Cisco Bug: CSCuj89533 - 3850 applies dot1Q header to native vlan in LACP BPDU
Nov 27, 2020
- Cisco Catalyst 3850 Series Switches
Known Affected Releases
Symptom: Unable to form an LACP port-channel when using a native vlan other than vlan 1 because of unexpected tagged frame. Conditions: Found when trying to bundle an LACP port-channel between a 3850 switch running 3.2.2 and an ASR1000 router. A packet capture shows that a dot1Q header is added to the LACP BPDU (tagged) when using any vlan other than vlan 1. When using 'native vlan 1' on the port-channel, the capture shows the expected behavior of an untagged frame.
