Cisco Bug: CSCvt85758 - Catalyst 9k may drop individual larger packets when agressive storm control values are configured
Jul 27, 2020
- Cisco IOS
Known Affected Releases
Symptom: Individual packets that otherwise conform to storm-control criteria may be discarded by the switch when aggressive storm control values are used (less than 1%) This may impact protocols like DHCP or routing protocol hellos where we expect a single large broadcast or multicast packet to be processed locally by the switch as part of normal protocol operation. Conditions: Seen on cat9k products running any software where the packet that is being discarded ingresses on an interface configured with a storm control value of less than 1%.
