Cisco Bug: CSCsg40016 - show tech causes various system problems
Feb 21, 2018
- Cisco IOS
Known Affected Releases
Symptom: When the "show tech" command is issued on Catalyst 6500 switches running Modular IOS, it may temporarily stop sending control traffic like HSRP, EIGRP, PIM and cause adjacency resets. This command may also result in communication failures between the Sup engines / modules and/or cause hardware reset. This issue happens when the command issued either from Switch Console or via Telnet / SSH session. Conditions: Sup720 engines running 12.2SX Modular IOS releases and the "sh tech" results redirected to any of the file systems in the switch.
