Important Notes
The following sections contain important notes about Cisco IOS Release 12.1(2)XF5 that can apply to
the Cisco 811 and 813 Routers. (Also, see the “Caveats” section on page 11.)
Caveat CSCdr91706 and IOS HTTP Vulnerability
A defect in multiple releases of Cisco IOS software causes a Cisco router or switch to halt and reload
if the IOS HTTP service is enabled and you browse to http://router-ip/anytext?/ and enter the enable
password when it is requested. This defect can be exploited to produce a denial of service (DoS) attack.
This vulnerability can only be exploited if the enable password is known or not set.
The vulnerability, identified as Cisco bug ID CSCdr91706, affects virtually all mainstream Cisco
routers and switches running Cisco IOS software releases 12.0 through 12.1, inclusive. This is not the
same defect as CSCdr36952.
The vulnerability has been corrected and Cisco is making fixed releases available for free to replace all
affected IOS releases. Cisco urges all customers to upgrade to releases that are not vulnerable to this
defect as listed in the complete advisory,which is available at: http://www.cisco.com/warp/public/707/
ioshttpserverquery-pub.shtml. You are strongly encouraged to read the complete advisory.
System Requirements
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.
Cisco 800 Series Router Clock—CSCdp09409
To run IPSec successfully, the Cisco 800 series router clock needs to 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.
The SNTP configuration documentation is available in the chapter “Monitoring the Router and
Network” in the “System Management” volume of the Configuration Fundamentals ConfigurationGuide 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 in the Cisco IOS
documentation set.

System Requirements
CiscoView Application Support
The CiscoView application supports the Cisco 800 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.
Dial Peer Limitation
The isdn answer1 and isdn answer2 commands determine which called telephone numbers, for
example, 555-1111 and 555-2222, a Cisco 800 series router can answer. Using these commands limits
a router to using the two dial peers that contain the telephone numbers 555-1111 and 555-2222. (When
not using these commands, a router can use up to six dial peers.) A sample scenario in which the isdnanswer1 and isdn answer2 commands are used is when a Cisco 801 or Cisco 803 router is connected
with other ISDN devices to an ISDN S-bus.
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.
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:
• IP
• User Datagram Protocol (UDP)
• IPX
• Cisco Discovery Protocol (CDP)
• Simple Network Time Protocol (SNTP)
See the Cisco 800 Series Routers Software Configuration Guide to set up extended access lists to
preventIP, UDP,IPX, and SNTP updates from activating the ISDN line. For CDP, make certain 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 fails the POST tests during boot
and causes the router to halt. The only way to recover from this state is to pull apart the soldered boot
Flash and re-burn the Boot ROM. This problem has been resolved in TinyROM version 1.0(3), a
downloadable ROM upgrade available from Cisco.com. Contact Cisco to upgrade to this version or
later, and prevent this problem from occurring.

78-11070-02, Rev. H0
Phone Mate Answering Machine Model 9200
A Phone Mate answering machine model 9200 failed 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.
PPP over Frame Relay Support (RFC-1973)
Cisco 800 series routers do not support PPP protocol over Frame Relay.
TACACS+ with AAA
Cisco 800 series routers now support the Terminal Access Controller Access Control System Plus
(TACACS+) protocol through Telnet. TACACS+ is a Cisco proprietary authentication protocol that
provides remote access authentication and related network security services, such as event logging.
User passwords are administered in a central database, rather than in individual routers. TACACS+ also
supports separate modular authentication, authorization, and accounting (AAA) facilities that are
configured at individual routers.
For information on how to configure TACACS+, refer to the “Configuring TACACS+” chapter in the
Security Configuration Guide. For information on TACACS+ commands, refer to the “TACACS,
Extended TACACS, and TACACS+ Commands” chapter in the Security Command Reference.
Cisco 800 series routers do not support the following protocols:
• TACACS, an older access protocol now deprecated by Cisco, or Extended TACACS, an extension
to the TACACS protocol.
• RADIUS or Kerberos protocols.
System Requirements
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 or defects 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.
All caveats in Release 12.1(2)T are also in Release 12.1(2)XF5. For information on caveats in Cisco
IOS Release 12.1(2)T,refer to the Caveats for Cisco IOS Release 12.1 T document. For information on
caveats in Cisco IOS Release 12.1, refer to the Caveats for Cisco IOS Release 12.1 document. These
