Problem: N7K-M132XP-12 Linecard PortLoopback Test Failure ![]() If the issue is fixed by reload, the root cause is related to Cisco bug ID CSCus22805.If the issue is seen after reload, you need a hardware replacement.Reload the problem Supervisor, if possible.A reset/reboot of the board rediscovers these failed flashes are healthy at the next boot up.Ĭomplete these steps in order to verify if this is or is not a hardware issue: There are a few instances in the field where one or both of these flashes are marked as bad by the RAID software over a time span of several months or years in service. With the redundancy, a Supervisor can function with the loss of one of the flashes but not both. These two flashes are reconfigured as a Redundant Array of Independent Disks (RAID) 1 array which implements internal mirroring. The flashes provide a repository for bootflash, configurations, and other pertinent information. Second generation Nexus 7000 Supervisors are shipped with two identical eUSB flashes for redundancy.

Note: The exact format of the syslog and error messages that this document describes can vary slightly. This document provides a brief explanation and solutions for common hardware and architecture issues for Cisco Nexus 7000 Series switches that run Cisco NX-OS system software.
