RECENT FIELD NOTICES

Title: Cisco Catalyst Supervisor Remote Reload
URL: http://www.cisco.com/warp/public/770/cat7161-pub.shtml (available to guest and registered users)
Summary: A software bug (Cisco bug ID CSCdi74333) allows remote TCP/IP users to cause reloads of Cisco Catalyst LAN switches running Catalyst 5000 supervisor software versions from 1.0 through 2.1(5). The affected software was last shipped with new units in early 1997. In addition to the Cisco Catalyst 5xxx series, some, but not all, Catalyst 29xx family switches may run the affected software; see "Who is Affected" for more information. A similar bug, Cisco bug ID CSCdj71684, exists in the supervisor software for the older, and now discontinued, Cisco Catalyst 12xx family, up through software Version 4.29. Fixes are available for both bugs.

Title: Changes made to the Cisco Year 2000 Product Compliance Page
URL: http://www.cisco.com/warp/customer/752/2000/y2k_changes1.1.htm (available to guest and registered users)
Summary: This page refers to changes made to the Cisco Year 2000 Product Compliance page at /warp/public/cc/cisco/mkt/gen/2000/prodlit/cptbl_ov.htm.

Title: Cisco 7xx TCP and HTTP Vulnerabilities
URL: http://www.cisco.com/warp/customer/770/7xxconn-pub.shtml (available to guest and registered users)
Summary: This notice addresses two unrelated security vulnerabilities in the software used on the Cisco 7xx series of small-office and home-office routers. These vulnerabilities affect only the Cisco 7xx series routers (not the Cisco 7xxx series); no other Cisco product is affected. The first vulnerability, which has been assigned Cisco bug ID CSCdm03231, can be used to cause system reloads, and therefore denial of service, using TCP connections to the Telnet ports of the routers. The second vulnerability has not been assigned a bug ID. Cisco 7xx routers running software Versions 3.2(5) through 4.2(3) support a simple HTTP server. This HTTP server is enabled by default. Unless the server is explicitly disabled, it can be used to make changes to the router configuration, or to gain information about that configuration. This is intentional behavior, but it is mentioned in this notice because it appears that customers have been caught unaware by it. There are configuration workarounds for both of these vulnerabilities.

Title: UXM IMA with T1 Backcard Logs Trunk Failures upon Clock Switches of Node
URL: http://www.cisco.com/warp/customer/770/fn1949_03091999.html (available to guest and registered users)
Summary: UXM IMA groups using the T1 backcard experience "IMA Group Failure" when there is a clock switch on the node. This situation leads to temporary communication breaks and clock switches on downstream nodes if a failed trunk is the source of the clock.

Title: 9.1 - 8.5 Interoperability Loop Clock Not Passing on Trunks
URL: http://www.cisco.com/warp/customer/770/fn3809_03041999.shtml (available to guest and registered users)
Summary: Pass sync cannot be set on a trunk when one node is running switch software 8.5.x and the other node is running 9.1.x. An error message is displayed, indicating that you cannot set pass sync on a trunk when the other side is set for loop clock. When the other side of the trunk config is checked, however, loop clock is not configured.

Title: CX-TRIP Token Ring Data Corruption Recall Announcement
URL: http://www.cisco.com/warp/customer/770/fn2808_03011999.shtml (available to guest and registered users)
Summary: Cisco has discovered a problem with the CX-TRIP Token Ring Interface Processor used on the Cisco 7000 series of routers. Affected CX-TRIP units can sometimes incorrectly transfer Token Ring packets to and from the memory of the router. The resulting packets have their payload data corrupted at random locations within the packet.

Title: Port Adapter Compatibility for Cisco 7200 VXR Routers
URL: http://www.cisco.com/warp/customer/770/fn3028.html (available to guest and registered users)
Summary: The release of the new Cisco 7200 VXR router requires certain port adapter updates for forward compatibility. This requirement is due to the new and higher speed PCI midplane in the Cisco 7200 VXR router. Only port adapters used in Cisco 7200 VXR routers require this update. Because all port adapters are not upgradable, some port adapters are not supported in Cisco 7200 VXR routers. Only port adapters addressed in this field notice are affected. All other port adapters are not affected and are compatible with Cisco 7200 and 7200 VXR routers unless previously documented as not supported in the Cisco 7200 router. Those port adapters will not be supported in the Cisco 7200 VXR router. Cisco 7200 routers are not affected by this change.

Title: Fax Failure on IGX-UVM in Software Release 9.106 and Earlier 9.1
Releases
URL: http://www.cisco.com/warp/customer/770/fn3488_02181999.shtml
(available to guest and registered users)
Summary: Fax and modem transmissions fail because permanent virtual
circuits (PVCs) terminated on universal voice modules (UVMs) do not
increase bandwidth to 64 Kbps. Fax and modem transmissions require that
the PVC bandwidth upgrade to full 64 Kbps (or a Cisco-proprietary 32 Kbps
bandwidth) in order to properly negotiate the protocols between the two
end devices.

Title: Channelized Voice Module (CVM) and Channelized Data PAD
PVCs Remain in Modem Upgrade Mode after Call Termination
URL: http://www.cisco.com/warp/customer/770/fn3648_02181999.shtml
(available to guest and registered users)
Summary: After a modem call is placed, permanent virtual circuits
(PVCs) terminating on CVMs fail to return to the downgraded state. Trunk
bandwidth is used unnecessarily and may prevent the affected connection
and other connections from proper operation.

Title: Standby Broadband Controller Card (BCC) Goes into UP Failure When Primary Clock Goes into Alarm
URL: http://www.cisco.com/warp/customer/770/fn3630_02161999.shtml (available to guest and registered users)
Summary: Removing or recovering the primary or secondary clock sources from the network can cause the standby BCC to momentarily get out of synchronization.

Title: BPX Switch Unable to Reroute Connections to a Trunk with the Maximum Channels Set to a Maximum Value
URL: http://www.cisco.com/warp/customer/770/fn3629_02161999.shtml (available to guest and registered users)
Summary: BPX(r) connections will not route if the best path is over a BXM trunk that has been configured to use the maximum number of channels supported by the BXM card. Connections may take longer to route (up to five times longer) over a BXM trunk that has been configured to use one less than the maximum number of channels supported by the BXM card. The channels configured for a BXM trunk can be verified or changed with the "Max Channels/Port" field on the cnftrk command display.

Title: Software Image Management (SWIM) Issues in Cisco IOS Software
URL: http://www.cisco.com/warp/customer/770/fn2868_02151999.shtml (available to guest and registered users)
Summary: Multiple severe defects, originating in Cisco IOS software Releases 12.0(1), 12.0(2), 12.0(1)T, 12.0(1)T1, 12.0(1)XA3, 12.0(1)XB, 12.0(1)DB, 12.0(1)XD, and 12.0(1)XE, have critically impacted the SWIM application. Customers running Cisco IOS 12.0(1) or later releases that are affected will be unable to perform automated Cisco IOS software and boot loader upgrades using the SWIM application.

Title: Essentials 2.0 SyslogAnalyzer Incorrectly Parses Time Stamp
URL: http://www.cisco.com/warp/customer/770/fn2848_02101999.shtml (available to guest and registered users)
Summary: The Essentials 2.0 SyslogAnalyzer is incorrectly parsing the Time-stamp field of syslog messages. Syslog messages generated on mm/dd/1999 are stored in the database with a mm/dd/1998 time stamp. There is an exception for the Essential 2.0 users who have enabled service time stamp in their routers; service time stamp produces a year field in the time stamp.

Title: IGX(tm) Alarm Relay Module (ARM) Deactivates after Two Consecutive switchcc Commands
URL: http://www.cisco.com/warp/customer/770/fn3248_02051999.shtml (available to guest and registered users)
Summary: The IGX ARM switches from "active" to "standby" after two consecutive switchcc commands. The impact to the customer is that the node and network alarms that activate external warning devices such as bells or lamps cease to operate. This scenario may result in alarms going unnoticed, delaying the resolution response actions to correct the alarm condition. Additionally, after the first switchcc command, the alarm history is irrecoverably lost.
