new images, you must first delete files in the router Flash memory. Be sure to use the delete command, not command erase, to free up space. Entering erase removes all files, including the configuration.

Multilink PPP and Interleaving

Multilink PPP fragments large data packets so that small voice packets can be interleaved within them. However, apart from first-in-first-out (FIFO) queuing, no other kind of output queuing mechanisms are currently supported with PPP over ATM. Consequently, when multilink PPP is configured on the Cisco 827 routers, the big packets are fragmented, but interleaving of small voice packets within them does not occur.

NAT Support for H.323 Signaling

Currently, NAT does not support alerting H.225 messages. Therefore, NAT communication cannot be established between the router end points. NAT support for H.323 signaling is limited to the Netmeeting application.

Phone Mate Answering Machine Model 9200

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

ROM Monitor set stop-bits Parameter

This release supports the setting of 1 only, for the ROM monitor set stop-bits parameter.

Caveats

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 Releases 12.2 and 12.2 T are also in Cisco IOS Release 12.2(2)XH2. For information on caveats in Cisco IOS Release 12.2, see Caveats for Cisco IOS Release 12.2. For information on caveats in Cisco IOS Release 12.2 T, see Caveats for Cisco IOS Release 12.2 T  These two documents list severity 1 and 2 caveats and are located on Cisco.com and the Documentation CD-ROM.


Note If you have an account with Cisco.com, you can also use the Bug Toolkit to find select caveats of any severity.

Caveats for Release 12.2(2)XH

This section describes possibly unexpected behavior by software Release 12.2(2)XH.

CSCdu29516

Normally, the no ip route-cache command is applied to the dialer interface for the Ethernet interface to rate-limit incoming traffic. However, in this case, the dialer interface does not rate-limit incoming or outgoing traffic when ATM encapsulation AAL5 Point-to-Point Protocol (PPP) is used.

The workaround is to issue the ip route-cache command on the Ethernet interface if you are running ATM encapsulation PPP over Ethernet. All interfaces will then be able to rate-limit incoming and outgoing traffic.

CSCdu44295

On an intermittent basis, traceback occurs on the Cisco 801-804 routers that are running the 12.2(2)XH release. However, the traceback does not affect any other functionality.
