Cisco Bug: CSCvs34826 - show tech fabric collection triggers continuous spio Invalid arguments log messages on ASR 9000
Jun 16, 2020
- Cisco ASR 9000 Series Aggregation Services Routers
Known Affected Releases
Symptom: After executing "show tech-support fabric" on Cisco ASR 9000 router running 6.6.3 software, continuous log messages as below start appearing in log buffer every 6 minutes. RP/0/RSP1/CPU0:R11-PE3-A9006#show logging | i spio Thu Dec 5 13:52:08.834 UTC RP/0/RSP1/CPU0:Dec 5 13:41:28.586 UTC: spio_pd_show_protocol_ltrace: Invalid arguments RP/0/RSP1/CPU0:Dec 5 13:47:28.928 UTC: spio_pd_show_protocol_ltrace: Invalid arguments RP/0/RSP1/CPU0:R11-PE3-A9006# These logs are actually triggered by "show spio platform protocol all trace" command, but since "show tech fabric" includes this "show spio" command, the logs are seen when show tech fabric collection is done as well. It seems ziplogger/paltx is being invoked when "show spio platform protocol all trace" command is executed, but maybe not properly, and that results in the log messages. Conditions: Execute "show spio platform protocol all trace" or "show tech-support fabric" on ASR 9000 routers running IOS-XR Release 6.6.3 software.
