Cisco 12000 Series Routers

Field Diagnostics is Not Supported on CSC or SFC Cards in OC192 Capable 12400 Routers with IOS below 12.0.26S


September 18, 2003



Problem Description

If a user attempts to run field diagnostics on a Clock Scheduler Card (CSC) or Switch Fabric Card (SFC) fabric card that resides in a OC192 capable Cisco 12000 router, the user will receive a banner that indicates that the card is not supported.

If a user attempts to run field diagnostics on a CSC or SFC fabric card that is on a OC48 capable Cisco 12000 router, the router may reload.

Background

Customers who suspect problems with their fabric cards, CSC or SFC, will be unable to run diagnostics succesfully on their router. In the case of 2.5Gig fabric configurations, router behavior may be unpredictable in releases between 12.0(22)S and 12.0(25)S.

Problem Symptoms

Running field diags on CSC or SFC in Cisco 12000 OC192 capable routers was not supported between IOS releases 12.0(22)S and 12.0(25)S.

Workaround/Solution

IOS releases 12.0(26)S and higher will allow customers to run field diags on CSC and SFC cards within a Cisco 12404, 12406, 12410, or 12416.

Customers who do not want to upgrade their IOS release should not run field diags on CSC or SFC cards if they reside in a 10Gig fabric based Cisco 12404, 12406, 12410, or 12416.
