Nov 22, 2019
- Cisco Nexus 9000 Series Switches
Known Affected Releases
Symptom: On reload, vPC interfaces are temporarily brought online and then brought down. During this transition, traffic loss may be seen for 3-10 seconds. Conditions: This issue occurs after leaf reload and affects vPC port-channels. This is most prevalent when using port channels in mode-on (that is, with LACP disabled). It can also occur under high scale environments with large number of VLANs configured on multiple interfaces.
