- Connected interfaces under a VLAN. - Bridge Protocol Data Unit (BPDU) is not transmitted through BIG-IP which is in passthrough mode. - Can see DST MAC STP (Mac: 01:80:c2:00:00:00) IN packets and missing OUT packets in TCP dump. - No packet drop for DST MAC PVST (MAC:01:00:0C:CC:CC:CD) and VTP (MAC:01:00:0C:CC:CC:CC). tshark -nnr < .pcap >
BPDU packets will not pass through other devices if BIG-IP is in the middle of the topology with passthrough mode enabled.
- Platforms C117, C115, C112, and C113
None
STP passthrough mode now works as expected on C117, C115, C112, and C113 platforms
