Cisco Bug: CSCvt48482 - Certain VLANs on vPC leaf pair are not programmed correctly
May 07, 2020
- Cisco Nexus 9000 Series Switches
Known Affected Releases
Symptom: The ELAM shows the ARP request coming into the leaf on the correct port but there is no SRC_VLAN_MBR even though the VLAN is not programmed on port-channel where frame is coming in on. Conditions: The issue only seemed to be specific to BUM traffic because if we forced a unicast ARP request traffic begin to work which is a bit puzzling considering the VLAN is not deployed. This was seen in a vmm integrated environment with intermediate HP VCs. This happened on two different sets of vPC leaf switches.
