Problem Description

A traffic outage could occur on the 15454-MRC-12, 15454-MRC-4, or 15454-DS3XM-12.

Background

A traffic outage on the 15454-MRC-12, 15454-MRC-4, or 15454-DS3XM-12 could occur under certain conditions when upgrading to release 8.0.

Problem Symptoms

1. Software upgrade from a release prior to 8.0 to 8.0 causes:

   1. Multi-Second outage on the 15454-DS3XM-12 card in the Main slots 1, 3, 5, 12, 14, and16 when an XC or XCVT cross connect card is used.

   2. Complete outage on the 15454-DS3XM-12 card in the Protect slots 2, 4, 6, 13, 15, and 17 when an XC or XCVT cross connect card is used.

   3. Multi-Second outage on the 15454-MRC-12 card when an XC or XCVT cross connect card is used.

   Note: Support for the 15454-MRC-4 card first appears in Release 8.0. Consequently, the software upgrade issue does not apply to the 15454-MRC-4 card.

2. Soft reset in 8.0 causes:

   1. Multi-Second outage on the 15454-DS3XM-12 card in the Main slots 1,3,5,12,14, and 16 when the active XC or XCVT cross connect card is in slot 8.

   2. Total Outage of the 15454-DS3XM-12 card in the Main slots 1, 3, 5, 12, 14, and 16 when the active XC or XCVT cross connect card is in slot 10. A hard reset will clear the problem, but a further soft reset will again cause an outage.

   3. Multi-Second outage on the 15454-DS3XM-12 card in Protect slots 2, 4, 6, 13, 15, and 17 when the active XC or XCVT cross connect card is in slot 10.

   4. Total Outage of the 15454-DS3XM-12 card in Protect slots 2, 4, 6, 13, 15, and 17 when the active XC or XCVT cross connect card is in slot 8. A hard reset will clear the problem, but a further soft reset will again cause an outage.

   5. Multi-Second outage on the 15454-MRC-12 card when an XC or XCVT cross connect card is used.

   6. Multi-Second outage on the 15454-MRC-4 card when an XC or XCVT cross connect card is used.

Workaround/Solution

Replacing the XC or XCVT with a 10G capable cross connect resolves the problem.

Trade-in programs are available to replace your XC or XCVT with either an XC-VXC-10G or XC-10G cross connect card. Access to the Trade-in tool is located at the Cisco Technology Migration Plan (registered customers only) page.

There is no workaround in Release 8.0 when using the 15454-MRC-12, 15454-MRC-4 or the 15454-DS3XM-12 with the XC or XCVT cross connect cards.

If you are unable to replace your XC or XCVT cards, the issue will be addressed in Release 8.5.
