Known Affected Releases
Symptom: When we have both "PVLAN Promiscuous veth ports"(1) and "PVLAN Host mode"(2) veth ports having the same primary VLAN, port security cannot be enabled on veths in (1), since we will have PVLAN static macs configured for veths in (2) on the primary vlan. Pre-Requisites:: 1. One vethernet interface(veth x) which is in PVLAN Host Mode with Primary vlan "A" and secondary vlan "B. 2. One vethernet interface(veth y) which is in PVLAN Promiscuous mode with Primary VLAN "A" and secondary vlan "C" Condition: With "veth x" already UP, PVLAN static MACs will be programmed on Primary vlan "A". With this condition, when port security is enabled on "veth y", it will fail.
