Release Notes for the Cisco 805 Router
This document describes new and changed information for the following documents:
•Quick Start Guide: Setting Up the Cisco 805 Router
•Cisco 805 Router Software Configuration Guide
Cisco 805 Router Enhancements
The Cisco 805 router now supports the following features:
•Hot Standby Routing Protocol (HSRP), which creates a Hot Standby router group with a lead router that services all packets sent to the Hot Standby address. The lead router is monitored by other routers in the group. If it fails, one of these standby routers inherits the lead position and the Hot Standby group address.
•Service Assurance Agent (SAA), which is both an enhancement to and a new name for the Response Time Reporter (RTR) feature that was introduced in Cisco IOS release 11.2. This feature enables you to monitor network performance by measuring key Service Level Agreement (SLA) metrics, such as response time, network resources, availability, jitter, connect time, packet loss, and application performance.
•Triple Data Encryption Standard (3DES), based on the standard cryptographic algorithm developed by the U.S. National Bureau of Standards.
•X.25 protocol over TCP/IP for both the B and D channels.
•Protocol Independent Multicast (PIM) Sparse mode is now supported on the Cisco 805 router.
For more information about these features, see the IOS documentation set.
TinyROM Version 1.4(1) Enhancements
TinyROM performs the following functions for Cisco 800 series routers:
•Starts power-on self-test (POST) and makes minor configuration adjustments
•Loads and boots an IOS software image
•Uploads a new IOS software image
TinyROM has been enhanced to handle multiple Cisco IOS boot system commands to ensure that your Cisco 800 series router boots with the IOS software.
The behavior of the IOS boot system command depends on which versions of TinyROM and IOS software you have installed on your router. The following section describes the behavior of various combinations of TinyROM and IOS software.
To view which versions of TinyROM and IOS are installed on your router, use the show version command in Exec mode.
Note For more information about Cisco IOS commands, see the IOS documentation set.
TinyROM and Cisco IOS Behavior
Table 1 summarizes the behavior of TinyROM and IOS software versions.
Workaround for Earlier Versions of TinyROM
If you have TinyROM version 1.2(2) or later, you can rely on the boot fallback capability to ensure that IOS is booted, provided that you have at least one IOS image stored in Flash memory that is not marked for deletion.
Note If you have TinyROM version 1.2(1) or earlier installed on a remotely administered router, we strongly recommend that, at a minimum, you upgrade the IOS software. Using the workaround documented in this section will always boot IOS, but this procedure is susceptible to user error. Even a minor error could result in IOS not booting on your router.
If you have TinyROM version 1.2(1) or earlier, ensure that IOS will be booted by following these steps:
Note This step does not require the Flash file system designation (flash: preceding the filename).
You should have only one boot system command in your configuration that specifies the file to boot. To verify your configuration, use the show running-config command. To obtain a list of filenames, use the dir command. Files marked with -r-x are valid IOS boot file images. For more information, see the output example following these steps.
The following examples show the screen output for the show run and dir commands:router# show runBuilding configuration...Current configuration:!version 12.1!boot config flash:backup-configboot system flash c800-nsy6-mwlogging buffered 4096 debugging!...router# dirDirectory of flash:/0 ---- 49088 Jan 20 2000 05:11:57 TinyROM-1.2(1)1 ---- 49088 May 12 2000 04:43:56 TinyROM-1.3(1)2 -r-x 3664268 May 19 2000 22:07:32 c800-nsy6-mw58 -r-- 750 <no date> backup-config12582912 bytes total (8716288 bytes free)router#
Upgrading TinyROM and IOS Software
To upgrade TinyROM and IOS software, do the following:
•First upgrade TinyROM and then upgrade IOS. This is the recommended sequence.
•Use the Trivial File Transfer Protocol (TFTP) to upgrade IOS. It is faster and easier to do so by using TFTP.
•You need access to a console to upgrade TinyROM because you cannot do so over the WAN. For more information, refer to the "ROM Monitor,"section in Appendix A of the Cisco 805 Router Software Configuration Guide.
•After upgrading IOS, enter the write memory command so that the new version of IOS properly configures the boot order. If you are using the boot config feature, copy the full-config file from Flash memory to the running-config file, as in the following example:boot# copy flash:full-config running-config
Note To obtain the name of the full-config file in Flash memory, review the boot config section of the output for the show startup-config command.
Quick Start Guide: Setting Up the Cisco 805 Router

CD LED Explanation
The explanation of the CD LED in the Verify the Router Connections table is incorrect. The explanation should be as follows. (The footnote still applies.)
On when the serial interface is up and a carrier signal is detected.
Cisco 805 Router Software Configuration Guide
This section describes new and changed information for the Cisco 805 Router Software Configuration Guide.
Upgrading Software from the Command-Line Interface
When upgrading your software from the command-line interface (CLI), replace Step 5 with the following:
Mark the running image in Flash memory as deleted:router# erase flash
Note Entering the erase flash command marks the running image in Flash memory as deleted in addition to all other nonrunning files and images.
By marking the running image in Flash memory as deleted, you can upgrade the software and not change the current running operation of the router.
