Sep 13, 2018
- Cisco Catalyst 4500 Series Switches
Known Affected Releases
Symptom: Primary switch configured in VSS may crash within IOSd when using 'show switch virtual link counters' after the port channel goes down. The following maybe seen from the terminal: >> Moving an interface from vsl to non-vsl, while system is running, might cause loop in the network. So, interface is being put to admin down state. Please execute `no shutdown` on the interface to remove admin down state >> Conditions: This is seen in a VSS setup with etherchannel manually configured on both sides of the port channel. Using 'show switch virtual link counters' following removal of the channel-group from all ports in the bundle can trigger this crash.
