WHAT'S HOT

Title: Find Information Quickly Using the Technical Assistance Center Guide!
URL: http://www.cisco.com/tac (available to registered users)
Summary: The Cisco Technical Assistance Center (TAC) Guide, a new resource on the TAC Web site, is designed to help you find relevant technical information quickly. The TAC Guide lets you enter words, phrases, or entire questions into a text box; based on the query submitted, the system delivers logical responses and ranks them according to relevance. A Cisco networking expert customized the artificial intelligence behind this tool to ensure it would deliver the pertinent results you need with the ease of use you want. The TAC Guide streamlines searches and enables you to access critical information quickly.

Title: Cisco Product Pages Link to Critical Product Support Data
URL: http://www.cisco.com/cgi-bin/Support/PSP/index.pl?i=Hardware (available to registered users)
Summary: The Cisco Product Pages, available through the Technical Assistance Center Web site, deliver comprehensive technical support information to the engineering community.

RECENT FIELD NOTICES

Title: R5000 250MHz CPU Problem
URL: http://www.cisco.com/warp/customer/770/fn7991_10111999_form.html (available to registered users)
Summary: Under certain conditions, a small percentage of the line card CPUs are experiencing failures due to noise inside the CPU. In this field notice, customers may request their affected line cards be returned to Cisco for upgrading.

Title: UVM With Firmware Model E Version B Drops Signaling
URL: http://www.cisco.com/warp/customer/770/fn6750_10131999.html (available to registered users)
Summary: UVM with firmware D.E.B will drop signaling in Channel Associated Signaling (CAS) mode. This affects both J1 circuits. The customer impact is that random channels on the J1 interface will not function.

Title: After 9.1 to 9.2 Software Upgrade User Connections May Fail
URL: http://www.cisco.com/warp/customer/770/fn7711_10061999.shtml (available to registered users)
Summary: After a 9.1 to 9.2.20 switch software upgrade, some of the nodal connection resources are allocated to both user permanent virtual circuits (PVCs) and control card PVCs, which results in user traffic to be adversely affected. Networking connections used for internal, internode communications are not affected.

Title: MGX(tm) 8800 Jitter Problems on PXM1-4-155 OC-3 Ports
URL: http://www.cisco.com/warp/customer/770/fn7931_10081999.shtml (available to registered users)
Summary: Cisco has discovered two problems with jitter on the OC-3 ports of the PXM1-4-155:
1) Excessive jitter caused by a programmable logic device (PLD) mismatch on the OC-3 daughtercard attached to the PXM1. This affects some units that have part numbers beginning with 800-05086, but there is no way to identify which units are affected. Part numbers beginning with 800-05762 are not affected.
2) Excessive jitter caused by a software bug when it configures the transmit clock.

Title: Cisco IOS Software Release 12.0-based Images Require 64 MB of DRAM Memory for Some Platforms
URL: http://www.cisco.com/warp/customer/770/fn6610_10081999.html (available to registered users)
Summary: The platforms listed in this field notice require a minimum of 64 MB of dynamic RAM (DRAM) to run Cisco IOS 12.0, 12.0T, 12.0S, 12.0XE, 12.0XI, 12.0.3c-W5, and later images.

Title: Boot Flash Size Too Small for Next Release of Catalyst 8540MSR
URL: http://www.cisco.com/warp/customer/770/fn7871_10071999.html (available to registered users)
Summary: The current boot Flash size on Catalyst 8540 route processors is 8 MB. The next release of Multiservice Switch Router (MSR) Cisco IOS software is larger than 8-MB. Initially, the 8 MB boot Flash SIMM was sufficient because image sizes were only 3 to 4 MB. As the number of features and line cards increased, the image size has grown beyond 8 MB.

Title: Cisco 12000 Series Gigabit Switch Router (GSR) Cooling Issues
URL: http://www.cisco.com/warp/customer/770/fn5990_07021999.shtml (available to registered users)
Summary: This field notice addresses two separate issues on the GSR 12008.
Issue 1: GSR 12008 Cooling: If the ambient (room) air temperature is above 40 degrees C (104 degrees F), some existing GSR 12008s may not be able to adequately cool themselves.
Issue 2: CSC-8: There is a potential problem with CSC-8 cards in the GSR 12008 main fan tray. CSC-8 cards provide power to the GSR 12008 main fan tray. This potential problem can cause a power loss to the fan tray, cause the GSR 12008 to overheat, and eventually cause a shutdown.

Title: Cisco 12000 Series Line Card Buffer Management ASIC (BMA) Synchronous Dynamic RAM (SDRAM) Errors
URL: http://www.cisco.com/warp/customer/770/fn6530_09291999.shtml (available to registered users)
Summary: A memory timing problem affects Cisco 12000 series line cards that have 64 MB of packet buffer memory. The line card may experience console error messages and packet corruption and dropped packets may occur.

Title: Cisco Secure Intrusion Detection System (NetRanger): packetd Fails to Start
URL: http://www.cisco.com/warp/customer/770/fn7651_09241999.html (available to registered users)
Summary: In specified Cisco secure intrusion detection system sensors, the packetd process fails to start, or fails within two minutes of starting. File permissions for the license file /usr/nr/etc/licenses are incorrect. As a result, packetd is unable to read its license and aborts at startup.

Title: UFM Reports UBU Errors HWY 1 or 5
URL: http://www.cisco.com/warp/customer/770/fn1127_09221999.shtml (available to registered users)
Summary: The IGX node event log may contain entries similar to the following: "Info Bus A Reports 1 Error(s) on Slot 3 HWY 1 (UBU)." If user data is not affected, then the bus errors can be ignored. This problem only occurs when operating 9.1 or later versions of switch software. Versions of software prior to 9.1 do not monitor bus parity errors.

Title: VCO Deleted ICC Span Maintains Original Timeslot Assignments
URL: http://www.cisco.com/warp/customer/770/fn7291_09201999.shtml (available to registered users)
Summary: When an ICC span is deleted from the database, the ICC continues to transmit on the timeslots that were assigned to it before its deletion from the database. This problem occurs when this or another span is added to the database. The Generic Call Control software dynamically re-assigns to the recently configured span, which are the same timeslots that were used by the deleted ICC span. The ICC continues to transmit on these timeslots. The result is extraneous transmissions on the re-assigned timeslots.

Title: VNS Voice Calls Exhibit Poor Quality
URL: http://www.cisco.com/warp/customer/770/fn7531_09161999.shtml (available to registered users)
Summary: Voice connections set up by voice network switching (VNS) may experience poor quality with IGX switch software versions 9.1.00 through 9.1.15.

Title: Cisco 7500 HSA Write Memory Symptom
URL: http://www.cisco.com/warp/customer/770/fn7431_09161999.shtml (available to registered users)
